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 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 45 easy-to-change lenses - more than the entire
combined industry competition.
Illustrated in the "Super Red Lens Library:" • 9 wide-angle
S
. •3 long-range corridors up to 120 ft. • 6 pet
lenses up to 140
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 coverages and
saves you time and money in every installation.
Flexibility takes on new meaning with the SRN-2000 series. With
45 interchangeable lenses,
adjustments, and surface, corner or flush mounting installation
from 0 to 5 m (17 feet) height 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.
