Electrical connection
230 V model:
The CO alarm is delivered with a connection cable and Euro plug. This
is to be used with a 230 V AC (alternating current) power socket.
12 V model:
Electrical connection to 12 Volt direct current (DC) only.
Tolerance: -15% / +20%
We recommend a connection cable with core identification.
Connect the supply cable to the '+' and '-' connection terminals.
Make sure that the voltage is disconnected when connecting the
current supply.
Make sure the connections have the correct polarity!
Switching outputs
The CO alarm has two switching outputs which are used to control an
alarm system or other signal transmitters and devices. The respective
connection terminals are under the cover plate.
Only connect the alarm when the power supply is disconnected!
12 Volt switching output
Switched 12 V DC signal for the direct control of an external horn (AS
05, Art.Nr. 33 133) or warning light (BL 01, Art.Nr. 33 134), for
example. The maximum load is 200 mA. The connection is made via a
2-pole +/- terminal output connection.
Make sure the connections have the correct polarity!
Relay output
Potential-free NO and NC contact. These contacts are used for
connection to an alarm system, a telephone dialer, a warning light or
similar. Connection to an NO contact (normally open
event of an alarm) is made at the N.O. and COM terminals.
Connection to an NC contact (normally closed
an alarm) is made at the N.C. and COM terminals.
When the CO alarm is not powered and in normal mode, the N.C. and
COM contacts are closed, i.e. the relay is at rest.
When using the relay output with voltages higher than 25 Volt AC or
25 V olt DC, a terminal box on site must be used for connection of the
cable to the external consumer (e.g. warning light). Installation must
be carried out by a qualified electrician.
Commissioning
As soon as the CO alarm has been properly connected to the current
supply, an automatic self-test is conducted: The green POWER LED
flashes for up to 90 seconds. The green, yellow and red LEDs then flash
alternately. Three dashes will appear on the display. This takes
approx. 50 seconds. A signal horn sounds when the self-test has been
successfully completed. The green POWER LED then indicates that the
alarm is operational.

Exception:
The green POWER LED will flash for 90 seconds if, during
commissioning, there is already a CO concentration sufficient to
trigger an alarm. The system then switches into operating mode and
the prevailing CO concentration shows on the display for 15 seconds.
Depending on the CO concentration, the alarm signal triggers with the
time delay specified in the chapter entitled 'Technical specifications'.
Operating functions
Normal mode
The green POWER indicator lights continuously. The CO alarm is
operational.
Alarm
The device emits an alarm if the sensor registers a carbon monoxide
concentration in excess of the sensitivity threshold set in the factory: A
repeating sequence of 4 signal tones with simultaneous illumination
of the ALARM light is output.
Repeating sequence of 4 signal tones, simultaneous red ALARM light
A signal is passed/given to any other connected devices.
The alarm continues until the carbon monoxide concentration falls
below the preset sensitivity threshold.
Do not disconnect the CO alarm in the event of an alarm!
Mute function
If necessary, the acoustic alarm during the alarm status can be turned
off for 5 minutes by pressing the TEST button. The red ALARM light will
continue to flash.
The acoustic alarm will sound again if carbon monoxide is still present
after the 5-minute mute phase.
If there is uncertainty about the cause of the alarm, assume that there
is a dangerous concentration of carbon monoxide. In that case,
evacuate the building.
Note:
!
The mute function cannot be activated if the carbon monoxide
concentration exceeds 350 ppm.
!
The mute function can only be used once during an ALARM phase,
i.e. the acoustic alarm can only be suppressed once for a period of
5 minutes.
Returning to normal mode
The alarm ends if the carbon monoxide concentration falls below the
preset sensitivity threshold. The green POWER indicator lights
continuously.
Fault display
The CO alarm carries out a continuous self-test. Flashing of the yellow
FAULT indictor indicates the presence of a fault. In addition, the letter
"F" appears on the display, and two short signal tones are issued per
minute.
