b. PCB layout
1. Pyro-sensor (do not touch this sensor!)
2. Walk test & alarm indicator
3. Tamper switch
4. Pulse count jumper ("harsh": for environment with high risk of false detection)
5. LED on/off jumper (on = flashing during start-up, on during operation)
6. Connection terminal block:
Tamper: if a tamper switch is required, connect these terminals to a 24h
normally closed (NC) zone in the alarm control panel. Opening the
housing will trigger a tamper signal.
12Vdc: connect (+) to an 8-16V power source, usually from the alarm control
panel. Connect (-) to the common grounding point.
Alarm: the alarm output relay of the detector. Connect these terminals to a
normally closed (NC) zone in the alarm control panel.
c. Installation
• Install the detector indoors, on a stable surface with a clear view on the protection area.
• Avoid mounting where hot or cold air may blow directly onto the device and where objects
in the detection field may change temperature rapidly (heating or air-conditioning devices).
• Considering the detection angle of the device (see figure on the right), corner mounting is
recommended, at a height of 2 to 3 meters.
Procedure:
1. Open the cover by inserting a small screw driver into the edge of the unit and turning it to release the cover.
2. Remove the PCB by releasing the two fixing screws from the support post - DO NOT DROP THE PCB!
3. Numerous "knockouts" are provided on the back plate. Punch the one which will provide the best cable entry.
4. The two fixing holes on the back of the back plate are for surface mounting. The two fixing holes on the left and
right of the back plate are for corner mounting. Fix the back plate firmly on the wall with the two enclosed screws.
5. Put the PCB back onto the back plate and fix it firmly. Connect the wires to the terminal block.
6. Clip the front cover back in place on the back plate. See to it that the tamper switch is depressed when the front
cover is in place.
