Vintage Burglar and Fire Alarm System In A 1970’s Mansion

[@ExitSign250]

After many viewer comments providing more insight on some aspects of the video, I’d like to make a few corrections: 1) The heat detectors shown throughout the video are resettable, not one time use. 2) The Ademco device shown at 26:09 is a vibration sensor (Model 11) that is still in production. I could not find any information on it for some reason when recording this video. 3) The devices shown at 6:30, 9:25, and in the epilogue of this video are motion detectors, not ultrasonic glass break detectors. In hindsight, this would make better sense as all of the windows were protected by vibration sensors. I had no idea motion detectors were available for residential uses when this system was installed! 4) The jacks on the panic stations are for use with a button on a cord. A common scenario would be in a bedroom. The panic station would be mounted on the wall while the button on a cord would be plugged in laying on a nightstand beside the bed. This allows the panic alarm to be activated easier by grabbing the button on the cord rather than to reach up and press the buttons on the station.

[@ransomha]

The motion detectors don't look like PIR, rather they look more like sonic distance sensors. Perhaps that's just the technology used in 1970s security systems, and definitely can still detect motion. I used some of those for a parking garage light once. Pretty interesting

[@NickyDrops]

I remember tryin not to trigger them as a kid. Definitely motion of sorts.

There is so much stuff that are older than everybody think, they were just far far high cost. I remember a flat LCD tv set in the early 2000' priced 7 000 € you can now get for 100-150 In the 80 you already have stuff to remote control you house thought a network, it was not internet but the phone network and it cost a lot more than googazone stuff (but with far more personal data protection) Have fun with this oldies (can use autotranslate kzbin.info/www/bejne/Y4Wch3duoq6Ynbs )

[@Mpg-gh5fq]

The system at my grandparents' house was set up with a panic station on the wall on one side of the bed, and a pushbutton was plugged into the jack and run over to the nightstand on the other side of the bed. That way, either person in the bed had a device on their own side of the bed that they could use to activate the alarm (the panic station's built-in button on one side or the corded pushbutton on the other side) without requiring help from the other person.

[@Rob_M_Jr]

I can help with a couple things, I have been in the alarm industry for over 30 years. That ADEMCO vibration sensor is a model 11, and in fact, it is still in production. Its often used on safes, vaults and the like. The recessed sensor by Detection Systems is A DS903 passive infrared detector. And it was intended to be installed just like you found it, behind a duplex receptacle cover. I love collecting old burg and fire components too, you definitely found a few rare items!

[@ExitSign250]

I appreciate it! Wow, I spent hours trying to find information about that Ademco sensor without luck. That’s hilarious it’s a part still in production. And I had no idea about that Detection Systems sensor. In the epilogue of this video I stated that it was an early glass break detector, however in hindsight if they had the Ademco model 11’s there would be no need for a break glass sensor. (If they were even available at the time) Those being motion detectors makes better sense, although they didn’t seem to be motion detectors at first glance. I’d like to fire them up and see how they work or if I’m able to get them working. Thank you for your many informative comments!

[@Rob_M_Jr]

@ExitSign250 You should be able to power that motion with 6-18vdc. The battery is not required to make them function, it was optional if you were powering the unit from 12vac, just like the photo beams from the same era. I would love to see it working!

[@ExitSign250]

Got it. I’ll do some testing. Thanks!

[@dieseldragon6756]

That's an *old* old design of PIR sensor, if that's what it is! When he took the receptacle cover off, I thought we were looking at an ultrasonic device! 😁 Mind you, I think disguising them as outlets can be a bit tricky. Remember the first one we saw? A *lot* of people have mistaken that for a usable power outlet over time... 🔌🚫🙃

[@Rob_M_Jr]

@dieseldragon6756 definitely an old design, and it is 100% a pir. There was also a DS903E that had an adjustable range. Detection Systems designed it to blend in. In fact, the DS403 was a photo beam that also used a duplex receptacle cover to blend in.

[@mbcommandnerd]

6:08 - NO FREAKING WAY!!! I literally just saw a video talking about that clock the other day, and let me tell you, that thing is extremely rare and very impressive for its time! If it still works, then you’re looking at one of the most sophisticated clocks ever built! The minutes are indicated by the window on the bottom left, and the hours are on the strip at the top, which also denotes the different time zones. The middle part is a real-time day/night map that changes over time, depending on what areas of the globe are currently experiencing daytime or nighttime. And the whole thing is completely mechanical-besides the electric motor that powers it and the lamp, there’s no other electronic components in there!

