MOUNTING A PIR IN THE CEILING
APPLICATION
INSTALLATION
RECOMMENDED
PRODUCTS
Mounting a PIR in the ceiling is an excellent way to hide wiring in single-level
homes. Running wires in an attic for ceiling mounted sensors allows you to easily
avoid water supply pipes, drain-waste-vent pipes, heating and cooling duct work,
venting duct work for kitchens and bathrooms, and high voltage wiring. It is also
useful for providing complete coverage of rooms with obstructions such as halfwalls
and shelving that can block coverage.
The Sentrol SureShot PIR and low profile Aritech PR361 provides 360° coverage
when mounted in the ceiling. For flush mount installation, install a standard
plastic single-gang outlet box. A remodel box can be used for homes where
construction is already complete.
Connect the wires to the terminal block of the sensor and screw the sensor and
cover plate into the box as you would an electrical outlet.
For ceiling mounting, drill a hole through the ceiling in the desired location and
pull the wire through. Punch out the wiring knockout in the back cover and pull
the wire through the hole. Attach the back cover to the ceiling using appropriate
mounting knockouts. Snap the circuit board and front cover into the back cover.
Walk-test the unit to ensure correct operation.
The 6255 SureShot, the 6255FM Flush Mount SureShot, and the PR361 can be
ceiling mounted.
SPACE DETECTION
Ceiling mount PIRs like the 6255 and PR361 help to eliminate obstacles in a room.
