I found out what the fire alarms are at the Bat Bus Transfer Center. They are Simplex 4903-9236s. I can tell because I peeked through the grille and saw the electronic horn type of thing, and it has the larger “S” logo and it has the 15 candela symbol on the strobes. They are powered by a 4005 panel with dual-action T-bars (Simplex 2099-9756) and wiffle-ball -style smoke detectors, like the kind at NewAgeServer’s middle school. The men’s room has a Gentex horn/strobe and the parking garage has Wheelock AS horn/strobes and “generic” Adaemco T-bars (relabeled as Simplex).
