JS-22 dual-zone PIR motion detector 2 MKZ51101
The JS-22 dual-zone PIR motion detector
The detector is intended to detect human body movement in buildings.
Using two sensors ensures better immunity against triggering by moving
pets.
The signal is processed by a multiple signal analysis method which
guarantees excellent sensitivity and a high resistance to false alarms.
Detection analysis can be adjusted to increase its immunity (if installed in a
problematic location). The detector distinguishes itself with excellent
immunity against high frequency interference and other false signals. It can
be installed on a flat wall or in a corner.
Installation
Installation should only be undertaken by technicians holding a
certificate issued by an authorized distributor. The detector can be installed
on a flat wall or in the corner of a room. The expected installation height is
120 cm above the floor. Objects rapidly changing temperature, (electrical
heaters, gas appliances etc) should not be positioned within the detection
field. Moving objects with a temperature close to that of a human body
(such as curtains moving above a radiator) should also be avoided. The
detector should not face windows or spotlights or be installed in places with
obvious air flow (e.g. near ventilation fans, air holes or badly sealed doors
etc.).
There should be no obstacles blocking the detection field and the
detector should be kept away from metal objects (they could interfere with
radio communication).
1. Open the detector cover (by pressing the tab) – do not touch the
PIR sensors inside
2. Remove the PCB – it is held by two internal tabs
3. Make the necessary holes for cables in the rear plastic cover and
punch screw holes (at least one screw should go through the
tamper-sensitive section)
4. Screw the rear cover to the wall approximately 120 cm above the
floor (vertically, with the tab down)
5. Return the PCB into the rear housing and connect the cable wires
to the terminals
6. Close the cover
Warning: avoid dirtying or damaging the PIR sensor inside the detector
(by touching, greasing or scratching).
DIP switches
Switch 1: LED ON / OFF in the LED ON position, each movement is
signalled by the flash of a red LED, an alarm is signalled by a 2-second flash.
The signalling is blocked in the OFF position.
Switch 2: NORM / HIGH defines the immunity to false alarms.
The NORM position combines very good immunity with fast sensor
reactions. The detector is activated if it detects movement in one zone and then
in the second zone within 3 seconds.
The HIGH position increases sensor immunity at the expense of speed (it is
used with problematic installations). The detector is activated if there are two
NORM activations in 10 seconds.
Warning: The most frequent cause of false alarms is wrong detector
positioning.
Terminals
+12V, GND power supply
PIR, PIR PIR alarm output – normally closed
TMP, TMP TAMPER output – normally closed
Detector testing
After switching on the power, wait for 1 minute for the detector to
stabilize. If LED ON is activated, stabilization is signalled by a
continuously lit red LED.
Each detected movement is indicated by the detector’s LED (LED
switch in the detector must be in LED ON position during testing)
Move in the covered area to test the detector coverage.
Opening the detector cover causes the TMP terminals to open-circuit
Detection characteristics
The detector has two detection zones each of which covers an angle of
120° and a distance of 12m. The imaginary dividing line between both
zones is determined by the detector installation height. The recommended
installation height is about 120cm.
