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.
