Simplex Fire Alarm Code 3

[@IanGSully]

It's nice that they retrofit the system, and still keep the pull rod, as well as add pull stations.

[@IanGSully]

To be honest, I am not sure if the system is original to the building.

[@metersocket00]

I love old institutional buildings (grade school/college and hospitals), the fire alarm systems, boilers, and old electrical systems are fantastic, it’s too bad that after they’re decommissioned they get torn down. There is an elementary school by where I live built in 1926, and because there are cookie cutter houses going up like crazy, there is a new one being build as a replacement. I think it would be cool to buy an old building like that and re-purpose it into an office building.

[@FEDERALSIGNALTECH]

The old SIMPLEX 2901-9838 horns are music to my ears just hearing that really makes me feel like I'm in school again even though my high school didn't have that particular horn but just hearing the same signal brings back memories of my time in school.

The 4002 is an amazing panel, it’s sad that these things today are being replaced with Honeywell or EST systems. There is a primary school which as of this comment being written is being removed and possibly thrown out, I do know someone that works for the district who might save some of the old alarms and pulls and even the panel if there is a way. I feel like the old alarms are better than newer ones, they get your attention real fast, they are also very low pitched. High frequency alarms do have a slight flaw, some are so high pitched that old people probably can’t hear them, I don’t know if that’s true, but older is better.

[@OldSchoolFireAlarms]

I agree with you 100%. The older systems are better then the cheap, junk that is manufactured today.

[@firealarmtechguy4444]

Personally I think the EST IO series and most Simplex is decent but nothing beats the old tank 4005 and 4002!

[@ryguy2006]

Very interesting! I liken the pause to that of a GOS on chime. Also, it's interesting to see this kind of combination.

[@ieuuuu]

My secondary school is older than this, when I went there on my like taster day there were some old fire alarms but on my 1st day the system had been replaced with Apollo open air sounders.

[@WheeloveFireAlarms]

That's awesome!

[@NotBrainy]

Surprised your here, and yes its awesome!

[@The09creeper]

Definitely a surprise

[@brettman273]

Ah the 4002...big old monster, those things. Still have 3 or 4 active in inspections I do. A few notable details about the 4002 (and 4001) that I have encountered: The nature of the zone circuits is such that there is a delay upon tripping one before the zone will go into alarm...about 2 seconds. So...pull a pull station, unlock and reset it fast enough and the alarm will not trip. Hence the sign that says "Hold for three seconds" by the pull rod. Can't say for sure but I think the reasoning behind it is that smoke detectors of that era were much more prone to falsing, and the simplex ones like to trip rapidly on and off when the smoke level is lower than it should be...or dust is present. So this delay allows for that to happen and not trigger nuisance alarms. Just a guess. The other tidbit is the fact that the temporal/code 3 circuit in this is not quite "correct" in that the sequence time is slightly longer than the ansi standard 4 seconds (+/-10% - works out to 3.6-4.4sec). These are just shy of 5 sec...and I possess this useless knowledge due to having had to deal with it in the field. Long story short: young new town fire inspector flexing his muscles because he could decided to take issue with me passing one of them for this reason. The complex bureaucratic mess that are codes, standards, etc is one that can be endlessly nitpicked but these panels were produced in the late 80s and early 90s; Temporal 3 was standardized somewhere around '96. That fact means it doesn't matter than it cannot produce the "correct" output...as long as it still works it is grandfathered in until it dies. That was my argument against failing it. His was that since it was set to code 3 it had to be "correct". My response? Changed it to march time and passed it again. Awaiting their response.

[@MircomFan]

lmao, yeah any system I deal with that was made before '96 I leave the coding the way it is. Most fire inspectors here don't really care much. Plus we don't ever fail panels for that reason, only if they truly don't work, or we have to upgrade elevators, which has been a big factor in the many systems we've replaced this year. We do 2 that I know of, one in an apartment building, and another in a commercial complex, both set to continuous.

[@QuikCall4623]

The 4002 Temporal Code 3 Pattern is .5 On /.5 Off / .5 On /.5 Off / .5 On / 2.5 Off

[@RedSkylinex60]

Does anyone know if other pre 1996 panels besides the 4001/4002 also do code 3 this way?

