The table below provides maximum wiring length for a single unit,
using different gauge wires. If two or more units are connected in
parallel, the maximum wiring length indicated in the table should
be divided by number of units.

Relay connection
Connect Relay N.C. terminals (pins 1 &
2) to a normally closed burglar protection
zone of the control panel. Relay contacts
(rated at 100 mA, 30 VDC max., resistive
load only) open when an intruder is
detected or during power loss. An
18-ohm resistor is internally connected in
series with the relay contacts.
Figure 13. Plug-In
Connector Wiring
Supply Voltage connection
Connect the 12 VDC (–) and (+) terminals (pins 3 & 4) to a 9-16
VDC source. Check for correct polarity. The power source should
have a back-up battery that is capable of supplying power for at
least four hours of operation during power failure. Current drain of
each sensor is approximately 20 mA.
Plugging in the Connector
Plug the connector into the connector pins in the unit (Fig. 14).
Verify that:
A . The connector is mounted in the correct position - i.e., the
+12 VDC wire is plugged into pin 4.
B. The connector is
installed to the
end of its pins.
Tamper Switch
(optional)
Tamper switch module
TS-1 must be installed
first (see Figure 14).
Connect Tamper TS-1
terminals to a normally
closed 24-hour protec-
tion zone of the control
panel. Tamper contact
will open when the
cover is removed.
Figure 14. Mounting the Connector and
the Optional Tamper Switch TS-1
Important! For proper operation of the tamper switch, the gap
between the back wall of the installation box and the tamper switch
lever (in depressed position) must be filled with material. In this
manner, the tamper switch is depressed when unit is installed in the
mounting box. For this purpose, attach a piece of wood to the back
wall of the mounting box, just behind the location of the tamper
switch. Afterwards, carefully adjust the height, by trimming the
wood, until MR-4000 can be installed into the box and the tamper
switch functions properly. Make sure the piece of wood is reliably
secured to the mounting box and that no excessive pressure is
exerted on the tamper switch.

MR-4000 provides the most powerful tools for quick, easy and
accurate pattern adjustments. The LED selector, horizontal
adjustment, vertical calibrated scale, height selection table and
beam masking material are all unique features which enable
precise pinpointing of the pattern both vertically and horizontally.
LED Selector
The LED selector is a
3-pin connector with a
jumper to switch the walk
test LED ON or OFF - see
Figure 15.
ON is used for walk-test.
The LED lights for a few
seconds whenever motion
is detected.
OFF is used to disable the
LED after testing, to
prevent unauthorized
persons from tracing the
coverage pattern.
Figure 15 . PCB Layout
Horizontal Adjustment
The MAGIC-RED coverage pattern can be adjusted horizontally
approximately
±
7.5
°
, by rotating the lens to the left or right side.
To adjust, remove the lens locking clips, rotate the lens to the
desired position and lock the lens in place.
Vertical Adjustment
The vertical adjusting scale (printed on the lens assembly), indicates
the angle (in degrees) between the upper layer of the coverage
pattern and the horizontal line of the unit. The scale enables pattern
adjustment from 0
°
to -12
°
downward according to the installation
height and the required coverage range.
The vertical adjusting scale is imprinted on the lens assembly in
two parts. Settings from 0
°
to –6
°
are imprinted on the frame
below the lens and settings from –6
°
to –12
°
are imprinted on the
frame above the lens - see Figure 16.
Setting of the vertical adjusting scale is done by aligning the edge
of the rectangular opening in the front cover with the line marked
with the appropriate number on the scale - see Figure 16. Table 1
gives recommended scale adjustment for combinations of
mounting height and coverage distance.
Table 1 - Vertical Adjusting Scale
Example: If you require coverage range of 9 m (30 ft) and wish to install the
sensor at a height of 1.8 m (6 ft) from the ground, set the Vertical Adjustment
Scale to -6
°
.
WARNING: Maximum range as stated for each lens type
shall not be exceeded!
Note!
For MR-4000R,
the cutout
drawing should
be rotated 90
°
.
