The DETEX EAX-500SK1 GRAY is a surface-mount exit alarm designed to monitor emergency exit doors and alert occupants when a door is opened without authorization. The unit runs on battery power, eliminating the need for hardwired electrical connections during installation. It ships with one MS-1039S magnetic switch that detects door movement and triggers the audible alarm. This alarm is a common choice for facility managers, security contractors, and commercial door hardware installers working on code-compliant exit monitoring applications.
The EAX-500SK1 GRAY is suited for commercial and light industrial settings where exit door monitoring is required. It mounts directly to the door surface without cutting into the door or frame, making it appropriate for retrofit installations on existing exit doors in offices, warehouses, schools, and similar occupancies. The gray finish integrates cleanly with standard commercial door hardware in most environments.
Designed as an OEM-style surface-mount exit alarm for commercial door applications requiring battery-powered door monitoring with a magnetic switch sensor.
Installation is typically performed by a licensed door hardware contractor or security installer familiar with exit device requirements under applicable life safety codes. Mount the alarm body and magnetic switch to the door and frame per the manufacturer template, ensuring proper gap alignment between the switch and magnet. No electrical shutoff is required for battery-powered units, but verify battery installation polarity before closing the door. Confirm that the installation meets local fire and life safety code requirements before placing the door back in service.
