Detex The Detex EAX-500 exit door alarm is relied on in the retail, healthcare, educational, restaurant, and commercial industries for bringing attention to the unauthorized use of an emergency exit, or restricted door. By sounding an alarm of approximately 100dB, the Detex EAX-500 alerts a manager, as well as people nearby of a situation. It could be a shoplifter trying to make off with merchandise, or a simple misunderstanding. Either way, the Detex EAX500 door alarm helps facilities and businesses protect themselves, while ensuring they meet building codes.  A mortise cylinder is required for arming and disarming.  We offer the ilco brand mortise cylinder, model 7185SX1-28 at checkout if you will not be using your own.
