Set the required sensitivity detection using DIP2 of
SW2 as follows:
ON high sensitivity detection
OFF low sensitivity detection
Note: The higher the sensitivity detection the less
movement will be necessary before the PIR
detector will trigger the alarm.
3. The setting of the DIP1 & DIP2 of SW2 can be
distinguished from the LED indication as follows:
On/Off
Selection
DIP1 of
SW2
DIP2 of
SW2
Trigger reaction of LED
High
Sensitivity
LED will be on once.
It implies high
sensitivity.
ON Walk Test
mode
Low
Sensitivity
LED will flash twice. It
implies low sensitivity.
OFF Normal
mode
High/Low
Sensitivity
LED does not light up.
In summary, the setting of DIP1 & DIP2 of SW2 is
concluded as below:
SW2 DIP1 DIP2
ON Walk Test Mode High sensitivity
OFF Normal Mode Low sensitivity
4. Connect the 1/2 3.6V Lithium battery to the battery
spring.
Note: When the battery is connected, the LED
behind the lens will flash for 2-3 minutes as
warming-up duration until the PIR has stabilized
when the LED will then stop flashing and turn OFF.
5. In normal mode, remove the rear cover of the PIR
detector. The Detector’s LED will illuminate and the
Smart Home Box should beep. It is because the
tamper switch fitted on the Detector has been
activated.
6. When the Detector is fully installed i.e. battery
cover is refitted; the Detector will not detect
movement for approximately 2 minutes after each
activation. (This feature is present to conserve
battery power and maximize the battery life).
7. In order to communicate with the Smart Home Box,
the ID code of the Detector needs to be learned by
the Smart Home Box. To proceed with ID code
learning.
a. Set the Smart Home Box into ‘3. Security
Sensor Zone’ and press .
b. Select ‘3-1 Wireless Sensor Zone’ and
press .
c. ‘Input (01-32) Sensor Zone’ and press .
d. An indication of ‘:1 Learning ID’ will be shown
and press .
By pressing tamper switch located adjacent to the
PCB on the Detector will emit the ID code to the
Smart Home Box instantly.
8. For quick start, jumper link (S2) will quick start the
battery this will take approx. 2 minutes. By
placing the jumper link (S2) into position, the LED
adjacent to the (S2) jumper link will become
illuminated, this implies the battery start up has
been completed. It is important to remove the
jumper link (S2) after this has been observed to
save battery power.
Jumper link (S2)
Note: On first battery start up, because of the
nature of the battery protection the battery may
incur a low battery status and may not start up
straight away, but will automatically start within 10
minutes.
Note: Only one of pins of Jumper link (S2) will be
inserted in position as factory default setting.
TESTING THE PIR DETECTORS
Ensure that the system is in Test Mode.
With the PIR detector set in Test mode and mounted in
position on the wall, allow 2-3 minutes for the detector
to stabilize before commencing the Walk Test.
