Your Alarm
sounds for no
apparent reason
• Follow the detailed instructions in “What to do when the alarm
sounds“ section.
• If there are still problems:
- Ensure there are no fuel burning appliances in the vicinity which
could be leaking CO gas (e.g. even from next door).
- Ensure there are no fumes or aerosols in the area (e.g. paint,
thinners, hair spray, chemical cleaners, aerosol sprays, damp
proofing done with an aqueous emulsion such as Aminofunctional
siloxane and Alkylalkoxysilane).
- Ensure there is no outdoor source of CO in the vicinity (e.g. a car
with engine running, heavy traffic, heavy air pollution, barbecue
fumes etc).
- Ensure there is no source of hydrogen such as batteries being
charged (e.g. on boats or in Uninterruptable Power Supplies (UPS)).
- Ensure there is not excessive smoke or fumes from devices such as
Egyptian shisha, hookah or hubbly bubbly pipes, especially those
that use coal or charcoal to heat the tobacco.
- Press the test/hush button to silence the Alarm.
If the CO Alarm continues to sound it is possibly defective and
should be replaced - see “GETTING THE ALARM SERVICED” section
Test/Hush button
does not silence
the alarm
• If there are a number of Alarms interconnected and they are all
sounding, pressing the Test/Hush button on the unit sensing CO
(i.e. the one with the red light flashing) will silence the system.
Pressing any other Test/hush button will not silence the alarm.
• The Test/Hush button will only silence the alarm once during a CO
incident and only if the level of CO detected is less than 150ppm.
