Detex EAX-300SK4 Gray Door Prop Alarm Surface Mount

Product Description

The DETEX EAX-300SK4 GRAY is a surface-mount door prop alarm designed to alert personnel when a door is held open beyond its intended dwell time. The unit runs on battery power, eliminating the need for hardwired electrical connections and simplifying installation in locations where conduit runs are impractical. Two MS-1059S magnetic switches are included, providing reliable door-position sensing without mechanical contact wear. The gray finish suits standard commercial and institutional door hardware environments. This type of device is typically installed by security integrators, facility maintenance staff, or licensed electricians working on access control and egress monitoring systems.

The EAX-300SK4 GRAY is suited for commercial and institutional applications where unauthorized door propping is a security or code-compliance concern. Common install locations include stairwell doors, emergency egress doors, server room entries, and loading dock access points. The surface-mount design allows the alarm body to be fastened directly to the door frame or adjacent wall surface without mortising or cutouts, making it practical for retrofit installations on existing door assemblies.

Key Features

• Battery-powered operation eliminates hardwired electrical requirements
• Surface-mount housing simplifies retrofit and new-construction installs
• Includes two MS-1059S magnetic switches for door-position detection
• Gray finish for compatibility with standard commercial door hardware aesthetics
• No mechanical contact points on the magnetic switches reduces wear over time

Compatibility

Designed as an OEM-style surface-mount door prop alarm for commercial and institutional egress door applications where battery-powered, self-contained alarming is required.

Installation Notes

Installation is typically performed by a security integrator, locksmith, or licensed electrician familiar with access control and life-safety hardware. Verify that the door and frame geometry allow proper magnetic switch gap alignment before fastening the housing. Power down or remove the battery before wiring the magnetic switch leads to the alarm unit. Follow all applicable local fire, life-safety, and building codes governing door alarm devices on egress paths.
