Air Products and Controls makes the interface hardware that connects fire alarm systems to the rest of a building — multi-voltage relays, sounder and relay detector bases, remote annunciation and indicator stations, and duct detector housings and accessories.
These are the parts that solve integration problems: shutting down an air handler on alarm, releasing a door holder, driving an auxiliary function, or bringing a remote indication somewhere staff will see it. Relays are selected by coil voltage and contact configuration; bases are matched to the detector family they carry.