[@ExitSign250]

No way! I’ve received a lot of comments about that clock/map. I’ve never seen one before and found it interesting. I’ll have to ask and see if it is planned to be removed. And if so I will attempt to preserve it!

They'll have put heat detectors in the bedrooms so people could smoke without setting the alarm off. Loved the video!

[@siphonralarms9411]

Okay, that is one awesome system! I’m a sucker for older alarm systems like this. My aunt’s old house use to have a 1970s Ademco burglar alarm system in it, though it didn’t have smoke or heat detectors since there were already 1990s FireX detectors hardwired into the house. The system had 2 arming stations (key switches) one next to the front door and one next to the garage door. Each door and window had a sensor in it and the hallway had an ultrasonic motion sensor. There was also a buzzer horn in the hallway as an indoor notification appliance, as well as an actual bell box on the outside of the house. The system still worked, but my aunt preferred to use the newer Napco system (Magnum Alert 1016) that was installed after she moved in back in the mid 90s.

[@ExitSign250]

Same here! They are so unique. Also that sounds like a neat system!

[@publicmail2]

I installed and worked on Dictograph, some early keypads where a joke, remove 2 screws and use paper clip to short the key wires, no tamper. The early smoke detector used a regular incandescent bulb for scatter emission, the bulb circuit was monitored supervisory and when burnt out 55-0 would annunciate buzzer.

My neighbor across the street from me had a similar but maybe a little newer system. I remember loud claps of thunder setting it off (heard an alarm bell outside). Also when painters were painting the outside of the house, they weren't aware of the outdoor key arm/disarm station and they needed to remove it to paint behind the plate as if it were a regular wall plate for a light switch or outlet, and later they were talking to the cops because they set off the tamper switch.

[@ExitSign250]

These systems definitely were sensitive and had issues. I spoke with the former owners of this mansion and they told me power outages often set off the alarm.

[@dieseldragon6756]

@@ExitSign250 On any system that's supposed to have a battery back-up, shouldn't triggering during outages normally prompt the owner to have the battery checked? The one in this system was _wayyy_ out of date by the time you'd removed it! 😇

[@ExitSign250]

With a fully functioning backup battery, the system will trigger after a power outage. However with a dead backup battery the system will not trigger after an outage. The instruction sheet on the inside of the control panels even says the alarm may activate after a power failure and it is a normal occurrence. To me this seems like a big flaw that should’ve been looked into.

[@wobblyboost]

@@ExitSign250 I feel like there was so many ways for this to trigger false alarms, including thunder, a bird flying into a window, a large moth flying by the movement sensors, bumping the prowler button, burning the toast, power surge, faulty contacts on pressure switches ... etc. They must have had to call the police to let them know it was yet again a false alarm quite often.

Very cool stuff. Interesting old system and house itself. I'm looking forward to seeing videos of this system.

[@larryu.4733]

The extra magnet on the window you noticed is so the system can be armed with the window opened slightly for air circulation. My Grandmothers house had this. The open window height isn't enough to climb through so raising or lowering the window any further triggers the alarm. The house also had pressure mats under the carpets and photoelectric sensors that looked like electric outlets. Cool stuff!

[@obeseperson]

Pressure mats under the carpets is crazy. That one almost sounds cartoonish but effective

Fascinating video for me. I am a well seasoned (old) security specialist from the UK, who has worked on all sorts of systems since the 90s. During that time, Ive worked on alarm systems which are much older than the house in which you are working, and of course many cutting edge high security systems. Ive always found the history of old such systems fascinating, even down to being able to determine whether the installation engineer was left or right handed based on the direction in which the cores are twisted at the control panel. Thank you for sharing this information. Without someone like you documenting it, it would be lost to time.

[@LITTLE1994]

For a vintage alarm system, this is actually pretty good.

