(The batteries will usually last over 4 years in standby under normal conditions. An undepleted battery can power a unit in alarm for over 100 hours. The life will be reduced if the unit regularly goes into alarm or if it is exposed to excessive temperatures for long periods).

Amber Fault Indicator

If the unit beeps and the amber light flashes simultaneously every 45 seconds the self-checking circuitry may have detected a fault. Follow the checklist to see if the unit is actually defective.

Checklist in the event of problems

Check the ‘pull’ tag has been removed to connect the batteries.

Check there are three batteries installed with the correct orientation in the battery compartment. (If the batteries are accessible remove one battery for 1 minute to reset the microcontroller in the unit).

If the problem persists replace the batteries if they are accessible.

If none of the above solve the problem the unit is probably defective and must be replaced. See “Getting the CO Alarm Serviced Page 28)”.

Testing with Carbon Monoxide

The unit can be tested with CO by using one of the kits that comes with CO either in a glass phial or aerosol can. Follow the instructions on the kit. It is best if possible to inject the CO gas into the gas entry holes, see Figure 5a. When it senses the CO, it flashes the red light (as per Table B) to confirm that is detecting CO gas.
