Please note that the time only begins to run once
the melody has been played through fully.
Sensitivity of the Motion Detector
With the sliding switch (7), the sensitivity of the
sensor can be adjusted in 3 steps.
H = high sensitivity
M = normal sensitivity
L = low sensitivity
Infrared Sensor Limiter
In order to target the chosen area effectively,
place one of the provided limiters on the sensor.
The operating range of the sensor is 5m for
360°, without a limiter. It has an open range
of ca. 140°.
INSTALLING THE RECEIVER
Unscrew the battery compartment cover and take
off the lid. Place 4x 1.5 V AA batteries inside, in
accordance with correct polarity, or attach mains
plug. Batteries are not required when using
mains supply and should be taken out of the
device, in order to prevent them running down.
Switching ON/OFF
There is a slide switch (1) on the side, with
which the device can be switched ON or OFF.
Slide the switch to the ‘ON’ position in order to
switch the device on.
press of the knob yields a new melody. The last
selection will automatically be stored.
“Alarm“ Function
Set the tone control knob (4) to the Alarm
position. If movement is subsequently detected
in the monitored area, the alarm will sound
immediately for approximately 3 - 4 secs.
However, any further movement in the area will
once again immediately trigger the alarm.
No Melody or Alarm at the Transmitter
Move the tone control knob (4) to the position
tone off. The transmitter will not produce any
sound should movement be detected in the
monitored area, instead it will only send a signal
to the receiver.
Delays in motion detection
A delay can be set using the slide switch (5).
This means that the motion detector will only
report new movement after another recognised
movement once the set time has passed. This is
useful, for example, if the motion detector is to
be used in areas with a lot of movement.
In position 1 the motion detector recognises a
new movement approx. 1 second after the last
recognised movement.
In position 10 the motion detector recognises a
new movement approx. 10 seconds after the last
recognised movement.
In position 20 the motion detector recognises a
new movement approx. 20 seconds after the last
recognised movement.
