The alarm must not be used outdoors!
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 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 lifting it off
carefully 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 gas 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 gas 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 (e.g. AS 05, Art.Nr. 33 133) or warning
light (e.g. 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
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 gas 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.
