3. INSTALLATION3. 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
Prevent direct sunlight from
reaching the detector
Do not install outdoors
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 dis tort the microwave sensor's coverage pattern.
C. If two DUET-AM C/O 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 C/O in places where one of the two
sensor circuits alarms constantly or intermittently, due to
environmental interference.
E. DUET-AM C/O 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.
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).
E.
Punch out any one of the wiring knockouts shown in Figure 5.
Figure 3. Cover Removal
F. Hold the base against the wall at the selected installation location,
mark the points for drilling and drill the holes. Insert the plastic
dowels (supplied) if necessary.
G. Pass the wires through the wiring inlets into the base and at tach
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.

IMPORTANT: To comply with CE safety requirements, connect to
CE-approved control panels with current-limited DC output.
Note: Use RTV to seal the base opening(s) to prevent insects from
entering the detector.
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 hi gh (+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 C/O 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).
Flashing green PIR walk-test detection
Steady red (1.5-5 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.

Note: Switch positions shown are factory default.
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 C/O units are
set to the FAR position.
Note: For the optional long range lens No. 34D, the vertical
scale should be in 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.
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 m aterial over the lens or put
a masking object clos e 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:

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, t wo consecutive motion
events are required to trip the PIR s ensor. For faster catch performance,
shift SW-1 to OFF. In this pos ition, only one motion event is required to trip
the PIR sensor.

C. Mount the front cover in place.
D. Walk int o 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 cov er 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 v arious ranges and verify that your
motion is consistently detected.

B. Install the front cover in place.
C. Walk across the detector’s field of view in different directions, at v arious
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").
E. Remount the cover and fasten it to the base using the small sc rew 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 mas king material on the lens or a mask ing object in front of
the lens and remove them, if found.
• Reset the detector by walk testing: cross its field of v iew at the far end,
causing it to alarm several times.
If everything is back to normal, the LE D 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.