[@Mpg-gh5fq]

Fascinating! My grandparents had a Dictograph burglar alarm system like this one in their house that was built in the early 1960s. Some of their windows were equipped with two sets of sensors so the bedroom occupant could have the window either closed or opened a few inches while the system was armed. You would have to put the window where you want it while the system was not armed, and then arm the system. It amazes me to look at vintage technology demos and see how a lot of the things that we think are new (such as a system that calls the police for you) have actually existed a lot longer than we might think.

[@daveash9572]

Having read some of the comments, im a bit amazed. I've worked on alarm systems older than this building in houses all over london. Admittedly, they are getting rarer and rarer these days, but there are still hundreds of them in every day use, in offices, shops, houses and factories all over the British capital. Some of the old systems ive worked on had normally open detection circuits, and some had normally closed circuits, but some very rare ones had a "flag cell" (essentially a large 1.5v alkali battery) located near to every door contact, usually tucked under the floorboards or in a cupboard, and these were there in order to send a voltage to the control panel, in order to energise a relay, one relay per zone. If the battery died, the cable got cut, or the door was opened, the alarm would trigger. Obviously very similar, yet very different industries in the uk vs north america. I even remember an auto dialler which I had to decommission, which relied on a wax disc record, on which I found a recording made by my predecessor, the installing engineer back in the 60s, saying "police, Scotland Yard, police Scotland yard" and went on to read out the address of the premises and that the burglar alarm had been activated. Totally illegal nowadays to do that, but fascinating to find.

[@jonzz100]

Interesting! Are these systems still working ok and in use? Are they afa or rely a bell, or, different? Do they only use door contacts? Am interested to learn more !

That is some pretty cool old equipment! My former eleme tary school had something basic like that, one green and one red indicator on a panel in the boiler room with nothing more than a toggle switch and "hold" button to arm it.... I had seen it done.... green light on you pushed and held the "hold" button, flipped the "arm" toggle, held "hold" for a few seconds and released.... You exited through a pre determined path out of the building. I hope if they are going to that extent to renovate they put in a proper security system as well as an actual fire alarm system, even if just conventional zoned and not addressable as well as one of those newer residental fire sprinkler systems. A house this size and this well built deserves that kind of protection.

[@danielstechclocksandmore]

It is by law for all USA schools to have a commercial fire alarm system

[@grayrabbit2211]

Correction: Some of these did have improvised stay/away modes depending on how they were installed. In some installs, they'd put a toggle switch in the master bedroom suite (bedroom, bath, closet) that would let you toggle on/off the rest of the indoor sensors, along with a keyswitch for the alarm to arm/disarm. On some newer systems, they did something similar, with instant / delay being owner-selectable by a toggle switch. Not true home & away "modes" but it did the trick

[@ExitSign250]

Yes there was a rotary switch where the control panels were located to select “Normal, Away, Night” modes. It was removed for some reason. You can actually see it inside of the burglary panel in this video.

Nice! That would make a lot of sense! I might try to recreate one, thanks for the tip!

[@aaronbrandenburg2441]

Yes agree and yes it looked me initially like a quarter inch phone number jack as well which makes perfect sense for a panic button on a cable. Also I have seen all kinds of systems some homemade and others not and had seen 1/4 inch photo Jax used for all sorts of things that probably shouldn't have been this type of Jack in some cases. For example one system actually had 120 volts on a quarter inch Jack believe it or not and a box that had a neon indicator and a push button switch this is not alarm system but I believe this was used to indicate that someone needed help or just Communications and also the bulb could be flashed in response and then really figure out how everything worked but it was rather interesting than the last needless to say that system was discombobulated on purpose and Salvage of course along with all the other interesting gadgets and gizmos in that place. Just goes to show never think something's low voltage until it's proven its low voltage. Always test never assume! And also there was one audio system type of thing believe it was for an old radio more than likely well on this Buffalo tension and high tension and other things were on wall plates with what looks like relay or tube on the wall plates and yes the full high voltage was present on some of these contacts and there was no interlock for disconnecting high voltage Apparently the high voltage power supply was always on. And still fully operational. Later found the rest of the system including the radio and there was also speakers that could be plugged in to the system that could even control the radio remotely and also control other speakers and this is also served as an intercom system one of a kind I've never seen anything like this before but probably something that existed back in the day but not common.

