The keyboard KP1W is intended for indoors installation on dry and smooth surface.
Usually it is located on the wall, by the front doors, 120-140 cm above the ground.

Open the keypad case – insert a flat-head screwdriver in the hole in the bottom part
of the case and press the latch. Then, press the other latch and carefully draw aside
both parts of the case, starting from the bottom one.
2.
Mark and drill holes in the wall for assembly of the back part of the case.
3.
Screw down the back part of the case.

Put in a CR123A battery as per markings on the plate. The incorrect placement of the
battery will result in the failure to start the device. As soon as the battery is inside,
two LEDs (for battery – red one, for transmission – blue one) and keys backlight will
light up temporarily.

Door opening sensor
The keyboard KP1W is equipped with a feature enabling connection of opening sensor
(reed relay), which can be used as a door opening sensor.
The NC connector (normally closed) used in this case should be shorted, if the possibility
to connect the sensor is not used. The connector can be found on the keypad board and
labelled 9 in Figure 7.
This sensor in the alarm system CPX220NWB will have assigned the same line number as
the keypad.

CONTROL PANEL LOCATION
The control panel should be located in the central part of the object. The central location
of the panel usually provides good communication with all wireless detectors. See
drawings 8 and 10.
