Installation
Make sure that the voltage is disconnected during installation and when
connecting the power supply!
Two screws are used to fasten the alarm to the wall or selected location. Use the
enclosed spax screws. Both the assembly holes and the connection terminals are under
a cover plate. The cover plate is attached simply with two pins and can be lifted off by
moving it sideways without the need for tools.
Make absolutely sure to install the alarm at the height specified in the
chapter entitled 'Placement'!
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
12 Volt switching output
Switched 12 V DC signal for the direct control of an external horn or warning light, 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 closes in the event of an alarm)
is made at the N.O. and COM terminals.
Connection to an NC contact (normally closed opens in the event of an alarm)
is made at the N.C. and COM terminals.
When the CO alarm is de-energised and in normal mode, the N.C. and COM contacts
are closed, i.e. the relay is at rest.
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!
