All exit alarms quit working, roof and window exits. The alarm stays on continous. The back exit and side exit work properly, has own wiring. Any suggestions, recommends. Ground circuits checked out to switches.??
Check roof hatches first push up on rear of hatch mounting where the lock plate meets the hatch lid. next open the hatch and depress the micro switch in the body side of the connection and see if that shuts off the buzzer also check for wires unhooked from the switch. If no joy check window switches use a small screwdriver to push in the pin and let it snap back to work the window switch. push down on window latches to see if that works the detents in the handle are the weak points.
