GENERAL INFORMATION
These passive infrared motion detectors are versatile
wall-mounted
units employing
Fresnel lenses and-
offering efficient protection patterns for commercial and
residential applications.
The detectors sense Sudden
and slight changes in temperature within the area Of
detection; thus, when an intruder crosses or enters any
zone.

reporting.
Best coverage will be
obtained if mounting is selected such that the likely
direction of intruder motion is across the pattern.
The No. 990 is equipped with a wide-angle lens, the
No. 990LR with a long-range lens. and the No. 990PA
with a pet alley lens.

Do not install where the defector is exposed to direct
sunlight or directly above strong sources
of
heat.
Make sure the detection area does nol have ob-
sIrucIions (curtains. screens, large pieces of fur-
niture. plants. etc.) which may block the pattern of
coverage.
Avoid locating a detector in areas which contain

Do not mount on an unsrable surface.
Impofianl:
Avoid running alarm wiring close to heavy-
duty electrical power cables.
PROTECTION PATTERNS
The protection patterns shown belo* can be modified
to suit the needs of a particular area by selective use of
the masking strips supplied.