[@lesleybarnes7850]

I can confirm that it is a jack for a corded panic button. when we moved to our home in 1997, the Dictograph system here was fully functional and there was a 25-30 foot long cord that could plug in to any of the jacks and had a sort of bulb shaped end with a button in the center. Before the time of remote controls! We had the dialer as well, and another type of pressure switch not shown in this video that is installed on the basement entrance, which is a trap door.

The main control box is in the attic, but strangely there is no sign of any exterior or even interior key arming/disarming locks. A newer alarm system was installed after it and some of the older Dictograph parts may have been removed. Nice video! Keep up the good work!

[@dieseldragon6756]

The World Clock seen at 06:08 puts a *lot* of context on the setting, and explains exactly why the house had an alarm. I can still remember seeing an ad for those in the _Financial Times_ in the early 1990s, at that time priced around £3,000.- and up (About $6,000.- at prevailing exchange rates of the time) or - Adjusted for inflation using the Bank of England calculator - About £7,170.- ($8,970.-) today. I'm going to guess this was installed in the late 70s or early 80s (Germany's in two parts and Russia is still the СССР, so it's pre 1989) so perhaps around the time these started becoming a popular executive item. 🗺💰🕴 I can't work out for certain *what* the owner of this house made their money on (Whatever it was, it was sometime in the late 60s or early 70s, if the alarm install date is anything to go by) but they definitely made a *lot* of it. 💰🤑💰 You wouldn't have an alarm in a house where there were no particularly valuable items and possessions (Furniture, clothing etc) were something incidental to replace if they were lost or stolen, so I'd hazard a guess - Backed-up by the sumptuously paneled room - The owner probably had a collection of fine art or similarly valuable possessions. 💎 Also: The window vibro-sensor at 26:14 reminds me of a device that used to be employed here in the UK a lot, particularly by retail premesis; The glass break sensor. This took the form of foil loops bonded to the outside edge of window that would be cut if the glass was broken - Sounding the alarm - And those strips would be connected via springs to a device very similar to this one. If these were all hanging off wires and _not_ stuck to the window/frame, chances are the same approach was also used here, but at some point the windows were upgraded (Almost certainly to double glazing) and those loops were never reinstated, making those contact points redundant. 🪟 Either way: If that clock was also being taken out, I hope to goodness it's being preserved in a museum or caring home. That's a piece of geopolitical and electromechanical history right there, and it'd be a shame to see it lost. 😇

Interesting. My house still has remnants of an old fire alarm system that was installed in the 1960. In those days residential smoke detectors were uncommon so the system had thermal-detectors throughout thr house. All the bedrooms, thr boiler room, the attic, garage, etc. had thermal detectors . Most of them were set to go off at about 130 deg F but the ones in the attic were set to go off at 190 deg F since during the summer months the attic could get up.to.120-130 deg under normal circumstances.. The system had to be tesred at least once a month to make sure the backup battery was still in good shape and to assure that the system was functional. It used a bell, like the one in you video, as the annunciator should the fire alarm go off. The bell was located in the upstairs hallway near the bedrooms andnit was LOUD!!!.No way anyone would sleep through that. During the late 1970s and early 80s when single station self contained.smoke detectors became popular we installed those throughout the house and gradually the old system was decommissioned. For a while it was only active in the boiler room, laundry room, and attic. A couple years later it was fully decomissioned. Remnants of it still exist. Some.of the bedrooms still have the old heat detectors on the ceiling. Also the boiler room, garage, and attic still have the smoke detectors mounted although none are functional. Most are still connected to an old.panel via the old.alarm wire so at least in theory if I were to supply power to the system at least part of it might still work provided there are no open circuits or shorts . But since I'll be.moving soon I don't have the time to test it.

[@dang48]

Pretty cool! I had to do annual testing at one building where the client complained their attic heat detectors kept going into alarm when there was no fire. The heat detector heads, while restorable, were fixed temp. That was corrected by replacing them with rate of rise detector heads so when the attic warmed up in the morning with the sun rising, they could compensate for that increase in temperature while still giving an alarm if there was an actual fire.

