MOUNTING THE DETECTOR
Choose a location most likely to intercept an
intruder. See detection pattern in FIG.: 7. The
DOUBLE DUAL high quality sensor detects
motion crossing the beam; it is less sensitive
detecting motion towards the detector.
The MRX-220N performs best when provided with
a constant and stable environment.
The bracket provides MRX-220N installation on
the wall and on the pole, allows changing the
installation angle (vertically and horizontally) in
wide range (FIG.2).
AVOID THE FOLLOWING LOCATIONS
∗ Facing direct sunlight.
∗ Facing areas subject to rapid temperature
changes.
∗ Areas with air ducts or substantial air flows.
∗ Facing metal doors.
NOTE
:
Recommended installation height is 2.4m.

For LR (Long Range ) mirror optic
Group A - positions 0 and 1 – set sensitivity for 40m
detection range
Group B - positions 6 and 7 – set sensitivity for28m
detection range
Group C - positions B and C – set sensitivity for
15m detection range
The 5 or 6 levels in each group are used to set up
the sensitivity according to environment.
Each range group includes 5 or 6 setting levels
according to environmental condition risk.
For example:
If detector is used for 15m range in open space with
sunlight – set switch to position 8 or 9.
MRX–220N DESCRIPTION
The MRX-220N is a combination of DOUBLE
DUAL PIR with MIRROR optics & MW detectors,
specially designed for outdoor and harsh
environment applications.
The Mirror DOUBLE DUAL detector MRX-220N
uses varifocal mirror that improves the focus and
the level of energy received by the Pyro Sensor.
This combination assures "false alarm free"
operation.
The 16 position rotate switch changes the MW
and PIR sensitivity so that the effective pattern
will be scaled.
INSTALLING THE DETECTOR
1. To remove the front cover, unscrew the
holding screw. Insert a screwdriver between
the front and the bottom and pull gently, until
the front cover is disengaged. (FIG 1)
2. Break out the desired holes for proper wiring
as per FIG 6.
3. Insert the wire through the wire access hole,
and mount the detector base to the wall with
the necessary number of screws.
4. Access for wiring connections is very easy
with the terminal block located on the PCB.
See FIG 3.
5. Replace the cover by inserting it back in the
appropriate closing, screw the holding screw.
If the front cover of the detector is opened, an
immediate alarm signal will be sent to the control
unit.

SENSITIVITY AND RANGE ADJUSTMENT
The
calibration
of range and sensitivity is
performed by single digital 16 positional rotary
switch.
There are 3 groups of switch setting according to
detection range.
Each group is devided to levels of sensitivity
according to installation environment.
The value of sensitivity level is changed according
to optic
For WA (Wide Angle ) mirror optic
Group A - positions 0 – 5 – set sensitivity for 21m
detection range
Group B - positions 6 – A – set sensitivity for15m
detection range
Group C - positions B – F – set sensitivity for 7m
