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 s o that t he expected mot ion of an int r uder wi ll
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, detec ted by a PIR, depend
on the amount of infrared energy transmitted by t he moving object.
The changes also depend on the temperature difference bet ween
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 sensiti vi ty in ins tal lati ons
where high ambient temperatures are expected.

B. Select the most convenient mounting height . An adjustment table

determines the recommended angle for any combinat ion 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, consi der the use of lens No. 5 (Pet

Alley). For best detecti on performance inst all the MR-4000 at
the lowest possible height that enables di rec ting of the patt ern
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 detec tor at heater s, sour ces
of bright light, or windows subjected to direct sunlight. Also
avoid running wiring close to high-power electrical cables.

manner, the tamper switch is depressed when unit is installed in the
mounting box. For this purpose, attach a piece of w ood 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 inst alled 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

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 t he
LED after testing, to
prevent unauthorized
persons from tracing the
coverage pattern.

Horizontal Adjustment

The MAGIC-RED coverage pattern c an be adjusted horizontally
approximately ± 7.5°, by rotating the lens to the lef t or right si de.
To adjust, remove the lens locking clips, rotate the lens to the
desired position and lock the lens in place.

Vertical Adjustment

The vertical adjust ing scale ( printed on t he lens as sembly), indicates
the angle (in degrees) between the upper layer of the coverage
pattern and the horizontal line of the unit. The scale enabl es pattern
adjustment from 0° to -12° downward according to the installation
height and the required coverage range.

The vertical adjust ing scale is i mprinted on the lens assembly i n
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 vert ic al adjus t ing s c al e is done by ali gni ng the edge
of the rectangular opening in t he front cover with the li ne marked
with the appropriate number on the scal e - see Fi gur e 16. Tabl e 1
gives recommended scale adjustment for combinations of
mounting height and coverage di stance.

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

mounting box until the lens assembl y
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 s egment(s) in the array.

Setting

Cut the masking material to the exact dimensions of the
segment(s) to be bl ocked, remove the backing paper and apply
the masking material acc ur atel y t o the i ns ide ( grooved) s ur fac e of
the appropriate segment (s). In s ome cases, more t han one layer
of the lens maski ng material may be requir ed to complet ely bl ock
the infrared energy.

Model MR-4000 is equipped with a programmable puls e 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 set ting provides the maximum protection agai nst
false alarms c aus ed by all t ypes of envi r onmental dis t urbanc es . 3
pulses may be selected for wide-angle, multi-beam lenses 1, 4
and 5.

Note: Do not select 3-pulse operat ion when using lenses 2 or 3.

When the pulse count er is s et to 3, no alarm will oc cur unles s t he
unit register s thr ee puls es wit hin approximat ely two mi nutes . Thi s
ordinarily requires crossing more than one beam (each dual­beam produces two puls es - one additional beam element must
be crossed to pr ovide the third pulse).

1 Pulse This setti ng actual ly dis ables the puls e count er. I t shoul d
be used when necessary to trigger an alarm on the fi rst detec ted
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" per formance is of greatest importance.

Self-Adjusting Walk-Test Override

The unique pulse counter i ncorporated in the MR-4000 features
an automatic switchover to single-pulse mode during walk­testing. After alarm signaling, the pulse counter converts
automatically t o single-pulse setti ng for several sec onds. 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.

A. Apply 12 VDC and allow 5 minutes for the unit to stabilize.
B. Adjust the vertical patter n 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. Chec k the operation of the alarm relay and the tamper switch.

Warning: After walk t esting disable the LED by setti ng 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 locki ng screws are firmly t ightened, so that t he
position of the l ens housing cannot be changed.

Proper operation, r ange and coverage pat ter n should be c hecked
at least once a week ac cording to Para. 3.8. To assure proper
continuous operation, the end user should be inst ructed to walk
through the entire coverage pattern and to assure an alarm
output each time before the alarm system is armed.