Like one i set up they wanted it to roll down metal window covers, lock different doors, and it unlocked a back hallway that lead to a bunker. It would also text different phone numbers different text messages and let the owners decide if they wanted it to call 911.. the fire had different sectors and different suppression systems it could use based on what fire and where the fire was at. It had a co2 system, water and foam.. they had a library and a “show” room with a bunch of old expensive stuff and didnt want the stuff to get wet.. pretty cool system.. was a comm dial and gemani system.. the control box had a backup battery system that consisted of 12 24v batteries that were maintained with solar and the turbine spinny dudes on the roof.. that battery system was dangerous as hell being lithium. The gauge of the cabling it required was as big as my arm.. bigger than backup systems ive set up for hospitals.. some hospitals.. set up one that had 3 huge diesel generators.. those had some power.. everytime we would have to test em theyd explode at least one battery because they only used the lead acid and they degrade over time with non use.. the corrosion inside would cause sparks and the hydrogen they make when charged with the amperage they called for.. boom.. acid everywhere.. eventually we got the hospital to pay for enclosures so the acid wouldnt eat up everything.. good times.. got fired from that job for working too much overtime and not responding to a callout because had 2 supervisors. One said no more time on the clock and the other said to run on the call and clock in because i was working.. so they fired me for falsifying my timecard and insubordination for not obeying a supervisor yet they were the ones who changed my time card to show the extra hours after i already clocked in and they signed my initials on it.. as goes life..

Old technology like this were goated back in the day compared to new technology we have now. I love to see a demonstration video of that Dictograph 55 panel. I actually own one too, but has the red cabinet instead of a gold cabinet. Also, never seen those sprinkler head looking heat detectors before. I figured they use heat detectors that were shaped like harmonicas.

[@ExitSign250]

I agree, definitely robust stuff. If I’m not mistaken, the red cabinet variants of the 55-0 is the “commercial” version while the gold is the “residential.” The only differences between the two that I can find are the control switches; the rest looks identical. Yep those heat detectors are interesting. I’m pretty sure those harmonica detectors you mentioned are smoke detectors, not heat detectors. Perhaps they had a heat detector variant in the same housing. I know Dictograph sold those harmonica style smoke detectors early on, and at some point they switched to using/rebranding the Chloride Pyrotector smoke detectors like the one found on this system.

Very cool, and lookimg forward to the demo board system, especially to hear the unique horn in proper workimg order.

[@jonzz100]

Watched your excellent vid a few times again, noticed a few more points that interested me: There doesnt look to be any back up battery for the security panel, unless it originally went in the space under the circuit board. Theres no zone indicators, so the occupiers have to find out where it was tripped, if set at night for instance. I like the push button panels, very elegant and simple design, and there must be some clever 'relay logic' going on to switch the alarm on or off, as it looks like just a momentary contact push button. Theres a lot of indiator lights that I guess would be lit on each panel throughout the house when set. l ike the way the whole house perimeter is protected, to detect entry as early as possible, instead of detection after entry. There is a set of instructions and circuit diagram on the steel cabinet door, it would be interesting to see this in detail in any further videos....only just a few musings that occurred to me!

[@ExitSign250]

Thanks for your comment! I’m very happy you enjoyed this video. It was definitely a fun one to make and I looking forward to demonstrating the entirety system once it’s fully restored. The security portion actually does have battery backup. It actually runs off of the fire alarm panel. I will explain this in further detail in the second part once I have the demonstration setup completed. And yep, many relays are at play in this system. Pretty much the brains of it all! I did look into those documents on inside of the panels. They were very insightful on how the system operated. Yes there is no way to tell what device (fire or burglary) activated as it’s essentially one zone. But according to those documents there was an accessory you could buy that will indicate what fire alarm device activated. Pretty much just a big indicator light panel with labels.

I remember, my grandma‘s house in Germany, had a security system, and you would arm it with the key on the outside and disarm it with the key when you come back. When you’re inside, there is a button that you pressed, which would arm the system, and then I believe You would go down to the main panel, which was halfway down the stairs and disarm it that way, or when the siren went off, you would do the same. Didn’t call the police, it was just a noisemaker, so it probably is a lot older than the security systems that I’m used to today. The main panel downstairs also had a key to arm and disarm if you wanted. I believe the siren was on the outside, and the alarm on the inside was just a loud beeping or something. At least that is what I have been told. I have no clue what brand it was.

The “Elgin” box that was under that dialer is a telephone company coupler. It was required to have the telephone company install one to interface the dialer to the phone line. It did not call 911, it only allowed the dialer to dial out.

