Detex EAX-500SK4 Black Exit Alarm Surface Mount Battery

Product Description

The DETEX EAX-500SK4 BLACK is a surface-mount exit alarm designed to monitor door-open events and alert occupants with an audible signal when a protected exit is used. The unit runs on battery power, eliminating the need for hardwired electrical connections and simplifying installation in locations where conduit runs are impractical. It ships with two MS-1059S magnetic switches that detect door position and trigger the alarm when the contact gap exceeds the set threshold. This device is typically installed by security technicians, locksmiths, or general contractors working on access control and life-safety projects.

The EAX-500SK4 BLACK is suited for commercial and light-industrial applications where exit monitoring is required without a full hardwired access control system. Common installations include stairwell doors, warehouse exit doors, office suite egress points, and secondary building exits. The black finish allows the unit to blend with dark-colored door frames and hollow metal doors. Because no low-voltage wiring to a central panel is required, the alarm functions as a standalone deterrent and notification device.

Key Features

• Surface-mount form factor allows installation without cutting into the door or frame
• Battery-powered operation eliminates the need for hardwired electrical supply
• Includes two MS-1059S magnetic switches for reliable door-position sensing
• Black finish suits dark door frames and hollow metal door applications
• Standalone operation provides audible exit monitoring without a central panel

Compatibility

Designed as a standalone surface-mount exit alarm compatible with standard swinging door assemblies where magnetic switch mounting is feasible on the door and frame.

Installation Notes

Installation is typically performed by a licensed security technician or qualified contractor familiar with life-safety hardware. Mount the alarm body to the door frame and position each MS-1059S magnetic switch according to the manufacturer alignment guidelines to ensure consistent gap sensing. No electrical power shutdown is required for battery-powered units, but confirm battery polarity and charge before commissioning. Verify that the installation meets all applicable local building and fire codes, including IBC and NFPA 101 egress requirements, before placing the device in service.
