r/firealarms

Customer called and complain about intermittent trouble that keeps going on and off for few days now. It’s a Siemens fire panel. The trouble shows “2nd floor mechanical room Duct smoke malfunction trouble” and “IN Input source malfunction” and “Out Input source malfunction”. It comes for few minute and disappears for hours. Any advice is appreciated. Thanks in advance 🙏🏻

Seems Gentex made a new mounting plate for the speaker-based Commander 5 alarms, which included the LF sounders. While this may not affect new installations, you might want to take this into account if you need to replace any of the xenon-era LF sounders.

On FCPS was faulty but the wire management was a disaster. New set up is clean and no wire nuts were involved with the new setup.

Maybe this is the wrong place for this, in which case I'm sorry. I'm putting in an addressable system into my house with a silent knight 6700. Basement is gonna be wired with all slc loop and part of the first floor, and the rest all swift wireless devices.

I have these antique "pull stations" that are the same ones used in the high school I used to attend that was very old. I thought it would be cool to convert them to addressable with modules salvaged out of addressable bg-12's and to drill a hole in the metal plate behind the break glass, and mount the polling led as a panel mount led, so you can see it polling through the break glass. The other option of course is to use monitor modules, I just thought this would be cool, but would this be considered a shame or bad to modify these antique devices?

EDIT: Thank you guys for your input, I will do it, I feel way less bad about modify antiques.

Walking through a mall in China, and I began to notice something off with the fire alarms. They are made by Siemens, but they look like a fake Spectralert Classic.

Hello! I volunteer at a small museum and in our storage we found a Morse code fire alarm. I would like to get it up and running so guests can see how it works. Now I’m no electrician so I don’t know if it takes dc or ac and if I could damage the mechanics inside if I pick the wrong wires at the bottom. The center silver wheels teeth are the firebox code and its hits on the brass to its right to tap the message. the black handle winds it up and white lever is it’s on button basically. From what I’ve seen online it’s was probably connected to the grid and another wire went straight to the firehouse. Any advice or help would be appreciated! I also have a video of it working so feel free to message me for that or other questions! Thanks!

Old Morley panel on site a few weeks back. Safe to say its had it lol

Rode along for a service call after an inspection. This waste management facility has a Spectronics 640 panel!

This location has a recurring issue where the panel would alarm whenever it gets very hot. Considering the heat wave here in the northeast US, this was somewhat inevitable.

The alarmed zone is a processing building that has mechanical heats. They should be the high temp models (194F), but couldn't determine if that was true.

With the heats being way up high and wiring all over the place, we just strapped out the zone with an EOL to get it normal. The service department will take a look at a later date.

For anyone curious, this facility has Notifier LNG-1R pulls and Wheelock AS/MT horn/strobes.

I am currently new to wiring fire panels and I’m trying to wire this to a MAX2 wireless communicator panel. I have no help so I’m pretty lost lol. here’s an image of the wiring I drew up. Would I need an rj45 to only two leads to the ifp 300’s phone terminal?

Saw this new alarm in a McDonald's today, never seen it before but the device looks brand new and an LED. The speaker/horn also looks interesting circling the strobe like that. There was a ceiling version in the bathroom that looked cool as well but I don't have a photo of that one
