The detector module is fitted with two sliding shutters to reduce
the detection angle of the PIR sensor only.
The curtains are fitted to the pan and tilt module as shown in
Figure 7. Each section of the detector lens gives a coverage
pattern of approximately 14 degrees.
When coverage exceeds the desired detection area, adjust the
module as required and mask off any beams, either vertically
or horizontally, to avoid unwanted detection.
Use portions of the self-adhesive silver mask applied to the
rear, smooth side of the lens. As an example for pet alley
masking refer to Figure 8. To replace the lens, begin by sliding
one side of the lens into the clips on the pan and tilt module.
After one side is secure, do the same for the opposite side
ensuring the lens is the correct orientation with the smooth side
facing in and the two rows of circles to the bottom.
Always replace the lens the correct way up to ensure exact
beam pattern coverage as shown in Figure 8.
Table 2 below summarizes typical alignment and masking
configurations.

Pulse count
Pulse count is the number of times the detector must detect a
presence before signalling an alarm.
Switch 2 ON = Pulse count 2
Switch 2 OFF = Pulse count 1 (most sensitive)
Detection LED
Switch 1 ON = Both LEDs Enabled
Switch 1 OFF = Both LEDs Disabled

Description
Microwave active
PIR active
Detection alarm
Walk test & settling time
Allow 3 minutes for the electronics to settle when power is
applied before commencing the walk test.
To enable the LEDs to carry out a walk test turn Switch 1 to
ON.
The detection LEDs will individually light each time the PIR or
microwave sensor is activated and will both light when both
PIR and microwave circuits are active; thus confirming an
alarm detection.
After walk test is complete turn Switch 1 to OFF if the LED
indication is not required.
Note: When you conduct a walk test, make sure that the front
cover is in place. Do not conduct walk tests with the cover
removed.
The range of the detector increases without the protective front
cover. Therefore the front cover must be fitted to establish the
correct beam pattern. Pan and tilt the lens module over the
field of view to obtain the correct coverage area.
