  If the Zone Alarm Indicator and Fire Alarm Indicator light up on your Horing Lih Control Panel, first isolate the problematic circuit. Then, use a multimeter to measure between the loop line and loop common line to check for a short circuit or to verify that the resistance value is normal (4.7k). After isolating the circuit, reset the control panel. Also, check the external wiring for any short circuits and inspect the detectors for defects.
