The DETEX EAX-300W GRAY is a surface-mount door prop alarm designed to alert personnel when a door is held open beyond an acceptable dwell time. Battery powered and weatherized for outdoor or semi-exposed environments, this unit mounts directly to the door or frame without requiring hard-wired electrical connections. It is well suited for commercial and industrial facilities where exit doors, stairwells, and utility access points need to be monitored without a full access control infrastructure. Security integrators and facilities maintenance technicians are the primary installers.
This door prop alarm is used in commercial, institutional, and light industrial applications where unauthorized door propping is a security or safety concern. Typical installations include exit corridors, loading dock doors, rooftop access hatches, and exterior utility entrances. The weatherized construction makes it appropriate for locations exposed to rain, humidity, and temperature variation, including covered exterior doorways and partially sheltered openings.
Designed as an OEM-style surface-mount door prop alarm suitable for standard commercial and industrial door applications where a battery-powered, weatherized alarm is required.
Installation is typically performed by a security technician or facilities maintenance professional. The unit mounts to the door surface or frame using standard fasteners with basic hand tools. No electrical shutoff is required for battery-powered units, but ensure the door is in the closed and secured position before mounting to confirm proper alignment of the alarm trigger mechanism. Follow local building and fire codes regarding exit door hardware and alarm devices.
