Meat lockers, unregulated buildings in very hot or cold climates, and other areas of
extreme temperature often require space protection.
Refer to Protecting Vacation Homes and Garages in the Residential Applications
for installation instructions.
For industrial applications in very cold
environments, Sentrol manufactures the
6187CTX PIR. It operates down to
-40°C (-40°F). The 6155CT can also
be used in cold climates, but is housed in
standard plastic.
For very hot environments where the
temperature differential between a
person and the surrounding air is very
small, Sentrol offers the Sharpshooter
6155XT, which can distinguish
temperature differences as small as 1°C.
Sunlight—Avoid direct sunlight on the
plastic lens (even with UV stable plastics).
SPACE DETECTION
Temperature—The 6187CTX PIR is rated to perform from -40°F (40°C) to
+120°F (+50°C). Be aware of a temperature in excess of these specifications.
Humidity/Rain/Fog—Make sure the conduit openings are well sealed and the
mounting holes are sealed.
Birds & Animals—Depending on the size, speed and proximity to the detector,
warm blooded animals can trigger an alarm. The larger the animal, the further away
it can be detected. Mount the PIR high-at least 7 ft. (2.13m)-on a flat surface that
discourages rodents or birds from perching. Avoid directing the sensor towards
bushes or branches where birds could perch. You may consider mounting two PIRs,
one above the other, in parallel to require verification of alarm.
Weeds & Bushes—Tree branches or bushes can cause an alarm when the wind
moves them, and weeds and bushes can block detection. Keep branches and bushes
at least 30 feet (9.15m) from the PIR.
Install the PIR away from vines or vegetation that could block the view.
Testing your installation over a 24-hour period can help troubleshoot any false alarm
sources. Take the time to know your environment. Up front planning is always less
expensive than unwanted alarms later.