[@ExitSign250]

I figured it did something to that effect. However the Elgin box must be responsible for calling 911 as all the DictoDialer does is play a recorded message when activated.

[@himbeerme]

@@ExitSign250I think back then, telephone companies would not allow a third party device that can call something to be connected to a phone line, that's why early modems were using acoustic couplers. So it's probably a phone from the phone company that can only dial one number.

The spacing with the window contact is to keep the window open, yes, but youd open the window so the surface contact and mag are aligned.

It would keep that zone closed but have the window open still. We still do this today!

[@denisarbour3385]

The box called "Station Coupler" is actually some sort of phone line isolator. Several years ago, at least in Canada, it was illegal to directly connect to the phone lines any device (i.e. dialer) that was not provided by the phone company. A coupler (installed and leased by the TelCo) was required. Many TelCo installers did not even know how to connect them... all they did was run the phone line through it without any connection... The dialer actually took care of the dialing.

[@ExitSign250]

Interesting. I have heard from a few commenters about the “not being able to connect directly to the phone line” requirement. However the DictoDialer does not have the capability to dial. All it does is play a prerecorded message from a tape when activated.

[@chubbyadler3276]

I started thinking that the magnetic window switches were intentionally separated to allow the window to be partially opened when I saw them. I also figured they would be normally open insstead of normally closed like normal to allow it to be opened a bit. That was pretty much what you later found. ...though those glass breaks, I would be tempted to want to try an 18650 Li-Ion battery on, though I'm sure that a pack of AAs would work for testing. I also know we found one with no glass around, so my first thought when you started showing that one in the stairwell to the basement would be that it would be an ultrasonic sonar proximity detectors. Its placement in the starwell would have been so perfect for a sonar detector. ...though I wonder if those sonars would have been repaced every year or if they intended for the homeowner to remove them and carry them to a service center to have the battery changed.

I don't live there any more but it would be interesting to see how much of a difference insulating that attic roof would make.

That ultrasonic sensor is for short range motion and not glass. Ultrasonic detectors like that use high frequency sound that should not reflect back.

What is the panel cabinet key number? You show it as a Chicago cabinet lock, but NOT the actual key number. At one point in the video I paused and it looks like it is 2320, but I'm curious if this is what it actually reads on the backside of the key? Thank you for correcting in your comment about the ultrasound devices. The one located in the stairwell is the most smart location for such a device, as someone walking up the stairs would trigger it immediately as the 'echo' of the space would change. Curious what you find when you figure out powering them, and how sensitive to changes they are. As you may know already, defeating a passive infrared motion sensor can be done by putting a neutral temperature barrier between you and the sensor (bedsheets work great for this), however doing such to an ultrasound detector would make you -easier- to detect! The dialer is in fact the most interesting part of that system, as you state, that is spot on. There were commercial fire alarm systems in that era that utilized tapes for evacuation messages. Some of the early 'mass notification' systems, before we even had that term for them, utilized tape under the hood. I'm aware of one brand, Thorn, that even had an 'indexed' tape, so one tape held all the messages, and it would automatically 'fast forward' to the right one to play. I am curious if this dialer just used multiple tracks on the same tape to achieve this effect. Play track 1 for burg, track 2 for fire, or similar... The auto-dialer part of it was probably an add much after the fact, as doing an auto-dial on pulse dialed POTS lines was well within the purview of a small bit of relay logic. Only once touch-tone took off (DTMF) was actual full on electronics needed in order to auto-dial.

[@ExitSign250]

Thank you for your comment! I’m very grateful for viewer’s input on various aspects of this system and I’m happy to make corrections for anything I got wrong or need to clarify on. I will look into the lock and let you know. It’s definitely a unique looking key. With a bit of assistance from some viewers who have previously worked on older alarm systems, I was able to get the old motion detectors functioning. Both work great however one is more sensitive than the other. I believe there is a sensitivity adjustment on the circuit board, but I have not tried it out yet. Yep, I am so fascinated with the tape dialer. It is a single tape with two tracks. There are two inputs: one for fire and one for burglary. I’m looking forward to making a follow up video once I have the system fully restored and in operation. I will thoroughly demonstration each aspect of the system including the tape dialer.
