I'm a fire alarm enthusiast who collects many unique, rare, old, new etc fire alarm devices. I'm also a bowler, and a railfanner. My interest in fire alarms started in July of 2014, when I started noticing them in many buildings, and I have been interested in fire alarms since. My interest in abandoned buildings started around 2013, my interest in bowling started in 2016, and I have been interested in railroad crossings and trains since I was 4 (2005). I upload a video when I have the time to do so.

Update: I changed my youtube name from Nicholas Anselmi to Fire Alarms of Long Island NY on March 19th 2021 after moving my videos, comments, etc to a brand account with the Fire Alarms of Long Island New York name.
When you hear a P2RL going off in person, it actually sounds somewhat less harsh than a SpectrAlert Advance. One such system I heard going off from nearby I noticed it sounded like Advances but something seemed "different" about the sound, and sure enough they were L-series horn/strobes.
COOL! I think thesdx had a Honeywell branded version of this horn. I don’t know if it was polarized, but it sounded at the same frequency as this horn.
Never test your own fire alarms in public buildings because it can cause confusion and a potential evacuation when they see it and you can go to jail for doing so
I'm still looking for a light plate of that exact type, with the horn sticking out a bit and the older light circuitry. My first elementary (now K-8) school had that exact same configuration, built in 1974. But when their old Simplex 4208 panel began failing in early 2015, they dumped Simplex and had all the old alarms junked and replaced with boring SpectrAlert Advance horn/strobes (they even replaced the Wheelock MT-24-LSMs in the modular building with Advances!)
