The contractor shall provide infra-red motion detectors in the areas
specified on the drawings. Contractor shall be responsible for determining
the best mounting location in each area to provide full coverage while
minimizing false alarms. Wall mount detectors shall in addition be
ceiling, or corner mountable, and shall share common mounting brackets so
that they are interchangeable. Mounting position shall be adjustable both
vertically and horizontally so that final position may be fine tuned as
required during walk-testing.
Detectors shall employ multi-level
signal processing and temperature compensation for accurate detection,
“even in warm environments”. They shall have high immunity to false alarms
from RF, static, electrical transients, and white light.
All
detectors shall carry a 5 year manufacturer’s warranty.
Motion
detectors for each area shall be selected from the following to best match
the coverage requirements of each area :
Bravo2 For small areas, detectors shall
have 4 interchangeable lenses to provide 40' L x 40' W (12.2 x 12.2m) wall
to wall coverage with or without pet alley, 70' L x 6' W (21.3 x 1.8m)
corridor coverage, and 40' L x 3.5' W (12.2 x 1.1m) curtain
coverage.
Bravo3 For larger
commercial / residential areas, detectors shall have 4 interchangeable
lenses to provide 50' L x 60' W (15.2 x 18.3m) wall to wall coverage with
or without pet alley, 120' L x 10.5' W (36.6 x 3.2m) corridor coverage,
and 50' L x 4.4' W (15.2 x 1.3m) curtain coverage.
Bravo4 For areas where there are abnormally
severe or highly changeable environmental conditions, detectors shall have
a quad element low noise sensor. Detectors shall have 4 interchangeable
lenses to provide 50' L x 60' W (15.2 x 18.3m) wall to wall coverage with
or without pet alley, 60' L x 5' W (18.3 x 1.5m) corridor coverage, and
50' L x 4.4' W (15.2 x 1.3m) curtain coverage.
Bravo6 For areas where maximum immunity to
false alarms caused by pets is required, without a reduction in the
ability to detect people, detectors shall have dual PIR sensors employing
high density digital analysis and multi-level signal processing with a
vertically interleaving beam pattern. Detector shall provide 40' L x 50' W
(12.2 x 15.2m) wall to wall coverage.
