Indoor Motion Sensor Lens Replacement

Note

If the shorting jumper is not used or placed incorrectly, the sensor defaults to stan- dard sensitivity.

1.To change the lens, first remove the sensor from its mounting plate by depressing the button on the top of the sensor.

2.Remove the cover by depressing the two tabs on the top and the one tab on the bottom of the sensor body and sliding the cover off (see Figure 8).

3.Remove the installed lens by gently placing pressure on the lens from the outside of the lens.

4.Replace with the appropriate lens by aligning its notches with the appropriate tabs in the cover.

5.Install the new lens with the smooth side facing out and the grooved side facing in.

6.Replace the cover and then replace the sensor in its mounting plate.

Animal Alley Lens Guidelines

The optional animal alley lens (part #60-709) provides protection in installations where pets move about freely. See Figures 2 and 4 for coverage.

•Allowed mounting height is between 3 and 5 feet.

•Be sure to use the flush-mount position or the corner mount position with the back of the PIR parallel to the walls. Do not use the inclined mount position since this would tilt the PIR’s field of view downward.

•Position the sensor to have a clear line of sight across the protected room.

•For best results, install the sensor higher than the highest point that the pet might reach in the detection area.

•If the detection area contains furniture or other objects upon which the pet could climb or jump, either remove these objects, mount the PIR a safe distance above these objects, or mask these areas.

Setting the Sensitivity

The PIR is set to standard sensitivity at the factory. This sensitivity is preferred for most applica- tions and provides the best immunity to false alarms.

!High sensitivity should only be used in extremely quiet environments where thermal transients are not expected.

Caution

1.Locate the sensitivity pins by first removing the mounting plate and the sensor cover as described in steps 1 and 2 of the Lens Replacement process.

HIGH

Figure 7. Sensitivity Pins Locations

2.Locate the sensitivity pins under the battery on the right side of the PIR when looking at the front of the PIR.

3.To change to high sensitivity, move the shorting jumper to the pair of pins that are closer to the top of the PIR (see Figure 7).

4.Walk test the PIR to verify sensitivity.
