Kidde 1505-AQN5 Semi-Flush Door Holder Fire Alarm Device

The Edwards 1505-AQN5 is a semi-flush wall-mount door holder designed for use in commercial and institutional fire alarm systems. It is engineered to hold open doors that are required to release and close automatically upon activation of a fire alarm signal, supporting orderly evacuation and compartmentalization of smoke and fire. The semi-flush wall mounting profile allows the unit to integrate cleanly into finished wall surfaces, making it well suited for corridors, stairwells, and other high-traffic areas where a low-profile installation is both aesthetically preferable and practically important. When the fire alarm system triggers, the holder releases the door, permitting self-closing hardware to function as intended and helping a facility meet fire and life-safety code requirements. Professional installers value this type of device for its straightforward integration into Edwards fire alarm control infrastructure, its clean finished appearance once installed, and its role as a reliable, code-compliant component in a broader life-safety strategy.

Key features & benefits

• Semi-Flush Wall Mount Design — The low-profile mounting configuration sits close to the wall surface, minimizing protrusion into the path of travel while maintaining a clean, professional appearance in commercial and institutional environments.
• Automatic Door Release on Alarm — Upon receiving a signal from the connected fire alarm system, the holder releases the door immediately, allowing it to close and perform its fire and smoke barrier function without manual intervention.
• Life-Safety System Integration — Designed as part of the Edwards fire alarm ecosystem, the device is intended to work within a supervised system architecture, supporting coordinated response across a facility during an alarm event.
• Suitable for High-Traffic Locations — The holder is appropriate for corridors, egress routes, stairwell entries, and similar areas where doors must remain open during normal operations yet close reliably in an emergency.
• Code-Compliant Application — Door holders of this type are a recognized means of satisfying fire and building code requirements that mandate automatic door closure upon alarm, helping facility managers and contractors meet inspection and compliance obligations.
• Professional-Grade Construction — As a genuine Edwards product, the 1505-AQN5 reflects the build quality and reliability expected of components installed in life-safety systems that must perform dependably over extended service life with minimal maintenance.
