The WV 16 Series Wide View occupancy sensor is designed to mount in a corner and detect small motions up to 40 ft (12.19 m) away, and larger motions up to 70 ft (21.34 m) away. This makes it ideal for 30 ft x 30 ft (9.14 m x 9.14 m) classrooms or corridors up to 70 ft (21.34 m) long. The enclosure’s convenient tilting feature enables the sensor to be mounted at any height from 8 to 10 ft (2.44 to 3.05 m). When corner or wall mounting is not possible, the WV BR bracket accessory can be used to mount the WV 16 to the ceiling. Additionally, the WV 16 may be used in combination with other sensors to customize coverage for very large or irregularly shaped spaces. For rooms with obstructions, use the WV PDT 16 Series sensor which adds Microphonics™ detection.FEATURES:• 100% Digital PIR Detection, Excellent RF Immunity• 120º by 40 ft (12.19 m) Coverage for Small Motion• Adjustable Time Delay• Push-Button Programmable• Convenient Test Mode• No Field Calibration or Sensitivity Adjustments Required• 100 hr Lamp Burn-in Time
