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 fi gure 11. To change or adjus t a lens, release
and remove the two lens-lock ing cli ps, loc ated on both s ides of the
lens, by pushing them from inside the cover (see fig. 9).

Install the new lens with the s mooth sur face outs ide and the lens
number held at the upper left corner, opposi te the lens positioning
pointer - see figure 8. From inside the lens assembly, c arefully
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 outwar d) and firmly pus h into place until
a click is heard - see figures 8 and 10.

Before closing the detector, lens assembly should be held in
correct position relative to detector. Positioning guides and
pointer of lens assembly assure correct positioning of the lens
assembly relative to the front cover. Figure 11 shows lens
housing positioning of both models: MR-4000 and MR-4000R.

pointer is plac ed close
to "A" (imprinted on

correct positioning of
the lens assembly in
each model and allow
movement of the lens
assembly for vertical

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 the expect ed mot ion of an int ruder wil l
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 the mov ing 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 vit y i n ins tall ations
where high ambient temperatures are expected.

B. Select the most convenient mounti ng height. An adjust ment table

determines the recommended angle for any c ombinati on of range
and mounting height (see Table 1). Take in consideration that
unprotected areas exist directly above and below the detec tor and
increases when covered area is increased.

C. Where pets are present, cons ider 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 rect ing of t he patter n
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, sourc es
of bright light, or windows subjected to direct sunlight. Also
avoid running wiring close to high-power electrical cables.

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 well
secured to the mounting box and that no excess pressure is appli ed
to the tamper switch .

Horizontal Adjustment

MAGIC-RED coverage pattern can be adjusted horizontally
approximately ± 7.5°, by rotating the l ens to the left or right side.
To adjust, remove the lens locking clips, rotate the lens to the
desired positi on and lock the lens i n 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 t he 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 im printed on the lens assembly in
two parts. Settings from 0° to -6° are imprinted on the frame
below the lens and settings f rom 6° to - 12° are imprint ed on the
frame above the lens - see figures 1, 2, 8 and 9.

Beam Masking Material

A 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.

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 on the
desired setti ng (1 or 3) - see fi gure 16.
3 pulses: This sett ing provides the maximum protection agai nst
false alarms c aused by all types of environmental dis turbances.
Three pulses may be selected for wide- angle, multi beam lens es
1, 4 and 5.

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

When the pulse count er is set to 3, no alar m will occ ur unles s t he
unit register s thr ee pulses wit hin approximat ely two mi nutes. Thi s
ordinarily requires crossing more than one beam. (Each
dual-beam produces two pul ses. One additional beam el ement is
needed to provide the third pulse).

1 Pulse This setti ng actual ly dis ables the puls e counter . I t shoul d
be used when it is necessary to activate an alarm on the first
detected pulse, such as with long-range lenses. One pulse
should be selected when us i ng lens es 2 and 3, or i n hi gh sec ur it y
installations when fast "catch" performance is of greatest
importance.

Self-Adjusting Walk-Test Over ride

The unique pulse counter i ncorporated in the MR-4000 features
an automatic override to single-puls e mode during walk-testing.
After alarm si gnaling, the puls e counter conver ts automati cally to
single-pulse set ting for several seconds. Dur ing this time period
each detection pulse will activate an immediate alarm. This
feature enables convenient walk-testing of each beam in the
coverage pattern - exact ly as for a unit without a puls e counter.
Two minutes after the end of walk-testing the pulse counter
returns automatic ally to its original s etting and is ready for a new
counting sequence.
