Perform the following steps to mount the detector:
1.
Open the detector by releasing (using thin screwdriver) the latch in the lower part of the enclosure (Fig.1).
2. Remove the PCB from the base by releasing the locking clip (Fig.2).
3.
Make holes (for mounting the sensor on the wall) in the embossings at the rear or side of the housing. The
detector can also be mounted on the SN-1 rotating holder (not included).
4. Lead the cables through the hole located in the upper part of the enclosure (Fig. 2).
5. Connect the wires to the screw terminals and configure the detector
(Information on the distribution of terminals and control elements with a description of the available functions
can be found in the following pages).
6. Close the lid of the sensor.
CAUTION! When closing the cover of the detector, check whether the spring of the micro switch tamper is
correctly pressed into the tapered socket in the lid.
7. Connect the supply voltage and wait until the LED of the sensor stops flashing.
CAUTION! Leave the field of view of the detector.
The arrangement of the elements of the detector on the PCB is shown in the figure 3a and 3b.

3. The detector configuration elements
The detector configuration uses the following elements mounted on the PCB:
Potentiometer
Five-position ON/OFF potentiometer
1.
Potentiometer - adjusting the microwave range (MW
)
To adjust the microwave range of the detector, use a potentiometer located on the PCB (Fig. 3a). The "+"
increases the range, and the "-" reduces the range of the detector.
The adjustment should be carried out in several steps. After the initial adjustment and closing the cover, check the area
of the sensor operation. Re-open the sensor housing and re-adjust the microwave range. Operating range of the MW
detector is adjusted with the DIP1 switch.
Caution! Detection sensitivity of microwave path should be adjusted to the size of the protected space.
Microwaves can penetrate gypsum walls, doors, etc., which may generate false alarms.
