Kidde - Edwards 1508-AQN5 Magnetic Door Holder 24V

Product Description

The KIDDE - EDWARDS 1508-AQN5 is a surface-mount magnetic door holder designed for fire alarm and life safety systems. It holds fire-rated corridor doors in the open position during normal building operation and releases them automatically when the fire alarm system activates. The unit operates on 24 volts AC/DC or 120 volts, giving installers flexibility in power source selection. Licensed fire alarm technicians and electricians install this device as part of a compliant door control circuit. It mounts directly to wall or baseboard surfaces without recessing into the structure.

This door holder is used in commercial and institutional buildings where corridor or stairwell fire doors must remain open for traffic flow but close automatically upon alarm activation. Typical applications include schools, hospitals, office buildings, and multi-family residential facilities subject to NFPA 72 and local fire code requirements. It is sold individually and suited for new construction and retrofit installations where surface mounting is the required or preferred method.

Installation Notes

Installation should be performed by a licensed fire alarm technician or electrician in accordance with NFPA 72 and applicable local codes. De-energize the fire alarm control panel circuit and disconnect power at the source before wiring the device. Verify the supply voltage matches the intended circuit before making connections. Coordinate door holder placement with the door swing and wall surface to ensure proper magnetic contact with the armature plate on the door.
