Sensitivity Increaser Function
You can use the sensitivity increaser function to increase the PIR’s detection sensitivity. To increase detection sensitivity, set the Jumper
Switch (JP4) to ON. To maintain normal detection sensitivity, set the the Jumper Switch (JP4) to OFF (Factory default).
Test Mode
The PIR can be put into Test mode by pressing the Test Button. In Test mode, it will disable the sleep timer and will enable the LED indicator
to light up every time a movement is detected. Every time the Test Button is pressed, the PIR will transmit a test signal to the Control Panel
for radio range test and enter the test mode for 3 mins. Test Mode will time out after 3 minutes..
LED Indicator
In Normal operation mode, the LED Indicator will light up in the following situations:
When movement is detected under low battery condition
When the cover is opened and the tamper switch is triggered.
When movement is detected if the Tamper condition persists.
When movement is detected under Test mode
When the Test Button is pressed under tamper condition or if PIR is under low battery.
The LED will not flash if the PIR tamper and battery are normal and PIR is not under test mode,
If the LED flashes to indicate signal transmission, it will flash twice rapidly upon receiving acknowledgement from panel.
Battery
IR-31 Series PIR Motion sensor uses Alkaline or Lithium batteries as power source:
The IR-31 model uses two Alkaline AA 1.5 V batteries as power source.
The IR-31SL model uses one CR123 3V Lithium battery as power source.
The IR-31SSL model uses two CR123 3V Lithium batteries as power source.
The PIR features low battery detection function. If low battery voltage is detected, a low battery signal will be sent to the Control Panel
along with regular signal transmissions for the Control Panel to display the status accordingly.
For each installation, the batteries are installed in by the factory before shipment with an Insulator inserted.
<NOTE>
When changing batteries, after removing the old batteries, press the Tamper Switch twice to fully discharge before inserting new
batteries.
Getting Started
Pull out the battery insulator to activate batteries.
The LED indicator will flash for 30 seconds. (The PIR is warming up). During the warm up period, the PIR
will not be activated. After the warm up period is over, the LED will turn off and the PIR will be ready for
operation.
Put the Control Panel into learning mode, refer to Control Panel manual for details.
Press the test button.
Refer to Control Panel manual to complete the learn-in process.
After the PIR is learnt-in, put the Control Panel into “
Walk Test
” mode, hold the PIR in the desired location,
and press the Test button to confirm this location is within signal range of the Control Panel, refer to
Control Panel manual to complete Walk Test.
When you are satisfied that the PIR works in the chosen location, you can proceed to mounting.
Mounting Method
The PIR is designed to be mounted on either a flat surface or in a corner situation with fixing screws and
plugs provided.
The base has knockouts, where the plastic is thinner and can be broken for mounting purpose. Two
knockouts are for surface fixing and four knockouts are for corner fixing as shown in the picture.
For corner mounting, a triangular bracket is provided to add Back Tamper Protection. The bracket also
includes two knockouts to mount on the wall.
For surface mounting, an optional rotating bracket is provided for users to adjust the range
of detection. With the rotating bracket, the IR-31 can be rotated 80 degrees horizontally and
70 degrees vertically to provide optimal coverage.
Surface mounting:
I.
Remove the fixing screw and cover assembly.
II.
Break through the knockouts on the inside of base
III. Using the holes as a template, drill holes in the surface.
IV. Insert the wall plugs if fixing it into plaster or brick.
V.
Screw the base into the wall plugs.
VI. Screw the cover onto the base.
Corner mounting:
I.
Break through the four corner knockouts.
II.
Using the four holes as a template, drill holes in the surface of the corner
III. Insert the wall plugs
IV. Screw the base into the wall plug.
V.
Screw the cover onto the base.
Corner mounting with triangular bracket:
The triangular bracket can be mounted on the wall with provides screws.
I.
Break through the two knockouts on the triangular bracket.
II.
Using the two holes as a template, drill holes in the surface of the corner. Insert wall
plugs
