Jablotron JS-22 Owner Manual

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.

 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.

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

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.

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)
