1. INTRODUCTION
The SRN-2000 series of passive infrared detectors presents a
technological break-through that is revolutionizing the PIR industry.
The SRN-2000 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 service -
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
40 easy-
to-change lenses
- more than the entire combined industry
competition.
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 and effective
coverage that
saves you time and money in every installation
.
Flexibility
takes on new meaning with the SRN-2000 series. With
40
interchangeable lenses, 30° vertical and horizontal adjustments, and
surface, corner or flush mounting installation - 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.
Visonic Ltd., a leader in the field of passive infrared detection devices,
continues to develop lens technology to satisfy the expanding needs
and demands of the security industry.

If the standard No. 100 lens does not meet your coverage
requirements, refer to the SUPER-RED LENS LIBRARY and select
the pattern you need. Your nearest Visonic Ltd. distributor will be glad
to supply you with any lens that suits your particular requirements.
For UL installations, use only UL approved lenses listed at the
end of Section 4.
LENS LIBRARY
SUPER-RED offers a selection of more than 40 lens patterns 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 Wide-Angle 90
