Fire Alarms in Buildings (2.0)

Today I went to the Boston Foundation building in Boston, MA for my Transitions to Work graduation ceremony. It has a Notifier voice-evac system of some sort (no surprise, given Honeywell is rather common in Boston, along with EST and Simplex.) There was an LCD-80 annunciator in the main entrance, which suggests this may be a late 1990s/early 2000s system. The alarms were Wheelock E70 speaker/strobes, and the pulls were NBG-10LXs. (I wouldn’t be surprised if there was at least one NBG-12LX somewhere in there too.) There were also System Sensor 2451 smoke detectors (probably the addressable Notifier version), along with a few FSF-751s and at least one FSP-851 detector.

There is also a Five Guy’s burgers and fries restaurant I like eating at in Boston that has a Gamewell system of some sort, with a late 1990s/early 2000s Gamewell annunciator at the main entrance (prior to the FCI merger) and Gamewell Century pulls rebranded by Easton Electronics with Stopper II covers. The unusual part is the signals used: multi-candela Simplex TrueAlert horn/strobes! I am not sure how this happened, but I have a couple of theories…

  1. The place may have originally had a Simplex system, but they upgraded and kept the existing signals.
  2. At one time they had Wheelock signals or similar, but after they made the place a Five Guy’s, the TrueAlerts were installed because Simplex probably did the alarm job (it was made into a Five Guy’s not too long ago, actually.)

The Arlington MBTA Green Line stop also has a Notifier system, not surprisingly, with NBG-12LX pulls. But what’s unusual for an MBTA subway station alarm system is the signals used: Wheelock ZNS horn/strobes! Usually I see Wheelock AS or MTs in those subway stops…
