3. Remove the PIR from its mounting plate (activating the tamper switch).
4. Select the appropriate sensor group and number.
5. Exit the panel’s programming mode.
6. Return the PIR to its mounting plate.
Final Testing
Final testing should be done to verify radio signal integrity and confirm
control panel programming and response. The actual transmitter range can
be determined by performing a sensor test as follows:
1. With the PIR temporarily mounted at its intended location, remove the
PIR from its mounting plate and activate the tamper switch to start the
walk test mode.
2. Replace the sensor in its mounting plate.
3. Place the control panel in Sensor test mode. Move across the
detection pattern until the sensor’s LED turns on. STOP your motion.
4. Listen for the appropriate system response. Refer to the specific panel
installation manual for details on system response. If the system does
not respond as expected, proceed to the “Error! Reference source
not found.” section.
Mounting
The sensors must be incline-mounted on a wall surface or incline-mounted
in a corner at a mounting height of 7.5 ft. (2.5 m).
To Mount the Sensor
1. Remove the mounting plate by depressing the button on the top of the
sensor body. With the opposite hand pull the mounting plate away from
the body of the sensor.
2 Punch out the mounting holes that best fit your application. See Figure
3 for wall mount options.
3. See Figure 4 to determine which knockouts to use when mounting the
motion sensor. Use the outside 4 holes for corner mounting, or the
inside 4 holes for surface mounting.
Figure 4: PIR Mounting Plate Knockouts
4. Mark the location of the required holes on the mounting surface.
5. Use wall anchors and screws to secure into place. Attach the sensor to
the mounting plate.
6. When testing is completed the PIR can be securely attached to its
mounting plate by screwing the smallest enclosed screw into the hole
at the top of the mounting plate.
Setting the Sensitivity
The PIR has two sensitivity settings (standard and high sensitivity). The
sensor is set to standard sensitivity at the factory. This sensitivity is
preferred for most applications and provides the best immunity to false
alarms.
Note: If the shorting jumper is not used or is placed incorrectly, the sensor
defaults to standard sensitivity.
Figure 5: Sensitivity Pin Locations
CAUTION: High sensitivity should only be used in environments where
the room temperature is very stable.
1. Remove the mounting plate by depressing the button on the top of the
sensor body. With the opposite hand pull the mounting plate away from
the body of the sensor.
2. Locate the sensitivity pins directly above the battery when looking at
the back of the PIR
3. To change to high sensitivity, move the shorting jumper to the pair of
pins that are closer to the left side of the PIR
4. Walk test the PIR to verify the sensitivity.
The difference between the two settings are indicated in Figures 6 and
7.below.
