2 short signal tones every 60 seconds, yellow FAULT indicator flashes,
"F" appears on the display
The FAULT indicator indicates a possible failure. Reset the indicator by
disconnecting the power supply for 3 minutes. If the fault indicator is
still active, there is contamination in the device or the CO alarm has
reached the end of it's service life of approx. 6 years. The CO alarm
must be replaced!
Digital display
The carbon monoxide alarm is equipped with a digital display (LCD
display) to show the CO concentration. The unit shown on the display
is parts per million (ppm). The LCD display can show values between
30 and 999 ppm.
Normal mode
No values are shown if the ambient air is normal.
Activation of the LCD by the customer
Press the TEST button for 1-2 seconds to activate the LCD:
!
The following display appears if the measured CO concentration is
less than 30 ppm:
- - -
!
The measured CO value is displayed if the concentration is greater
than 30 ppm.
The display remains active for 15 seconds.
Automatic activation of the LCD
If the CO concentration rises to a value of more than 50 ppm and the
carbon monoxide alarm goes into ALARM status, the digital display
will
automatically
activate.
The display remains active for as long as the alarm continues.
What to do in the event of an alarm
Remain calm in the event of an alarm. Carry out the following
measures:
!
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.
!
Make sure all residents are warned.
!
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
22 -
GB
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
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 indicators are activated
alternately during the function test. Three dashes 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 once a
month!
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.
Maintenance and cleaning
!
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).
