Detex EAX500MC65 Surface Mount Battery Alarm with Mortise Cylinder Gray Finish

The EAX-500MC65 is a surface-mounted battery door alarm that monitors unauthorized use of emergency exits and restricted access doors. Detex designed this self-contained unit for installations where hard-wired alarm systems are not practical or cost-effective. The 100dB piezo alarm sounds when someone attempts an unauthorized exit, providing immediate notification to facility staff and deterring improper door use.

The alarm uses an intelligent circuit that automatically senses external magnet location and sets proper door handing during installation. The tapered cover design allows mounting on narrow stile doors where space is limited. A control key is required to silence the alarm once activated, preventing unauthorized reset. The tamper-resistant housing protects internal components from interference.

This door alarm supports NFPA 101 egress monitoring requirements for facilities that need to track exit usage while maintaining life safety compliance. Installation flexibility makes it suitable for IBC Chapter 10 means of egress doors where traditional wired alarm systems would be impractical.
