Motion Sensor Supplemental Information
MOUNTING LOCATION
DT-906
DT-900
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 covers and wall mounting are tamper protected. A screw must be installed in the wall
to utilize the tamper feature.
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.
Trouble Memory
Disabled: To disable INFORMER function, set S2 to the open position.
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.
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.
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.
If a self-test error is detected, the self-test LED pattern, all three LEDs flashing, replaces the INFORMER LED pattern.
Short the pads with the screwdriver again to clear the LED pattern and initiate a self-test.
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.)
Anti-Mask
The DT-900 Series anti-mask feature detects attempts to block or cover the sensor by sending an active infrared beam out into the
INPUT MODES
sensor's field-of-view, at regular 8 second intervals. If the DT-900/DT-906 is blocked or covered (i.e. with a box or fabric) the beam
The DT-900 Series accommodates several international operating requirements using two operating modes-Standard mode with is reflected back to the sensor. After two consecutive reflected beams, the sensor signals a trouble condition-green and red
remote LED enable and Command Input capability or European 2-Wire CENELEC mode (INPUT 1 and INPUT 2). For Standard LEDs flash rapidly and the mask relay opens.
Mode, remove jumper J4 and install jumper J6. For CENELEC mode, remove jumper J6 (See Figure 1).
INFORMER Conditions
Table 1 Standard Mode-J6 Installed Table 2 CENELEC Mode-J6 Removed
Table 3 describes two trouble alerts which are reported by the INFORME R circuit. To use this troubleshooting matr ix:
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.

TROUBLESHOOTING
Vertical Adjustment
Various mounting locations may require fine vertical adjustment (e.g. uneven walls or floors, etc.). During the walk-test, 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
tests are installer initiated, upon Command Input, or every hour during normal operation. A self-test error causes the Trouble relay
to open and all 3 LEDs flash unt il the problem is corrected. If the problem persists and the LE Ds continue to flash, the unit is defective
