The CRL DETEX® EAX500 Battery Powered Surface Mount Exit Alarm is designed for applications requiring an alarmed exit device on secured doors. The alarm, with approximately 100db, will sound when an unauthorized exit occurs.


The redesigned shape and smaller size of the EAX500 make it the ideal choice for quick and easy installations on emergency exit and restricted doors. Alarm can only be silenced by proper control key. The standard extended bypass feature allows alarm to remain bypassed when door is open, and to automatically re-arm upon door closing. The EAX500 intelligent circuit senses the external magnet location automatically and sets the correct door handing. The patented plastic template allows for foolproof alignment of internal magnetic door contact and accurate installation.

NOTE: Does not come with bottom cylinder lock.
