★ Connect the 2 wires to the PIR, polarity is not important.
★ Run the cable back to the Control Unit, fixing the cable with cable clips and enter the wire
into the back of the Control Unit through any convenient cable hole.
★ Connect to zone 3 or zone 4 terminals in the Control Unit as required, connection polarity is
not important. See Illustration 3 on page 8
★ In the Control Unit, against each of the two PIR connection terminals (zone 3 and zone 4),
there is a 3-position (0,1,2) slide switch. These switches are factory pre-set at position “0”
when no PIR is connected. When connecting one piece of PIR to the zone, you need to set the
corresponding switch to position “1”. When connecting 2 pieces of PIR to the same zone
terminals, put the corresponding switch to position “2”. The wiring to connect two pieces of
PIR to one same zone terminals are as Illustration 7.
When the two PIRs are running in the same direction:
When the two PIRs are running in opposite directions:

★ Replace cover on PIR and refit the retaining screw.
3.3 Door/Window Contact Detector
★ Choose the location for each magnetic contact (remembering the need to wire them back to
the Control Unit). Each contact consists of a magnetically-operated switch (with screw
terminals at the back) and a magnet in an identical housing.
★ The switch (the part with screw terminals and cable) should be mounted on the frame. The
magnet should be mounted on the door or window itself directly opposite the switch, no more
than 8mm apart when the door or window is closed (Illustration 8). Mark two mounting holes
for the magnet on the door or window and two mounting holes for the switch on the frame.
