First check that the green LED power indicator is flashing.
Then, to test the Alarm press and hold the test button for at least 5 seconds. This tests
the sensor, battery, electronics and horn. The horn will stop sounding when the button is
released. The Alarm will respond with one of the following status conditions:
1. The Green LED will flash and the horn will sound to indicate the Alarm is operating
correctly.
2. If there is a fault condition the yellow LED will flash and the horn will beep (see “Fault
Mode” in Table D).
3. If the memory has been set the Red LED will flash and the horn will give a full alarm
sound (see “Alarm Memory” section).
ATTENTION: Do not test with CO gas
We do not recommend testing the alarm with carbon monoxide as the results can be
misleading unless special apparatus is used.
However, if testing the Alarm with CO gas is required, the red LED flashing indicates the
presence of CO gas as per table B.
3.3 Cleaning your Alarm
Clean the outside case by occasionally wiping with a clean damp cloth. Do not use any
cleaning agents, bleaches, detergents or polishes, including those in aerosol cans. Avoid
spraying air fresheners, hair spray, paint or other aerosols near the CO Alarm. Do not place
air fresheners near the CO Alarm.
