5.5.6.7 RWT 72 (Contact sensor / Remote lock)
The wireless contact transmitter can be operating on one hand directly as the status detector of
the magnet, or on the other hand it is possible to connect external wired contacts to the
transmitter. A combination of the two is also possible.
Assembly instruction

Open the detector (Fig. 1) and remove the 3V-lithium battery from the plastic bag and insert
it (Fig. 2), paying attention to the correct polarity

Remove the circuit board carefully with a flat screwdriver (Fig. 3).

Remove the base plate by pushing in/down the interlock on the left corner and removing the
base plate. Tighten the base plate with the provided screw (Fig. 4).

Slide the casing back under the base plate and put the circuit board back in.

Set DIP-switches according to you needs (* = Default value)
DIP Function
1-3 No used
4 Internal reed contact (Magnet contact)
ON: Disabled OFF*: Enabled
5 Determinate external contact
ON: Normally Closed (NC) OFF*: Normally Open (NO)
6 Response time for external contact
ON: Slow (500ms for operation with external magnets)
OFF*: Fast (10 ms for operation with shock sensors)
7 Determinate HOLD-Status of transmitter
ON: There will be a 2.5 min dead time between two transmission (Restore will be send
immediately) => battery saving modus
OFF*: Every change of state will be transmitted
8 Determinate Transmit power
ON: RF low power (If transmitter is close to receiver)
OFF*: RF high power
Use internal reed contact:

Open the magnet and tighten it with provided screws parallel to the transmitter. The magnet
must be in line with the lower end of the housing, next to the DIP-switches!

The function led should illuminate on opening and closing of the window/door.

The gap between magnet and transmitter must be below 35mm if window/door is closed.
Use with external contact:

In addition or alternate to the internal reed contact you can use an external contact
connected to screw terminal (i.e. external magnet, glass-breaking and vibration detectors).

The cullet detector/glass breakage detector has a sensitivity radius of 2m. It should be
mounted onto the inside of the window with a distant of at least 2 cm to the window frame.

The vibration detector should be mounted onto the window frame.
