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.
Function checks
The carbon monoxide alarm should be checked once a week 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 indicators are activated alternately during the function test.
Three crossbars appear on the display. The signal horn sounds for 2 seconds at the
end of the function test.
If the carbon monoxide alarm is functioning properly, the green indicator lights up again
permanently.
The function test should be carried out regularly, at least weekly!
Exceptions:
A function test cannot be carried out during an alarm.
If there is a CO concentration sufficient to trigger an alarm - but an alarm has not
been triggered yet - the current CO concentration is displayed for 15 seconds when
the TEST button is pressed. In this case, a function test is not started.
False alarm
To fulfil its purpose, the carbon monoxide alarm is set so that it is very sensitive. The
system's sensor can therefore also respond to other gaseous media. The use of aerosols
(propellants in sprays, etc.) and high tobacco smoke concentrations can also trigger
an alarm. The device can also react to brief emissions of exhaust gas, for example,
when the equipment starts.
Regularly clean the housing of the carbon monoxide alarm with a duster or slightly
damp cloth. Remove as much of the dust deposits as possible from the slit openings
in the housing. Never use household cleaners with ammonia (spirits of ammonia) or
other chemicals, such as cleaning agents or solvents.
The CO alarm must never be sprayed with water!
The carbon monoxide alarm must not be painted or coated.
Regularly check the functionality of the device (see the chapter on function tests).
