TORK occupancy sensors are a convenient way to turn lights on when individuals enter a room. Use the COS-M PIR Ceiling Mount Occupancy Sensor to cover a 1200 square foot area of office space, meeting rooms, bathrooms, storage facilities and more. When someone enters the sensor's area, the lights are automatically turned on and left on until no motion is detected for a specified time period from 5 to 30 minutes. For larger rooms, up to six TORK occupancy sensors may be joined. This sensor comes with a 5-year warranty and has an operational temperature range of 32 to 131 degree F. cULus-listed for 120/230/277V. For lighting installations you can count on, trust in the reliable name of TORK, a pioneer in the electrical industry since 1922.
