5) If the detector is OK, all three LEDs will flash briefly in sequence
and all symbols on the display (Ei208DW) will light up.
6) In order to make the detector resistant to unauthorized removal
and tampering, break off the small pillar on the base as shown in
Fig. 4a. To remove the detector from the ceiling it is now
necessary to use a small screwdriver which has to be inserted
between the detector body and the catch in the base (fig. 4b). The
locked detector can further be secured against rotating with a self-
tapping screw as shown in Fig. 4c

Alarm signalling
Pre-alarm: when the detector detects over 43 ppm CO, the red
ALARM indicator flashes in accordance with the table. This is usually
not a concern in a shorter time interval, unless the acoustic signal
sounds. Such a slightly increased concentration may come from
various sources, e.g. from cooking, barbecuing or starting a
combustion engine. The display shows the current carbon monoxide
level if it exceeds 10 ppm.
When the detector detects a potentially dangerous carbon monoxide
concentration, the red ALARM LED starts flashing. If the concentration
remains unchanged, the detector sounds the alarm with a built-in siren.
The table below shows the detector signalling depending on the
concentration and exposure time. The detector reacts sooner with
greater concentrations. The siren can be silenced for 4 minutes by
holding down the test button. If the dangerous concentration persists,
the siren is reactivated. The siren cannot be silenced when the
concentration exceeds 150 ppm.

1) Open the doors and windows to ventilate the area
2) Turn off all fuel appliances where possible and stop using them
3) Leave the threatened area as soon as possible
4) Get medical help immediately for anyone showing the symptoms
of carbon monoxide poisoning (headache, nausea)
Do not re-enter the property until the Alarm has stopped signalling

harmful concentration of carbon monoxide. If the Alarm has been
silenced by pressing the test button, wait at least 5 minutes so the
Alarm can check if the CO gas has cleared.
6) Do not use the fuel appliances again until they have been checked
by an expert.
Note: If the carbon monoxide concentration has been decreased
only by ventilation, this might only be a temporary solution. It is
necessary to find the carbon monoxide source.
Detector testing, maintenance, fault indication
The detector regularly checks its function to ensure problem-free
functioning. Any fault is immediately signalled with LEDs or with a
symbol on the display.
It is further recommended to test the detector using a test button in
the following cases:
1) After the system is installed.
2) Regularly once per week
3)
After prolonged absence from the building
4) After repair or servicing of any of the fossil fuel-burning appliances
Fig. 4c
5) Once per year using a CO gas testing kit
The following table displays the status signalling after pressing the
test button:

End of
life
When a low battery, detector failure or end of life is signalled,
the detector has to be replaced.
The carbon monoxide detector has a limited usable life which
runs out even if the detector is not used. There is a label on every
detector showing its usable life. The detector has to be replaced
after this date even if it does not signal any faults.
The detector requires no special maintenance. Keep it clean by
wiping it with a wet cloth from time to time. Do not use any aggressive
or abrasive cleaning agents.
