Mounting the detector
1.
Remove and retain the screw from the bottom of the PIR and lift off the cover.
2.
Carefully remove the electronic module from its retaining clips, ensuring
not to touch the pyroelectric sensor
(Illustration 1).
3.
Use mounting points “A”, if you are fitting the detector in a corner. Use mounting points “B”, if you are fitting the detector
on a flat surface. Use a small drill to create two fixing holes at the mounting points (Illustration 2).
4.
Hold the base of the PIR in the chosen position, ensuring that the front of the PIR will face
towards the center of the protected area, mark and drill two fixing holes in the wall.
Choose one of the cable entry holes “C” and make a third hole in the detector base. Put one end of the wire through this
hole “C”, then secure the PIR to the wall.
5.
Replace the electronic module into the retaining clips, ensuring that it is correctly positioned and firmly seated.
6.
If required, select the PIR LED “ON” or “OFF” option and the sensitivity (pulse count) by setting the corresponding
jumpers on the electronic module. Note that Pulse 1 option is more sensitive than the pulse 4 option. Pulse 1 option is used
when it is necessary to activate an alarm on the first detected pulse, or in high security installations – where fast “catch”
performance is of greatest importance. Pulse 2 or 4 settings provides improved protection against false alarms caused by all
types of environmental disturbances. (Illustration 3)

Connect the wires in accordance with the terminal block connections.
–
12V+
Connect to a regulated D.C. power source, observing correct polarity.
TAMP
Connect to a Tamper or 24 Hr. zone, NC in the control panel. Note these are normally closed switch contacts
which
open
when the tamper opens.
ZONE
Connect to an Alarm zone, NC in the control panel. Note these are normally closed relay contacts which
open
when the detector alarms.
