MRX–220N DESCRIPTION
MRX-220N
MRX–220N FEATURES
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 mirrors that improve the focus and
the level of energy received by the Pyro Sensors.
This combination assures “false alarm free”
operation.
The detection sensitivity and range is controlled by
digital rotary switch allowing 16 calibration levels,
so that the effective pattern will be set for every
installation environment and protection site.

MOUNTING THE DETECTOR

INSTALLING THE DETECTOR
Choose a location most likely to intercept an
intruder. See detection pattern in FIG.: 6. 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.7).
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.
FIG. 1 - REMOVAL OF FRONT COVER
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. See FIG 1
2. Break out the desired holes for proper wiring
as per FIG 5.
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 2.
5. Replace the cover by inserting it back in the
appropriate closing, screw the holding screw.
NOTE:
Recommended installation height is 2.4m.

Terminal 1 - Marked “ - ” (GND)
Connect to the ground of the control panel.
Terminal 2 - Marked “ + ” (+12V)
Connect to a positive Voltage of 8.2 -16Vdc
source (usually from the alarm control unit)
Terminals 3,4 & 5 - Marked “ NC C NO ”
These are the output relay contacts of the
detector. Connect to a normally closed or
normally opened zone in the control unit.
Terminals 7 & 8 - Marked “ TAMPER ”
If a Tamper function is required connect these
Terminals to a 24-hour normally closed protective
zone in the control unit.
When an intruder is detected, alarm relays (N.O.
and N.C.) will switch for 1.8 sec.

SENSITIVITY AND RANGE ADJUSTMENT
The calibration of range and sensitivity is
performed by single digital 16 position rotary
switch.
There are 3 groups of switch setting according to
detection range.
Each group is divided 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 20m
detection range
Group B - positions 6 – A – set sensitivity for 15m

Group C - positions B – F – set sensitivity for 10m
