I think it's normally closed for supervision reasons. If it was hooked up to a relay exactly as you did, the alarms would start ringing when a wire got disconnected. I think the other NC contact is for "non interference", where each pull is wired through both the alarm contact and NC contact in series, so if two go off at the same time they don't code over each other. I think the lever inside also has something to do with this. Maybe different models had an electromagnet to pause the station while others were going off, so each would do its full round of coding. I know many Gamewell Master Boxes have that feature, and there is at least one video showing it off on youtube. Great video!

How to link two conventional Panels?

3:57 It sounds like 1 of those cheap toy fire trucks Probably what they used for the sound, 4:03 Sounds like the Canada emergency alert sound, 4:11 Some very high pitched police are coming after the product,

I took apart my advance because there was a bug in my strobe lens

What if I forgot password?

The ones with the bubble on the strobes are 15/75 candela. The one you have without the strobe bubble is just 15 candela

Guys I think he died

sometimes I wonder if any church fire alarm sounds every stop in a pipe organ

How can i restore the password

The fake one gives me a weird reaction

The L-Series 3k tone sounds like a smoke alarm

This one was manufactured in 1996.

All tone

No water for fire alarm

I have the same one but mines is white and has the wmt strobe

Best review video I thought the March time was pulse though.

The P2R is very common in Kuwait 🇰🇼

We have these in Saudi Arabia 🇸🇦 Qatar 🇶🇦 and Kuwait 🇰🇼

That’s ear piercing. I want those kind of fire alarms!

The tones of the alarm would battle if the Classic was on Filtered DC because the Electromechanical horn tone and the 3K Interrupted tone on the Classic have the same pitch has perceived to the ear, however the tone will produce a beating frequency because of their different programed frequencies as the L-Series on 3K will produce a beating frequency sound with the Classic on its Electromechanical horn and 3K Interrupted tone. This doesn't happen with the L-Series on its Electromechanical horn tone because it's a frequency sweep broadband sound that changes its frequency in a frequency bandwidth at a very fast rate which avoids interference as the tone isn't constant and instead moving in frequency to avoid interference with another tone and this is also just like in FM Radio as it sounds better and less prone to interference than AM Radio

Will that work with other 2-wire fire alarms or just the EST Genesis?

02:28 "Uh oh let's take this fire alarm device to the dentist"

Does it need a relay to work?

How do you put on the bracket?

i got everything setup correctly but the speaker terminals aren't outputting anything at all. used different speakers, swapped the wiring on the speaker terminals and yet nothing. I bought another of these boards thinking it was defective and turns out both are giving the same issues; however, sound is coming out from the headphone jack. Pls help!!

disapointingly quiet..

the arsenal mall used to have these on rectangle plates I’m guessing originally they were space age fire alarms like Marshalls still has though probably disconnected since newer alarms replaced them

I got an mp3 like this with 9 triggers and “lamp” terminals which could be used standalone for your NAC. I’m making a panel using just that without anything needing programming

Were the extra stickers put on by you or did the company that ripped off the Spectralert put them on? I just want to know. The stickers with “Fake”, “Stolen”, U m m m Is this even legal” and another “Stolen”. I just want to know.

is it addressable

Dissasble wheelock AS

maybe something like this would be approved in a small building

Will this work on the Ms 4?

Thanks

Do you know of any way I can safely muffle / reduce the volume without completely disabling the unit in my apartment? Excessively loud!

*XMAS* Alert

Can i have?

Wheelock AS next

The way bro smashed it

If I connect a wired phone to the speaker output terminals, would it broadcast to the speakers as long as audio isn't playing? I have an old Autocall-Grinnell MCM-500 module that would be neat to hook up.

Is there a way to decrease piezo volume? The piezo on my ES-50X makes my ears bleed

Will you ever be back?

I also have an old Edwards system still in my home, probably dating back to the 70s. A bit different than this one, don’t know too much about it. Moved here in the 90s, and it’s kind of always been there, does buzz a bit since it’s old and probably outdated. Would love more info on it

Can you hook up multiple speaker strobes?

Can you use this without a panel?

You good?

Classic UMMT

Coming back to this video, these will work with addressable panels, at least on the MS-9200UD. You will need a monitor module for each channel on the relay board. So that’s a total of 4 monitor modules supervising each triggerable channel.

So on Coding can you set the power up and do that signal and then it will do that signal or does it require a panel?

I bought one of these, it just included the panel, I was wondering if anyone has scans for the manual, and what type of diode it uses, as it includes neither of those, and also what types of devices hook up to it. when plugged in it makes a noise and the test button works, but I think I need devices for it and the diodes.
