So earlier today before school, I noticed a fire alarm technician removing some of the alarms at my apartment complex. I told him about my hobby, and he gave me 2 devices, a System Sensor 2100, and a PA400R. So after school, I decided to check the dumpsters for alarms, and I was able to salvage all of this.
Love the holes drilled into the front of the 4424. Alarm goes off? Just have some random idiot silence it so everyone can go back to sleep. That’s why when I see broken locks on panels in apartment buildings I write it up as a deficiency.
Yup. All of the 4424s in the system had holes drilled in them. Idunno where the 5024 came from.
Maintenance guy probably got tired of going out there at 2am to silence troubles and alarms. Gotta love maintenance guys!
If those are gone, what are the new alarms? Assuming mini horns were in the units and the SpectrAlerts in hallways?
The Spectralerts were in the stairwells (outdoor btw) and the PA400Rs were in the units.
The panel actually wans’t even on before this happened. It wasn’t a maintnence guy either. Rather dissapointed on how the technician treated the alarms. He removed lots of them by just snapping off the parts of the alarm that covered the screw, then took it out.
So what were the horns replaced with? Let me guess? SpectrAlert Advances right? :roll:
Nothing yet, actually. He just took out the alarms and left. Might be L series, or maybe even Genesis. No clue.
The demolition people at that old school removed the entire plastic housing of a 4251-30 they gave to me and the other was so badly damaged I just kept it. Although most of the damage was done by the vandals that broke in throughout the 25 years the property was closed and sitting there until they put a fence up around it. Mostly all of it was in extremely good condition though and works fine! I’m sure you can clean some up. Not sure about mounting though. Great finds though.
You can purchase new mounting plates from eBay, I’ve seen plenty of them, but make sure they are the screw in ones NOT the Quik Clik…as for the tabs, you’re out of luck there
Yeah, when you demo, you aren’t really too worried about them coming out clean. Time is money, plus it’s fun to break stuff!
So true.
Well if they do get the L-Series, se if you can convince them to use the non-default tone. 
I wouldn’t recommend it since this is an apartment building, which means the fire alarm system might have to wake everyone up if there is a fire in the middle of the night, and 3100Hz sucks at waking up people, which is why 520Hz low frequency sounders were invented, and while it’s very unlikely this building will get those (they aren’t required for retrofits or outside sleeping areas), the electromechanical tone will probably still be more effective at waking up people than 3100Hz. It’ll also prevent the main fire alarm system from being confused with a domestic smoke detector.
