TROUBLESHOOTING

Vertical Adjustment

Various mounting locations may require fine vertical adjustment (e.g. uneven walls or floors, etc.). During the walk­test, if the PIR is short-ranged, turn the Vertical Adjust Screw counterclockwise. If the PIR is over-ranged, turn the
Vertical Adjust Screw clockwise.
(See Step 5.)

Self-Test

The sensor microcontroller automatically performs a series of self-tests in the following instances: when the unit is
powered up, when the tests are installer initiated, upon Command Input, or every hour during normal operation. When
a self-test error occurs, the Trouble relay opens and all 3 LEDs flash until the problem is corrected. If the problem
persists and the LEDs continue to flash, the unit is defective and must be returned for repair.

Trouble Memory

If the LED pattern disappears before you see it, you can retrieve the pattern. The trouble memory feature stores the
last LED pattern from a self-test detected problem or an INFORMER condition.

To recover the LED pattern, first open the Top Cover (see Step 2). Using a small screwdriver, momentarily short circuit
the two Self-Test pads located on the printed circuit board (see Supplemental Information, Figure 1). The trouble LED
pattern will be re-displayed.

Short the pads with the screwdriver again to clear the LED pattern and initiate a self-test.

INFORMER Conditions

Table 3 describes two trouble alerts which are reported by the INFORMER circuit. To use this troubleshooting
matrix:

1) Find the trouble alert that describes the condition of the walk-test LEDs (with no motion in the area).

2) Walk-test the sensor, carefully watching the reaction of the diagnostic LEDs.

3) Refer to the Possible Causes column of the matrix for an explanation of the way in which the
diagnostic LEDs reacted to the walk-test.

MOUNTING LOCATION

Aim the sensor toward the interior of the room, away from windows, moving machinery, and heating/
cooling sources.

Make sure the sensor has a clear line-of-sight to all areas you wish to protect. If the PIR is blocked, the
unit will not alarm.

TAMPER

The sensor cover is tamper protected.

WIRING

Reverse polarity will not damage the sensor.

Knockouts are provided to allow wire entry via 1/2 EMT or surface wiring conduit.

NOTE: For proper wiring methods, refer to the National Electrical Code NFPA 70.

INFORMER MODE

The INFORMER circuit counts the number of events registered by both the microwave and PIR
technologies, and uses the resulting ratio to determine if either technology is working properly
or is misapplied. Establish the INFORMER mode using switch S2. (See Step 7.)

Mode 1: Set S2 to position 1. In Mode 1, 32 PIR events without a microwave event will cause the
unit to go into PIR INFORMER. 128 microwave events without a PIR event will cause the unit to
go into microwave INFORMER. One LED indication does not relate to one PIR event.

Mode 2: Set S2 to position 2. In Mode 2, 16 PIR events without a microwave event will cause the
unit to go into PIR INFORMER. 16 microwave events without a PIR event will cause the unit to
go into microwave INFORMER. One LED indication does not relate to one microwave event.

NOTE: The Mode 2 setting is not recommended. Use only if fast INFORMER

activation is required.

Disabled: To disable INFORMER function, set S2 to the open position.

FCC NOTICE: This equipment has been tested and found to comply with the limits for a field disturbance sensor, pursuant to
Part 15 of the FCC Rules. The user is cautioned that changes or modifications not expressly approved by IntelliSense could void
the user's authority to operate this equipment.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of
the following measures:
 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and receiver.
 Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

 Consult the dealer or an experienced radio/TV technician for help.

IC Notice: Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device
must accept any interference, including interference that may cause undesired operation of the device.

Note: The ULC label or listed marking on a product is the only evidence provided by Underwriters Laboratories of Canada to
identify products that have been produced under the Listing and Follow-Up Service.

Indicates Detection Area

When an INFORMER condition occurs, the trouble relay opens, and the LEDs display an INFORMER trouble code.
The sensor performs a self-test within the hour to determine if the problem is internal.

If a self-test error is detected, the self-test LED pattern, all three LEDs flashing, replaces the INFORMER LED pattern.

If no self-test error occurs, the unit continues to display the INFORMER LED pattern and relay remains open. The
problem is misapplication. Walk-test the sensor to pinpoint the cause. (Refer to Troubleshooting Table 3.)

NOTE: If you enter the de­tection pattern and the LEDs
go off, you can retrieve the
LED pattern to pinpoint the
problem. Refer to Trouble

Memory above.

Step 18

Walk-test the sensor to check for
adequate detection coverage and to
verify the sensor is fully functional.
Two to four normal steps should
make the LEDs light and trigger an
alarm.

NOTE: When there is no motion in the
detection area, all three LEDs should be off.

NOTE: If an on-going self-test problem or an
INFORMER condition occurs, the LEDs
display a pattern that identifies the trouble.
See Supplemental Information (Table 3).

Step 17

Turn the microwave potentiometer
counterclockwise to decrease the
microwave range to minimum.

During walk-test, gradually turn the
potentiometer clockwise increasing
microwave sensitivity until the
desired range is obtained.
