TION WRITER’S GUIDE
Furnish and install where indicated a passive infrared occupancy sensor
capable of (Model PC10A) covering an area of up to 1000 square feet or .
. .
(Model PC10H) for aisles, corridors, hallways with a detection range of 80
feet long x 16 feet wide . . . or (Model PC20A) covering an area of up of
2000 sq. ft. Sensor shall be equipped with a separate adjustment for
delayed time off of 30 seconds to 15 minutes. Sensor shall be designed for
mounting onto a ceiling.
Sensor is to be supplied with a transformer relay power pack which can be
installed remote from sensor using low voltage wire. (Powerpack can be
installed close to load in order to minimize line voltage wiring). The remote
powerpack shall be capable of installation in a single or multiple gang box.
One remote powerpack shall be capable of operating a maximum of four
sensors. Sensor and transformer relay powerpack shall be TORK Models
PC10A/PC10H/PC20A and TRP respectively.
