Setup as a baby alarm
The Acoustic Universal Transmitter can register a crying child and then transmit an
according signal to all assigned Lisa-Signolux-receivers within reach.
To do so, it is neccessary to aquire the baby-microphone cable (Item no. A-2691-0,
available as accessory). The included microphone cannot be used for this purpose!
Mount the baby microphone in the proximity of the child's bed. A self-adhesive velcro
band is supplied for this purpose.
For reasons of health and safety: Make absolutely sure that the child
cannot reach the microphone and /or the attached cable!
Plug the baby microphone cable into socket #2 of the underside of the Acoustic Uni-
versal Transmitter. For a reliable transmission, the sensitivity control should be set in
such a way that the transmitter reacts securely to the child's crying. Method:
- Set the sensitivity control #2 to the most sensitive (extreme right, turn clockwise).
- Should the transmitter react to neglegible noises (e.g. snoring, sighing, sniffles),
please decrease the sensitivity in small steps (turn counter-clockwise) until the
transmitter stops to react to irrelevant sounds.
The exact setting needs to be found by multiple changes to the sensitivity, in order
to match your specific requirements.
The baby alarm function can be conveniently switched on and off with the baby alarm
switch (Figure 1).
Please note:
Using the baby microphone requires a higher amount of energy from the trans-
mitter. This causes the batteries to suffer a shorter life span, the stand-by time
reduces down to approx. 100 days per battery change.
Therefore we emphasize on using the Lisa-Signolux power supply if the Acoustic
Universal Transmitter is used as a baby alarm.
Power supply connection:
The A-2690-W power supply unit, which is available as an accessory, can be connec-
ted to the 7.5 V DC connection socket. However, it is advisable to have operational
batteries in the device, as these serve as an emergency power supply in the event
of a power failure.
