Tech Tip     


The EAX-2500 does not have a cover lock, but rather uses a tamper switch to guard against tampering.  To replace the battery or service the EAX-2500, the alarm must be disarmed with the key, prior to removing the cover.  If anyone attempts to remove the cover while the alarm is armed, the unit will sound alerting those nearby that someone is tampering with the alarm.


The cover screws are 2 1/8" long and are required to hold the tamper plunger lever to the rear. If you have the faceplate removed while servicing the alarm, you must push the tamper plunger lever to the rear away from the faceplate before arming the EAX-2500 or the alarm will sound. One of the most common troubleshooting calls regarding the EAX-2500 is the report of false alarms and the most typical resolution to this problem is the tamper plunger lever not being held in the correct position.


Only hand tighten the cover screws. If you use a power driver and over torque the cover screws, you may warp the faceplate and adversely affect operation.
