12. TROUBLESHOOTING
1. ALARM DOES NOT WORK WITH THE TEST BUTTON:
(1) Check that the green mains power light is on. If it is off check the wiring, fuse, circuit breakers etc.
(2) Hold the test button down for at least 5 seconds.
2. ALARM BEEPS AND AMBER LIGHT FLASHES EVERY 40 SECONDS:
If the alarm beeps and the amber fault light flashes every 40 seconds, the CO sensor is probably defec-
tive. Press the test/hush button to reset the unit. If the beeping and the amber light flashing re-occurs
replace sensor module.
3. ALARM BEEPS EVERY 40 SECONDS
(without amber light flashing)
Rechargeable cells depleted. Re-connect mains if green light is off.
4. ALARM SOUNDS FOR NO APPARENT REASON:
Follow the detailed instructions on the top of page 2. entitled “What to do when the alarm sounds”. If
there are still problems:
(1) Ensure there are no fuel-burning appliances in the
vicinity which could be leaking CO gas (e.g. even from next door).
