The Kidde 1504-AQN5 is a flush wall-mounted electromagnetic door holder built for fire-rated door assemblies. Multi-voltage operation (24 VAC/DC and 120 VAC) means it powers off whatever's already available at the door - no dedicated transformer needed on most jobs.
Built for the commercial installer
Mounts on a standard single-gang (2 x 4 inch) outlet box for fast, clean installation. UL and ULC listed under R6291. Fail-safe design releases the door automatically on power failure or fire alarm activation, keeping the building code-compliant without additional relay logic.
