Position the front cover (see Fig. 7) in the detector housing, the
small latches aligned with their corresponding latch holders. Push
the front cover gently until a click is heard. The lens assembly,
which is located behind the front cover, is adjustable vertically.
Locking screws are provided to secure the lens assembly after
vertical adjustment and to hold the detector in the electrical box.
Opening the detector:
Using a screwdriver, release the cover by gently pushing on the
latches from the rear of the detector housing, until the front cover
disengages.

&KDQJLQJ/HQVHV
Fig. 8 shows parts and construction of MR-4000 Lens Assembly.
Note: The Positioning Guides of model MR-4000R are slightly
different from model MR-4000 and are located on the sides of the
lens housing - see Figure 11. To change or adjust a lens, release
and remove the two lens-locking clips, located on both sides of the
lens, by pushing them from inside the cover (see Figure 9).
Install the new lens with the smooth surface outside and the lens
number held at the upper left corner, opposite the lens positioning
pointer - see figure 8. From inside the lens assembly, carefully
center the lens by sliding it to the right or left. The lens is
centered when both lens edges emerge equally above the frame
of the lens housing.
Holding firmly in place, insert the lens locking clips from the
outside (flanges pointed outward) and firmly push into place until
a click is heard - see Figures 8 and 10.
Before closing the detector, the lens assembly should be held in
the correct position relative to the detector. The positioning
guides and the pointer of the lens assembly assure correct
positioning of the lens assembly relative to the front cover. Figure
11 shows the lens housing positioning of both models: MR-4000
and MR-4000R.
Model MR-4000:
The pointer is placed
close to "A" (imprin-
ted on the inner side
of the cover).
Model MR-4000R:
The pointer is placed
close to "B". The two
guiding studs assure
correct positioning of
the lens assembly in
each model and
allow movement of
the lens assembly for
vertical adjustment.

A. The MR-4000 detector is much more sensitive to motion
crossing the beams of its coverage pattern than to motion
towards or away from the detector. Therefore, select the
mounting location so that the expected motion of an intruder will
cross the beams of the selected pattern.
NOTE: Passive infrared detectors are sensitive to changes in
infrared energy caused by an object moving across the unit's field of
view. The changes in infrared energy, detected by a PIR, depend
on the amount of infrared energy transmitted by the moving object.
The changes also depend on the temperature difference between
the object and the background. As a result, the PIR may fail to
respond under certain temperature and background conditions, in
which the temperature difference is too small. It is therefore
recommended that the PIR be aimed towards the coolest place in
the protected area, to obtain the maximum sensitivity in installations
where high ambient temperatures are expected.
B. Select the most convenient mounting height. An adjustment table
determines the recommended angle for any combination of range
and mounting height (see Table 1). Remember that unprotected
areas directly above and below the detector increase when the
covered area is increased.
C. Where pets are present, consider the use of lens No. 5 (Pet
Alley). For best detection performance install the MR-4000 at
the lowest possible height that enables directing of the pattern
above the level of the pets' activity.
D. MAGIC-RED is extremely immune to air turbulence and RFl
interference. However, to minimize false alarms, it is highly
recommended to avoid aiming the detector at heaters, sources
of bright light, or windows subjected to direct sunlight. Also
avoid running wiring close to high-power electrical cables.

A. The MR-4000 is a flush mounted PIR designed to fit into
virtually any standard single-gang electrical switch box (Figure
7). The box shouldbeinstalled per its specific instructions.
B. Due to its sealed design, the MR-4000 can also be installed
directly into a prepared space in the wall, without requiring a box
enclosure. Figure 12 provides an actual size cutout drawing
which may be used when drilling the holes in the wall.
:LULQJ
Use 22 AWG or larger wires. The maximum wiring length
between the unit and its power source depends on the number of
units connected in parallel and the wire gauge.

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.

.
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°.

4DE1141
Vertical adjustment is performed as
follows:
• First, refer to table 1 and determine
the correct scale setting according to
unit’s mounting height and the
required coverage range. The table
should be used only to the maximum
coverage range of the selected lens,
as indicated in the Lens Selection.
• Slightly loosen the two locking
screws which fasten the unit to the
mounting box until the lens assembly
can be positioned up and down (with
slight friction) between the front
cover and the detector housing.
• Moving the lens assembly up or
down, set the adjusting scale to the
correct setting according to table 1
and tighten the two screws firmly.
Beam Masking Material
Special beam masking material,
supplied with each MAGIC RED sensor
can be used to mask individual
segments in the lens array which are
exposed to potential sources of false
alarm (heaters, blowers, pets etc.).
The material is transparent to visible
light but blocks infrared energy. To
block individual beam(s), locate the
corresponding segment(s) in the array.
Figure 16 .
Setting
the Vertical Scale
Cut the masking material to the exact dimensions of the
segment(s) to be blocked, remove the backing paper and apply
the masking material accurately to the inside (grooved) surface of
the appropriate segment(s). In some cases, more than one layer
of the lens masking material may be required to completely block
the infrared energy.
6HWWLQJWKH3XOVH&RXQWHU
Model MR-4000 is equipped with a programmable pulse counter
which can be set to count 1 or 3 pulses, before activating the
alarm relay. To set the pulse counter, place the jumper at the
desired setting (1 or 3) - see figure 15.
3 pulses: This setting provides the maximum protection against
false alarms caused by all types of environmental disturbances. 3
pulses may be selected for wide-angle, multi-beam lenses 1, 4
and 5.
Note: Do not select 3-pulse operation when using lenses 2 or 3.
When the pulse counter is set to 3, no alarm will occur unless the
unit registers three pulses within approximately two minutes. This
ordinarily requires crossing more than one beam (each dual-
beam produces two pulses - one additional beam element must
be crossed to provide the third pulse).
1 Pulse This setting actually disables the pulse counter. It should
be used when necessary to trigger an alarm on the first detected
pulse, such as with long-range lenses. One pulse should be
selected with lenses 2 and 3, or in high security installations
when fast "catch" performance is of greatest importance.
Self-Adjusting Walk-Test Override
The unique pulse counter incorporated in the MR-4000 features
an automatic switchover to single-pulse mode during walk-
testing. After alarm signaling, the pulse counter converts
automatically to single-pulse setting for several seconds. During
this time period each detection pulse will activate an immediate
alarm. This feature enables convenient walk-testing of each
beam in the coverage pattern - exactly as for a unit without a
pulse counter. Two minutes after the walk-test ends, the pulse
counter returns automatically to its original setting and is ready
for a new counting sequence.
)LQDO7HVWLQJ
A. Apply 12 VDC and allow 5 minutes for the unit to stabilize.
B. Adjust the vertical pattern angle according to Table 1.
C. Set pulse counter per Para. 3.7
D. MASK beams which face potential sources of false alarm.
E. Slowly walk-test the whole protected area across coverage
beams while observing the LED. The LED lights whenever
you enter or exit coverage beam. Allow a 5-minute interval
between tests for the unit to settle down.
F. Check the operation of the alarm relay and the tamper switch.
Warning: After walk testing disable the LED by setting the
LED selector to OFF.
Important: Whenever you open and close the detector,
make sure that the scale is adjusted to the correct setting
and that the locking screws are firmly tightened, so that the
position of the lens housing cannot be changed.
0DLQWHQDQFH
Proper operation, range and coverage pattern should be checked
at least once a week according to Para. 3.8. To assure proper
continuous operation, the end user should be instructed to walk
through the entire coverage pattern and to assure an alarm
output each time before the alarm system is armed.
