The Detex EAX-2500 is designed for applications requiring a hardwired AC/DC alarm on secure doors (with optional 9V battery backup). The alarm, with approximately 100dB, will sound when someone attempts an unauthorized exit. The EAX-2500, with its smaller size and designed to fit in a standard 4″x4″ outlet box makes it the choice for quick and easy installations on emergency exit and restricted doors.


A mortise cylinder is used to arm / disarm the unit.  The cylinder is sold separately since many buildings have their own set of cylinders.  We provide the option above to order the cylinder with the unit.  Should you want to provide your own cylinder use a standard 1-1/4” mortise cylinder with a straight cam.



The standard method of mounting uses a 4 x 4 double gang electrical box.



Thin gauge wire (22 ga or so) is used to wire the alarm.  For single doors, one magnetic contact switch is used.  This is the standard contact type often found in home and business security systems.  Double doors use two contact switches, one for each door.

Whether wiring for a single door or double doors the wires are configured to form a compete loop, from the alarm to the switch(es) and then back to the alarm.

When the unit is powered on, closed doors allow the signal to flow through the loop.  Should a door open the loop is broken and the alarm sounds.

You may use any type of contact switch.  There are hundreds to choose from and most are inexpensive and readily available.

If you would like to order switches with this unit we’ve provided that option above.  The model we use is GE’s 1085W-M because it comes with it’s own wire leads for each connection.  The color is brown but it may also be painted.
