3. INSTALLATION

3.1 Installation Tips

To minimize false alarms:

Do not aim at heat sources

Mount on solid, stable surfaces

Do not expose to air drafts

Do not install outdoors

2 DE1812

Prevent direct sunlight from

reaching the detector

Keep wiring away from
electrical power cables

Do not install behind partitions

In addition, a few important rules must be observed while selecting a
mounting location:
A. Microwave radiation passes through glass and non-metallic walls.

Be sure to adjust the MW range so that it does not exceed the
room limits, or else motion in the next room or moving traffic along
the outer side of the wall will cause the MW sensor to trip.

B. Large reflecting objects (especially metals) in the coverage area

can distort the microwave sensor's coverage pattern.

C. If two DUET-AM units are installed in the same room or on

opposite sides of a shared wall, they should not face each other
and must be mounted at least 2 meters apart.

D. Do not install the DUET-AM in places where one of the two sensor

circuits alarms constantly or intermittently, due to environmental
interference.

E. DUET-AM users are advised to mount the unit in locations

where inadvertent approach to less than 1 m (3 ft) from the
detector is unlikely to occur.

3.2 Mounting

A. Remove the front cover as shown in Figure 3.

IMPORTANT: When re-mounting the cover, remember to fasten the
screw well - this will force the tamper switch actuator upon the tamper
switch and will press it fully in.

Figure 3. Cover Removal

B. Loosen the vertical adjustment screw, slide the PCB up and

remove it via the “keyhole” (see Figure 4).

C. Put the PCB aside until required again.
D. Refer to Figure 5 and punch out the mounting knockouts at

the rear of the base (for surface mounting) or at the angled
sides (for corner mounting). For DUET-AM G3, punch out also
the back tamper screw knockout.

E. Punch out any one of the wiring knockouts shown in Figure 5.

F. Hold the base against the wall at the selected installation location,

mark the points for drilling and drill the holes (For DUET-AM G3,
also mark and drill hole for back tamper switch screw). Insert the
plastic dowels (supplied) if necessary.

G. Pass the wires through the wiring inlets into the base and attach

the base to the wall using the screws (supplied).

H. Return the PCB to its place within the base.

I. Proceed to wire the terminal block as instructed in Para. 3.3.

TST INPUT LOGIC

The dual color LED may be enabled remotely for walk testing with a
test switch connected to the TST input as shown in Figure 6:

TST input grounded - LED active

TST input floating or high (+12V) - LED inactive (unless mode

switch 2 is ON).

3.4 The Power-up Process

After connecting the (+) and (–) terminals to the power source, the
DUET-AM starts a 60-second warm-up period, indicated by alternate
flashing of the green and red lights.

Caution! If the alternate flashing of the red and green lights does not
stop within 60 seconds, a failure has been detected by the self-test
circuitry or, if mode switch 3 is set to ON, the unit may be masked
(refer to Para. 3.5).

3.5 What Happens in Case of Masking?

Attention! The following procedure is true only while mode switch 3
is in the ON position.

If an attempt is made to stick masking material over the lens or put a
masking object close to the lens, a trouble alert will result about 60
seconds after masking:

• The LED will flash red and green alternately;

• The TRB relay will open and will remain so until masking is

removed and the detector is reset (see Para. 3.13 for
procedure).

3.6 Visual Indications

The dual color LED is used to signal various alarm and trouble
messages as shown in Table 1 below:

Table 1. Interpreting the Visual Indications

Visual Indication

Significance

None No detection
Steady green (5 seconds) MW walk-test detection
Flashing green PIR walk-test detection
Steady red (5 seconds) Alarm: MW + PIR detection
Flashing red and - Trouble is being detected (or

green (alternately) masking if mode switch 3 is ON)

- Initial warm-up routine (stops 60

seconds after power up).

Notes:

1. During walk testing, the green light glows steadily (MW detection)
or flashes (PIR detection), depending on which one of the two
sensors discovered the movement first. Upon subsequent discovery
of the movement by the other sensor, the green light goes off and
the red light glows (alarm).

