8. Limitations of CO Alarms
(1) The CO Alarm will not work without good batteries. If the batteries have
been drained the Alarm will not give protection. Button test the Alarm weekly
and on return from holidays and other long absences.
(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 in the vicinity of the CO Alarm. Doors, air draughts and
obstructions can prevent the CO reaching the Alarm. For these reasons we
recommend CO Alarms are fitted both near and in bedrooms, particularly
if bedroom doors are closed at night. Additionally 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 behind a closed door or if it is too far away. RF interconnecting CO
Alarms greatly improves the probability that they will be heard. The Alarm may
not wake up somebody who has taken alcohol or drugs. The alarm sound may
be masked by other 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 6 years of operation.
