Step 9

Unfasten screws and remove mount­ing plate from sensor. If required,
remove the knockout to allow wire
entry via electric metallic tubing or
surface wiring conduit.

Step 10

Attach mounting plate to wall at
desired height, using four screws
(not supplied).

Step 11

Install M5 (#10) screw (not supplied)
in wall 1.9 cm (3/4”) below mounting
screw, as shown, for tamper activa­tion.

Step 12

Pull about 30 cm (12”) of wire from
wall through the opening in the
mounting plate and route wire to the
terminal strip.

Step 13

Hang the sensor on the mounting
plate hooks and fasten with the two
mounting plate screws.

Step 14

Wire the
unit as
shown.

Use

0.8 - 1.5 mm
(22-16 AWG).

NOTE: Secure
wires to
mounting plate
with tie wraps.

Step 15

Loosen horizontal locking screw in
sensor support base.

Step 16

Grasp housing and rotate it to the
desired position (coarse adjust). If
fine adjust is needed see Steps 21-

23.

NOTE: Reference marks = 5° change.

Step 18

Apply power to the sensor, and all
the LED’s will start flashing rapidly.

Wait 90 seconds for the power-up
self-test to finish, at which point, if
there is no motion in the detection
area, all the LED’s will be off, and the
sensor will be ready for walk testing.

If the three LED’s do not go off after
90 seconds, refer to the Trouble­shooting section.

1.9 cm (3/4”)

Step 21

For fine horizontal adjustment, loosen
the PIR horizontal fine locking screw
on the PCB.

Step 23

Tighten the horizontal fine locking
screw on the PCB.

NOTE: Fine adjustment allows for small
changes (3 degrees right or left) between
coarse settings.

Step 22

Rotate the horizontal fine adjust knob
to the desired position.

30 cm (12”) minimum

*Factory default setting.

Step 4

Set switch S4 to establish microwave
range.

Step 17

Tighten horizontal locking screw in
sensor support base.

Step 24

Remove the jumper at J4 on the PCB
to disable the LEDs after walk­testing, and complete installation by
closing the top cover and replacing
the bottom cover.

NOTE: Fine adjust may be needed during
walk-test. (See Troubleshooting section.)

2 m (6’)

4 m (12’)

Step 20

Walk-test the sensor to check for
adequate detection coverage and to
verify the sensor is fully functional.
Depending on the selected sensitiv­ity level, the sensor will alarm after
taking between 2 and 4 steps in the
detection pattern.

NOTE: If an on-going trouble, mask or
INFORMER condition occurs, the LEDs will
display a pattern that identifies the trouble.
(See the Troubleshooting section).

Step 19

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.

If a Trouble or INFORMER condition LED pattern disappears before being noted, initiate a self test (see Self Test section),

and the sensor will show the last LED pattern stored in the sensor’s memory. To clear this display, initiate another self test.

The noted LED patterns will only occur when no motion is present in the detection pattern. For additional microwave

and PIR INFORMER mode LED information, see the Troubleshooting section.

NOTE: LED’s operate as listed only when the LED’s are enabled (see LED Enable section).

MASK FUNCTION

Normal Anti-Mask Operation

The DT900AM series features an anti-mask function that detects attempts to mask the sensor. The sensor
sends active Infra-Red beams out into the sensor’s field-of-view, and monitors for reflections from materials
that will block or cover the sensor. If the sensor registers a mask condition, it will open the mask relay and
rapidly flash the red and green LEDs. To avoid false mask alarms, follow the mounting guidelines shown in
Step 1.

Clearing an Anti-Mask Condition

Visually inspect the sensor, and remove any materials blocking the sensor’s view, and the sensor will
normally reset automatically. If the sensor remains in a Mask condition, walk test the sensor to ensure a
maximum detection range, and then cycle the sensor’s power to reset it.

LED ENABLE (Note: TS50131-2-4 Compliant)

The LED’s will only be enabled either by installing Jumper J4 or by connecting the Remote LED Enable
terminal as per the table below (see also INPUT 1 & 2 in the Product Specifications section).

High/Not Connected Low

LED’s Disabled LED’s Enabled

Remote LED Enable

NOTE: Do not fit jumper J4 at the same time as the
Remote LED Enable terminal is low, or the LED’s will
not illuminate.

SELF TEST

The sensor will perform a series of self-tests in the following instances:

• On power up

• Automatically every hour during normal operation

• On installer initiation. Self tests can be installer initiated either by momentarily short circuiting the two self
test pads on the PCB (see Figure 1), or by connecting the Remote Self Test terminal, as per the table
below. (See INPUT 1 & 2 in the Product Specifications section.)

Remote Self Test

NOTE: When a self test error occurs, the Trouble
relay will latch open and all three LED’s will flash
rapidly. If the problem persists, refer to the Trouble­shooting section.

High/Not Connected Low

Normal Operation Self Test

INFORMER MODE

The INFORMER mode is a useful diagnostic tool for identifying environmental conditions that are liable to
cause installation problems.

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.

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.

NOTE: The Mode 2 setting is not recommended. Use only if INFORMER indication is required quickly.

Disabled: To disable INFORMER function, set S2 to the open (OFF) position (factory default setting).

When an INFORMER condition occurs, the trouble relay opens, and the LEDs display an INFORMER trouble
code (see the INFORMER Troubleshooting Matrix in the Troubleshooting section).

NOTE: One LED indication does not relate to one PIR or Microwave event.

TROUBLESHOOTING (Continued)

Problem: The sensor’s PIR range is too long or short.
Explanation: Various mounting locations may require fine vertical adjustment (e.g., due to uneven walls

or floors, etc.).
Solution: 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.)

Problem: A combination of the sensor’s LED’s are flashing slowly when there is no motion in the detection area.
Explanation: INFORMER mode is selected on the sensor, and there is a potential false alarm source in the

local environment.
Solution: The table below 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.

4) If no environmental sources can be found, initiate a self test. If the sensor fails the self test,
replace the sensor. If not, relocate the sensor and re-test.

NOTE: If on entering the
detection pattern the LEDs
go off, the INFORMER LED
pattern can be retrieved by
initiating a self test. (See
Note 1 in the LED Indica­tors section.)

TROUBLESHOOTING

Problem: All three LED’s are flashing rapidly (LED’s are enabled), and the Trouble relay is activated.
Explanation: The sensor is in one of the following three conditions:

Power Up: The sensor is still warming up.
Low Voltage: The sensor’s supply voltage is too low.
Self Test Failure: The sensor has failed one of its internal tests.

Solution: Wait for at least 90 seconds for the sensor to power up, and then ensure that the power supply is
greater than 8 VDC. If the three LED’s are still flashing rapidly, the sensor is faulty and should be replaced.

Problem: The sensor’s LED’s are not illuminating.
Explanation: The sensor is not set up correctly.
Solution: Check that either the Jumper J4 is fitted or that the Remote LED Enable terminal is connected to

0V, but NOT both at the same time. If only one of these options is selected, and the LED’s still do not
illuminate, the sensor is faulty and should be replaced.
