Nice system? Why different detectors though?
Nope. My only guess is the Fenwals being there first and the TrueAlarms coming later, but there’s two Fenwals near each other, so idk.
Yeah: there being two smoke detectors side-by-side in multiple places doesn’t seem to make sense.
Probably a 90’s Simplex (and maybe Fenwal?) originally, and some got upgraded in the 2000s or 2010s for the TrueAlarms. I don’t know the history on the building, so I can’t say for sure.
My high school has two detectors (both smoke!) on the same ceiling tile in some rooms. They only do this in rooms that aren’t sprinklered, and in the science classroom.

Yeah, but that doesn’t really explain why in either case there’s more than one detector does it? (aside from maybe in your case one being a heat detector & the other a smoke detector)
And the fact that my school is sprinklered and has heat detectors in the cellings?
I wonder if it was originally built (or alarmed) before ionization-type system detectors were phased out, so they had one ionization and one photoelectric detector in a cross-zoned/coincidence setup in those rooms?
This seems like the most plausible explanation.
Here’s a picture i took today. Sorry it’s a little blurry because I had to zoom in.
You can see the two SIGA detectors right next to each other, and the ALERT marked genesis speaker strobe.

Well in that case the one detector might be a CO detector going by a video of a similar system.
They are both smoke detectors, both have the same markings on the smoke head that indicate they are smoke detectors.
Oh, okay. Odd then that there would be two side-by-side like that though.
University of Hartford neighborhoods housing. System was likely upgraded to a 4100U, a lot of the system was replaced with true alerts (some new installs many on retrofit plates), outdoor Weelock MT, one outdoor AS, newer addressable pulls, true alarm smokes and heats. Some buildings have original parts of the systems still in use or abandoned in place. The system was likely replaced 3 times as there’s what I believe to be a 4040 horn also outside. Oddly some of the true alerts in the basement don’t have simplex or true alert text on them.
I have a picture of a brandless QuickAlert but I forget where I took it, somewhere in Knoxville iirc. It was a remote strobe though.
AMERICAN DREAM MALL, Rutherford NJ.
This might be a HUGE Simplex 4100ES system, Simplex Speaker Strobes for the whole mall, The Dreamworks Waterpark has Wheelock RSSP Strobes, and it overrides the pa system if the system goes off, The garage part of the mall also have rssp remote strobes, and also have TruealertES speaker strobes, they also use atlas remote speakers in grey with the RSSP remote strobes. in the nickelodeon universe park, they have simplex truealert remote strobes, and they override the PA system like the waterpark.
Why do the parks only have remote strobes?
The PA system probably plays the evacuation message.
Dang…would have been a heck of a unique combination to save, & in such excellent condition too! Thought about asking whatever service company did the replacement if they still happen to have the old devices & if they’d be willing to give them to you?