[@ZakWolf]

It appears the Simplex 4002 system was initially audible-only, and then additional horn/strobes were installed in the 1990s so it could be an audible/visual system. Now what I'd REALLY find interesting to see is a very modern fire alarm system (something like one of the new Simplex panels) tied into an old manual pull rod system, with the modern electronic horn/strobes. That would be a cool mix of old and new fire alarm technology.

[@OldSchoolFireAlarms]

Any new, modern day fire alarm system can be tied into a manual pull rod system by using a micro-switch that is similar to the one in my video, The Invisible Pull Rod Fire Alarm System. If you haven't already, check it out. There are various ways of attaching the micro-switch to the pull rod to activate any modern, automated fire alarm system regardless of the brand/company.

[@ZakWolf]

Neat! If I ever see a setup like that, I will let you know.

If this was the original Autocall system in this video, would the trouble bell on the control panel be heard from where you just pull in that particular angle and the bells would be resonating?

[@OldSchoolFireAlarms]

The control panel was a Simple 4002 , not an Autocall. So there were no trouble bells. The original Autocall control panel was removed and replaced with the Simplex panel sometime in the 1980's.

[@sigglass2183]

Oh, are you thinking to do a tutorial on that particular school soon like you do with most of them with the talking?

[@trainerred2063]

What’s your opinion on DC mechanical/vibrating horns (as in the 9838s in the video or something like 4051s, Federal Signal Vibratone 450 series A1 or B2)?

[@OldSchoolFireAlarms]

I think they are great horns. They are constructed well and are loud. When you hear them go off, you know it means FIRE, GET OUT!!

[@trainerred2063]

Old School Fire Alarms nice. Personally I prefer DC mechanical horns by a SMALL margin because of their easiness to power, keep running with new panels, and varying pitch.

[@NVHSChadSheppard1]

Did the old autocall system had single stroke bells or horns?

[@OldSchoolFireAlarms]

This particular school never had an Autocall system. It was originally outfitted with a Reiter, manual pull rod fire alarm system, then in the 1980's it was upgraded and automated with a Simplex 4002 fire alarm system.

[@Doubled-iu4cb]

[@OldSchoolFireAlarms]

No, this is a different school.

[@sigglass2183]

Was there another fire alarm system in that particular building before Simplex was installed in the 80s?

[@OldSchoolFireAlarms]

The original system was the Reiter, manual pull rod fire alarm system with an Autocall control panel that was installed in 1956.

[@sigglass2183]

did they replace the system because the b or j relay didnt work on the autocall panel?

[@brettman273]

Saw a few comments proclaiming the horns as mechanical, not electronic. Horns from this era are indeed electromechanical in nature; however, take one apart and you will find an electronic driver circuit that uses optical feedback to dramatically amplify the sound output and at the same time not use nearly as much current as the electromagnet doesn't need to be as strong. Without the electronics involved, these would not produce the necessary level of sound output. I discovered this by accident when attempting to use one with a microcontroller to produce music and it sounded godawful. In the process of trying to figure out why I found a patent for the circuit which had a schematic. And of course I can't find it now to link....sigh.

[@OldSchoolFireAlarms]

You are absolutely correct Brett, the horns are Simplex model 2901-9838 and they are electromechanical in nature. As time marches on, it is so interesting how fire alarm hardware keeps changing.

[@RaccoonAlarmsVosgra]

Could you get in trouble for pulling alarms out if abandoned buildings

[@OldSchoolFireAlarms]

Yes, you must get permission from the owner(s) of the building(s) before removing any property within the buildings. If you do not, you could be charged with trespassing and theft.

how do these alarm sync

[@OldSchoolFireAlarms]

The pull rod is wired to a micro-switch. When you pull the rod, it triggers the micro-switch which then sends a signal to the master control panels that sets off the horns and light strobes. Thank you for watching and for your question.

Hello Frank, if you examine the horns closely, the horns are in fact electromechanical in nature. When taking the horns apart, which are model #2901-9838, you will find an electronic driver circuit that uses optical feedback that helps amplify the sound output.
