Warning: The Transmitter is only
designed to work with low vol-
tage doorbells. Do not connect
the thin doorbell cable to the
mains supply. This could be
extremely dangerous for the user
and may destroy the transmitter.
Cable for doorbell connection
A-2950-0 ( 5 m)
A-2951-0 (10 m)
The doorbell voltage must be at
least 3 Volts and must not exceed
15 Volts. Both AC and DC can be
used.
Pressing your respective doorbell
will now cause each receiver to
flash with the corresponding number
of flashes. The receiver will flash
differently for doorbell 1 and door-
bell 2.
Note: For the connection of 2 door-
bells, two cables are necessary.
Failure causes
- If your doorbell system uses direct
current voltage, you have not con-
nected the wires with the correct
polarity. Swap over the wires.
- The doorbell voltage of your
system is too low. Either contact
an electrician to have the door-
bell system converted or use the
doorbell transmitter - acoustic.
Doorbell connection - acoustic
Plug the doorbell microphone lead
into the respective socket at the
universal-lisa.
Lay the cable to the
door chime and attach the micropho-
ne to the door chime by peeling off
the paper circle to reveal the sticky
ring beneath. For optimal operation
of the transmitter the sensitivity
may be adjusted so that only the
doorbell activates the transmitter
and not background noise.
Setting the sensitivity
1. Set the sensitivity controller to its
lowest level (turn to the anti-
clockwise to stop).
2. Activate the doorbell and gradu-
ally increase the sensitivity of the
transmitter (by turning the dial
clockwise) until the transmitter
reacts to the doorbell.
3. If your intercom system operates
with different signal tones, make
sure that both signal tones are
reliably detected.