2. If the LED maintains alternate red and green flashing beyond the
warm-up period, a malfunction has been diagnosed (or, if mode
switch 3 is ON, the detector may be masked).

3.7 Mode Selector

The DIP switch mode selector is mounted on the unit’s PC board
(see Figure 4). It controls four functions as demonstrated in
Figure 7.

3.8 Vertical Adjustment

The vertical adjustment scale for the PIR sensor is located at the
upper right edge of the PC board (refer to Figure 4). Three positions
are available - FAR, MID and NEAR. All new DUET-AM units are set
to the FAR position. To adjust, loosen the vertical adjustment screw,

slide the PC board along the vertical slot until the pointer indicates the
required position on the scale (see Figure 8). When done, tighten the
adjustment screw firmly.

Figure 8. Vertical Adjustment

Caution! With swivel brackets in use, the effective detection
ranges may differ from those indicated in Figures 2 and 8.

3.9 Setting the Motion Event Counter

If you wish to set the PIR sensor for maximum false alarm
immunity, shift DIP switch No. 1 (SW-1) to ON. In this position, two
consecutive motion events are required to trip the PIR sensor. For
faster catch performance, shift SW-1 to OFF. In this position, only
one motion event is required to trip the PIR sensor.

3.10 PIR Walk Test

A. Rotate the MW RANGE control fully counterclockwise to MIN.
B. Make sure that the LED is enabled, either by setting mode

switch SW-2 to ON or by grounding the TST input.

C. Mount the front cover in place.
D. Walk into the detector's field of view at the expected far edge

of the coverage area. The green light should flash for up to 5
seconds each time your motion is detected.

Note: If the LED lights green steadily for up to 5 seconds,

your motion has been detected by the MW sensor.

E. If PIR detection is not obtained at the far end of the coverage

area, remove the front cover and re-adjust the vertical
position. Replace the cover and retest.

3.11 MW Walk Test

A. Remove the front cover.
B. Verify that the MW RANGE control is set fully counterclockwise

to MIN and enable the LED either by setting mode switch SW-2
to ON or by grounding the TST input.

C. Start by moving into the coverage area at the far edge. The

LED should light green for up to 5 seconds each time your
motion is detected.

D. If your motion was not detected at the far edge, advance the

MW RANGE control slightly clockwise toward MAX and try
again until your motion is detected reliably at the far edge.

Caution! The MW detection range must not exceed the far
edge of the desired coverage area.

E. Walk across the coverage area at various ranges and verify

that your motion is consistently detected.

Note: MW LEVEL CONTROL (see figure 4) may need to be set to
maximum for achieving maximum area coverage.

3.12 Alarm Walk Test

A. Make sure that the LED is enabled, either by setting mode

switch SW-2 to ON or by grounding the TST input.

B. Install the front cover in place.
C. Walk across the detector’s field of view in different directions,

at various distances from the detector, and verify proper
alarming throughout the detector's coverage area (the LED
lights red for 1.3 to 5 seconds).

D. When done, disable the LED by setting set switch SW-2 to

OFF or by disconnecting the TST input (leaving it "floating").

4 DE1812

E. Remount the cover and fasten it to the base using the small

screw at the bottom.

Attention! To assure proper function of the detector, the range
and coverage area should be checked at least twice a year.
Furthermore, it is recommended that users perform a walk test
at the far end of the coverage pattern to assure an alarm signal
prior to each time the alarm system is armed.

3.13 Resetting after Trouble

If trouble occurs while mode switch 3 is ON, proceed as follows:

• Search for masking material on the lens or a masking object in
front of the lens and remove them, if found.

• Reset the detector by walk testing: cross its field of view at the
far end (for DUET-AM G3 at 3m), causing it to alarm several
times (for DUET-AM G3, 3 times).

If everything is back to normal, the LED should stop flashing, and
the TRB relay should revert to the closed circuit state.

Note: If walk testing does not cause the trouble alert to stop and
mode switch 3 is ON, recheck for masking. Once masking is

ruled out, the trouble must be due to faulty PIR or MW circuitry.
