sensors trip
Alarm output: Solid State Relay. NC, 100 mA / 30 VDC, 35 ohm
maximum internal resistance. "Open" for 2 – 3 sec. in case of
alarm, masking event (applicable for DUET-AM G3 only) or
complete power failure.

DUET-AM G3 only) or complete power failure.

Masking Detection Delay: About 60 seconds
Trouble/ Masking Indication: LED alternately flashes green and

red and TRB relay opens until the detector is reset.

MOUNTING
Form: Surface or corner (no

brackets); surface, corner and
ceiling with brackets
Height: 2 - 2.6 m (6.5 - 8.5 ft)
without bracket, 2 - 3.6 m (6.5 ­12 ft) with bracket.

Note: Mounting heights of
greater than 2.6m (8.5 ft) may
reduce the detector's coverage
range.

Caution: with brackets in use,
effective detection ranges may
differ from those indicated in
Figures 2 and 8.

Optional Brackets: BR-1
(surface), BR-2 (corner) and
BR-3 (ceiling).

ENVIRONMENTAL
RFI Protection: >30 V/m up to

1000 MHz.

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.

3.3 Wiring

Refer to Figure 6 and wire up the terminal block:

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.
