MRX–220N DESCRIPTION
The MRX-220N is a combination of DO BLE
D AL PIR with MIRROR optics & MW detectors,
specially designed for outdoor and harsh
environment applications.
The Mirror DO BLE D AL 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.
MRX–220N FEATURES
• DO BLE D AL PYRO sensor and full pattern
mirrors for outstanding detection performance
and elimination of false alarms.
• MW detection based on Doppler concept.
• FET based DRO with strip line antenna.
• VLSI based electronics with movement speed
spectrum analysis.
• N.O. & N. C. Relays switched at the same
time.
• Height installation calibrations free from 1.5m
to 3.0m (5ft to 10ft).
• 16 levels of MW and PIR sensitivity
adjustment.
• Micro controller signal processing.
• MW and PIR sensitivity adjustment.
• Environmental immunity.
• Temperature compensation.

MOUNTING T E DETECTOR
Choose a location most likely to intercept an
intruder. See detection pattern in FIG.: 6. The
DO BLE D AL 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.
NOTE:
Recommended installation height is 2.4m.
INSTALLING T E 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. 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 bloc
k located on the PCB.
See FIG 2.
5. Replace the cover by inserting it back in the
appropriate closing, screw the holding screw.

FIG. 2 - TERMINAL BLOCK CONNECTIONS
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.
If the front cover of the detector is opened, an
immediate alarm signal will be sent to the control
unit.
Terminals 6 & 9 - Marked “ EOL ”
End of line - options.
When an intruder is detected, alarm relays (N.O.
and N.C.) will switch for 1.8 sec.
WIRE SIZE REQUIREMENTS
se #22 AWG or larger wires. se the following
table to determine required wire gauge and length.
Wire Gauge: # 22 20 18 16
Wire Length: m 205 310 510 870
Ft. 800 1200 2000 3400
LED INDICATORS
YELLOW LED - MW detection, blinking during
warm up period and self testing
GREEN LED - PIR detection
RED LED – Alarm
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
detection range
Group C - positions B – F – set sensitivity for 10m

TEST PROCEDURES
Wait one-minute for warm-up time after applying
power.
Make the test at the protected area free of moving
people. LED should be in enable position.
Walk test
1. Start walking slowly across the detection zone.
2. Observe that the red LED lights whenever
motion is detected.
3. Allow 5 sec. between each test for the detector
to stabilize.
NOTE:
Walk tests should be done at least once a year to
confirm proper operation of the detector.
