The SRN-2000 series employs an innovative approach by
combining several different design techniques to solve the
industry's biggest problem - false alarms.
By incorporating programmable pulse counter, coverage-range
control adjustment, RF protection up to 1000 MHz, visible light
rejection filter, maskable lens patterns, background noise test
point and dual element low-noise pyroelectric detector, the
SRN-2000 does more than give lip s ervice - it truly masters the
false alarm problem.
As the only PIR manufacturer in the world to produce its own
Fresnel lens assemblies, Visonic Ltd. offers an outstanding
variety of 45 easy-to-change lenses - more than the entire
combined industry c ompetition.
Illustrated in the "Super Red Lens Library:" • 9 wide-angle
lenses up to 140. •3 long-range corridors up to 120 ft. • 6 pet
alleys. •3 finger curtains. • 8 lenses for combined ceiling and
room coverage. • 10 unique lenses for multiple 2-3 room and
corridor coverage. • 6 solid curtains. The "Super-Red Lens
Library" provides the most extensive selection of cover ages and
saves you time and money in every installation.
Flexibility takes on new meaning with the SRN-2000 series. With
45 interchangeable lenses, 30 vertical and horizontal
adjustments, and surface, corner or flush mounting installation
from 0 to 5 m (17 feet) hei ght you know SRN-2000 is the only
universal PIR you can truly standardize on... without
compromising!!!
Other features include LED selector, anti-tamper switch, silent
relay and a broad power supply range. A special material allows
masking of specific beams to eliminate potential false alarm
sources.

LENS LIBRARY
SUPER-RED offers a selecti on of more t han 45 lenses to provide
the best coverage pattern for any installation.
The SUPER-RED LENS LIBRARY is divided into the following
nine sections:
Section 1: Corner Mounting Wi de-Angle 90° - 100°.
This section comprises six lenses which provide the maximum
room coverage, when the PIR is installed in the corner.
Section 2: Ultra-Wide-Angle 120° -140°.
This section comprises three lenses which provide the largest
and widest room coverage i n applications where the PIR is wall
mounted or flush mounted.
Section 3: Pet-Alleys.
This section comprises six lenses featuring a single horizontal
beam layer which allows pets to move under the coverage
pattern, undetected.
Section 4: Long-Range Corridors up to 36 m (120 ft).
This section compri ses three lenses speciall y designed for long
range and narrow areas s uch as corridors, aisles and long walls.
Section 5: Multiple Room and Corridor Coverage.
This section c omprises ten lenses, each provi ding a combi nation
coverage of one or two Long-Range corridors and one or two
Wide-Angl e rooms simultaneously, using a single PIR.
Section 6: Combined Ceiling, Stair and Room Coverage.
This section compri ses eight lenses providing mult iple coverage
of ceiling and stairs in additi on to the normal room area c overage.
Section 7: Finger Curtains.
This section comprises three lenses providing coverage of
multiple vertical Finger Curtains which may be used to prevent
access from two walls simultaneously and detect movement
through curtains located in the area between the walls.
Section 8: Lenses for Energy Management PIRs.
This section comprises four high density lenses specially
designed for use with models SRN-2000E, ET and EF in
Energy Management applications.

SOLID CURTAIN PIR
Description
The SRN-2000H is a horizontally
mounted PIR which provides a
variety of Solid- Curtain coverages. The unit may be used to
provide wall and large s how
window coverage or as an
internal invis ible barrier to detect
movement between two areas.
Lens No. 52 is the standard lens
supplied with SRN-2000H.
Fitted with lens No. 52 this unit
produces a solid curtain coverage
extending out from the mounting
wall to the opposit e wall-up to a
maximum of 18m (60 ft) and
down to the floor (Fi g. 3).
A Pet-Alley curtain can be
created by installing the
SRN-2000H near the floor; angle
the unit 45 towards the ceiling.
The height of the curtain from the
floor can be adjusted precisely by
rotating the lens .
In addition to lens No. 52, Visonic
offers several interchangeable
lenses providing coverage
combinations of solid curtains
and beams. For more details
refer to SUPER RED LENS
LIBRARY
Mounting
The SRN-2000H should be mounted horizontally on its angular
shaped back, pointing to the floor at a declination of 45°.
The preferred location is at the wall-to-ceiling juncture. Wall or
ceiling mounting is also possible as long as the 45° angle is
maintained. (Fig. 5) .
The unit can be mounted at any height up to 18 m (60 ft),
providing the largest curtain coverage on the market -18x18 m
(60x60 ft). All lenses, except lens No. 52, require mounting the
unit with the lens to the left (when facing the unit).
Adjustment
The curtain coverage can be adjusted 10 to left or right by slidi ng
the printed circuit board against the graduated scale. Vertical
adjustment of ±15° is pr ovided by rotat ing the lens (applic able for
lens No. 52 and 56 only). In other regards, the SRN-2000H is
virtually identical to the SRN-2020.

CEILING MOUNTED PIR
The SRN-2000R is a ceiling mounted PIR.
Fitted with lens No. 55, the unit produces four finger curtains
projected from the ceiling, down to the floor.
When mounted at 3m ( 10ft) height the unit provides a patter n of
3x9m (10x30 ft) maximum (measured at floor level).
The maximum recommended mounting height is 6m (20ft)
providing a floor coverage area of 6x18m (20x60 ft) maximum.
In all other regards, the SRN-2000R is virtually identical
SRN-2000H.

To change or adjust a lens release and remove lens retainers
located on both sides of the by pushing t hem from the i nner side
of cover (Fig. 7). Insert a new lens with the grooved surface
facing out and the lens number in the upper right corner.
From inside the cover, careful ly center the lens by sliding it ri ght
or left, until it edges protrude equally at both sides.
