Detex EAX-300 Black Door Prop Alarm Surface Mount

Product Description

The DETEX EAX-300 BLACK is a surface-mount door prop alarm designed to alert personnel when a door is held open beyond an acceptable dwell time. Battery powered, it requires no hardwired electrical connection, making it suitable for retrofit installations on doors that lack conduit access. The unit mounts directly to the door surface and sounds a local audible alarm when the door remains open. It is installed by security contractors, facility maintenance technicians, and commercial door hardware specialists.

This alarm is used on commercial and institutional doors where unauthorized propping is a security or safety concern. Typical applications include stairwell doors, emergency exit doors, loading dock entries, and back-of-house access points in commercial buildings. The black finish allows it to blend with darker door hardware schemes. Because it is battery powered, it can be installed without disrupting existing door hardware or electrical systems.

Key Features

• Surface-mount design installs directly on the door without frame modification
• Battery powered operation eliminates the need for hardwired electrical connections
• Local audible alarm activates when door is propped open
• Black finish for compatibility with dark door hardware

Compatibility

Designed as an OEM-style surface-mount door prop alarm suitable for commercial and institutional door applications where a battery-powered, non-hardwired alarm is required.

Installation Notes

Installation is typically performed by a licensed security technician or commercial door hardware installer. The unit mounts to the door surface using mechanical fasteners included or specified by the manufacturer. No electrical shutoff is required due to battery-powered operation, but installers should verify battery installation polarity before mounting. Follow all applicable local fire and life safety codes governing exit door hardware and alarm devices.
