Resolution Steps
Make sure the smoke detector heads are properly mounted and seated. Verify that smoke detector power is present, particularly for separately powered 4-wire devices. Check all system wiring to verify that each circuit is free of grounds and extraneous voltages. Use a multimeter to check each circuit for extraneous voltage and resistance measurements. Restore or replace the defective device (switch, wire, notification appliance, etc.) in accordance with the device’s instructions.
