(2) Carbon Monoxide must enter the unit for it to be detected. There may be Carbon
Monoxide in other areas of the house (e.g. downstairs, in a closed room etc). but not

CO reaching the Alarm. For these reasons we recommend. CO Alarms are fitted both

install in rooms where members of the household spend much of their time, and in
rooms with potential sources of CO gas.
(3) The CO Alarm may not be heard. The sound output is loud but it may not be heard

sounds such as T.V., stereo, traffic noise etc. Fitting CO Alarms on either side of closed
doors will improve their chance of being heard. This CO Alarm is not designed for
people with impaired hearing.
(4) CO Alarms don’t last indefinitely. CO Alarms are sophisticated electronic devices
with many parts. Although the alarm and its component parts have undergone
stringent tests, and are designed to be very reliable, it is possible that parts can fail.
Therefore, you should test your CO Alarm weekly. The CO Alarm must be replaced
after 5 years operation.
