3. DIP 4 of SW3 is used to configure the PIR Detector for walk test mode, which allows 

the operation of the Detector to be checked during installation without triggering a 

Full Alarm.

DIP 4 of SW3

Mode

Trigger reaction on LED

ON

Walk

Test

•  LED single flash when 

movement detected: implies 

the sensor is set to high 

sensitivity

•  LED flashes three times and 

illuminates once: implies 

the sensor is set to low 

sensitivity

OFF

Normal 

Position

LED will not light up (unless the 

battery in the PIR is low)

Note:

 On initial installation the PIR Detector should be set to Walk-Test mode ready 

for testing.

4. The  PIR  Detector  incorporates  a  sensitivity  feature  designed  to  compensate  for 

situations where the Detector  may  be  affected  by  environmental  changes, (e.g. 

insects, air temperature, etc). This feature is called “Detection Sensitivity” and may 

be set to Standard or High Sensitivity.

Note:

 The higher the sensitivity the less movement will be necessary before the 

PIR Detector will trigger the alarm.

The recommended setting is Standard Sensitivity. If set to High Sensitivity, in some 

cases  extreme  environmental  problems  could  cause  unexplained  false  alarms. 

If this is experienced it may be necessary to reset the PIR Detector to Standard 

Sensitivity.

Set the required detection sensitivity using DIP 5 of SW3 as follows:

OFF

Standard Sensitivity

ON

High Sensitivity

5. Connect the PP3 alkaline battery to the battery clip.

Note:

 When the 9V alkaline battery is connected, the LED behind the lens will flash 

for -3 minutes until the PIR has warmed-up and stabilized. The LED will then stop 

flashing and turn OFF.
