INSTALLATION HINTS
The DUOGUARD may be either wall or corner
mounted by applying different knockouts. The MB-95
or MB-99 mounting bracket can be applied for ceiling
or wall mount. Corner mount is generally
recommended for optimum detection.
Do not install where the detector
is in or facing direct/reflected
sunlight, windows onto main
roads (car head lights) or strong
draughts / heaters.
Ensure that there are not any
obstructions (plants, screens,
furniture etc.) in the field of view
which may cause incorrect cover/
operation of the detector.
Avoid locating the detector in
areas which contain equipment
that may change the environment
temperature rapidly.
Locate the detector at least 1
meter away from any illumination
to avoid possible interference to
microwave sensor.
)
Avoid running alarm wiring close to mains cables !!!

INSTALLATION & WIRING
Installation
1. Open the front cover by loosening the locking
bolt at the bottom of the case.
2. Remove the printed circuit board from the base of
the unit, by bending the P.C.B clips gently
upwards (handle printed circuit board with care).
3. Punch out the required knockouts and mount the
unit base to the wall, corner or bracket.
4. Lead the cable through the access hole and then
refit the printed circuit board.
5. Connect the wires to the respective terminals
according to the wiring instructions.
6. Replace the front cover after completing the
wiring and carry out a through walk test.

WALK TEST & ADJUSTMENT
It is necessary to carry out a thorough
walk test of the detector to ensure that
the correct coverage is being achieved
and no over spill of the microwave is
occurring. Also to ensure that both PIR & microwave
are working to the same detection area.
The PIR range sensitivity is not adjustable. Accurate
setting of the microwave is achieved by careful
adjustment of the microwave range controller on the
front of the PCB, next to the PIR detector, the range is
increased by turning the pre-set in clockwise direction.
When you are satisfied with your setting, all of the
LEDs may be disable from jumper switch (please
retain for future walk testing).
)Regular walk testing must be carried out, as part of
your routine maintenance visits or at least once a
year.)
MOTION SIGNAL DISCRETION
The MSD (Motion Signal Discretion) circuit recognizes
the difference between motion and non-motion signals.
Alarm output is only generated when motion is
detected by infrared & microwave sensor and
analyzed by the MSD circuit. MSD circuit ensures
supreme reliability even when environmental
conditions are severe.
