The Detex EAX-500W Weatherized Exit Alarm is designed for applications that require a battery-powered alarm on secured doors, particularly emergency exits that open to the outdoors or wet environment. The alarm, with approximately 100dB, will sound when an unauthorized exit occurs. The redesigned shape and smaller size of the EAX-500W makes it the choice for quick and easy installations on emergency exit and restricted doors and gates.
