And of course that was before that time they installed the new Simplex fire alarm panel at your high school, and the first time they did a drill with it, it sounded most of the alarms on Code-3! (The Simplex 4903+9838 horn/strobes, 4903-9219 horn/strobes and older SAE 2DCD+AV32 horn/lights?) At least at Massasoit College they had no trouble switching to Code-3 in buildings using electronic horn/strobes!
With the thread bump, here’s another one; a small apartment house not too far from the abandoned Howard pre-K school in my hometown; they have a Silent Knight system that isn’t monitored, with at least one or two Wheelock MT-24-LSM horn/strobes on Continuous, Adaemco-branded Sigcom T-bars and some kind of System Sensor/ESL smoke detectors. I actually heard it going off one day when I passed by, and noticed no fire alarm company trucks or whatever. I didn’t see any smoke or flames but I still did the right thing by calling the fire department! It turns out a lady was cooking on the top floor and the smoke tripped a detector in her apartment, and she couldn’t hear the alarm from where she was! (The fire department did agree that the system does need some fixing up, such as heat detectors in the kitchens instead of smoke, and probably another horn/strobe on the top floor.)
