I was at the Showcase Cinemas in Randolph, MA today to see “Toy Story 3” with some friends. I paid a bit more attention to the alarm system when in the lobby, so now I know more about it:
The cinema has a Simplex 4100 voice-evacuation system. The main panel was showing a “SUPERVISORY” condition (they said that they always keep it that way when the theater is open; is this even legal?), and it had an emergency mic and telephone on it. Next to it was a 4100 auxiliary panel.
The signals were Simplex 4903-9168 speaker/strobes (I saw through the grille), and the pull stations were 2099-9761 dual-action T-bars, many of them behind Stopper II covers.
The smoke detectors were Simplex TrueAlarms; many of them were the older version on the smaller base. But there were a handful of newer TrueAlarm smokes as well, and the restrooms had the heat-only version. They were all addressable.
