Troubleshooting - Ei Electronics Ei261ENRC Manual

CO Alarm Memory : A unit will indicate if it has been
in alarm previously by flashing the red light for 2
seconds every 40 seconds (2 flashes for 50 ppm CO,
4 flashes for 100 ppm CO and 8 flashes, for 300 ppm
CO). When the Test/Hush button is pressed, the red
light flashes (as per Table B on page 4) to indicate
the previous CO alarm level detected. The memory
is cleared by holding down the Test/Hush button until
the red light stops flashing.

14. TROUBLESHOOTING

1. ALARM DOES NOT WORK WHEN THE TEST
BUTTON IS PRESSED:
- Check that the green mains power light is on. If it is
off check the wiring, fuse, circuit breakers etc.
- Hold the Test/Hush 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
defective.
- Press the Test/Hush button for approximately 20
seconds to reset the unit. If the beeping and the
amber light flashing re-occurs replace the CO
Alarm.
3. ALARM BEEPS EVERY 40 SECONDS (without
amber light flashing):
- Rechargeable cells depleted. Reconnect mains
power if green light is off.
4. ALARM SOUNDS FOR NO APPARENT REASON:
Follow the detailed instructions in Section 1 on
page 4 entitled "WHAT TO DO WHEN THE ALARM
SOUNDS". If there are still problems:
- Ensure there are no fuel-burning appliances in
the vicinity which could be leaking CO gas (e.g.
even from next door).
- Ensure there are no fumes in the area (e.g. paint,
thinners, alcohol, hair spray, chemical cleaners
aerosol sprays etc).
- Ensure there is no outdoor source of CO in the
vicinity (e.g. a car with engine running, heavy
traffic, heavy air pollution, barbecue fumes etc).
- Press the Test/Hush button to silence the alarm.
If the unit continues to sound it is possibly defective
and should be replaced. Follow the instructions in
"GETTING YOUR CO ALARM SERVICED".
