Function checks

Test the alarm once a month to ensure it is functioning
correctly.
To do this, keep the TEST button pressed for 4 seconds.
This activates the function test. The three LED light
Open all doors and windows to increase ventilation
and allow the carbon monoxide to escape.
Stop using all combustion devices and, if possible,
make sure they are switched off.
If the alarm continues, clear the building. Leave
doors and windows open.
Do not enter the building again until the alarm
signal has muted.
Get medical assistance for anyone who shows
symptoms of carbon monoxide poisoning. Draw
attention to the fact that carbon monoxide
poisoning is suspected.
Call the maintenance or service company for the
equipment or your gas or fuel supplier. Explain the
problem.
Do not use the combustion equipment again until a
person with the required qualification has inspected
the equipment in accordance with applicable
requirements and has approved the equipment for
use.
The CO alarm issues an output signal which can be
used to trigger auxiliary equipment such as a
ventilation fan or a gas shutoff valve. Once it has
been triggered, it may be necessary to manually
reset the equipment. The equipment should not be
reset until the source of the carbon monoxide has
been identified and the fault has been corrected. In
the case of gas-operated devices, if the gas supply
was cut off by closing the solenoid valve, it may only
be opened by a qualified plumbing contractor or a
specialist from the gas supplier.
