Mount-on contact (A-2922-0)
For connecting to doors and win-
dows. The mount-on contact con-
sists of a permanent magnet and a
reed contact. The contact is open
when the magnet is in contact. An
alarm signal is signalled if the
magnet is separated from the
contact. Use the signal cable to
connect the mount-on contact to the
Radio Alarm Transmitter (alarm
accessories socket).
Smoke detector (A-2926-0)
The smoke detector is triggered by
smoke from smouldering fires and
signals an alarm. Attach it to the
ceiling of the room to be monitored
and use the signal cable to connect
the smoke detector to the Radio
Alarm Transmitter (alarm accesso-
ries socket).
Call button
Pressing the call button on the
Alarm Transmitter causes a signal to
be triggered on every receiver which
is set to the same radio channel as
the transmitter. The call button lamp
lights up to indicate this. This makes
it possible to call people who are in
different rooms. Also, this button
can be used for checking the system
is functioning even when the tele-
phone cable is not connected.

Mains operation

You can also operate your Radio
Alarm Transmitter via the plug-in
power supply unit. To connect the
PSU, insert the connector on the end
of the PSU cable into the correspon-
ding socket on the left-hand side of
the device. Then plug the power sup-
ply unit into the normal 230 V socket
in your house.
Radio range
Note the following points when
using the Radio Alarm Transmitter:
The radio signals are designed to
have a range of 80 meters under
optimum conditions.
The following conditions may result
in a reduced range:
- Signal transmission through buil
ding structures or vegetation
- Interference from TVs, computer
monitors and mobile phones.
Under certain circumstances, this
Radio may prevent the receiver from
functioning at all.
- Positioning of the transmitter at an
unfavourable distance from surfa-
ces which reflect radio waves, for
example floors and walls.
This may lead to the signal wave
being weakened or even cancelled
out by the reflected wave.
- Metallic objects reduce the range
due to the shielding effect of the
metal.
- Particularly in towns and cities,
there may be many other sources
