Product Description

Wattstopper’s dt-200 series dual technology ceiling sensors combine pir and ultrasonic technologies into one unit to attain precise coverage in finding tenancy. Low voltage dt-200 series sensors make use of a Wattstopper power pack to turn lights on when both pir and ultrasonic technologies discover tenancy. They can likewise work with a low voltage switch for manual-on operation. Pir technology senses movement by means of a modification in infrared energy within the regulated location, whereas ultrasonic uses 40 kHz high frequency ultrasound. Once on, detection by either innovation holds lights on. When no occupancy is detected for the length of the time delay, lights shuts off. Dt-200 series sensors can also be set to activate lights on when either technology or both discover occupancy, or to require both innovations to hold lighting on. 24 vdc/VAC and half wave remedied A/C – 40 kHz frequency ultrasonic transmission – dead time: automobile set, repaired (5, 10, 15, 20 or 30 minutes), walk-through/test modes – level of sensitivity modification: vehicle set; reduced sensitivity (pir); variable with trim pot (ultrasonic) – integrated light level sensor: 2 to 200 foot-candles (21 to 2,152 lux) – low voltage, short-term switch input for manual operation – dt-200 includes an isolated relay with n/O and n/c outputs; rated for 1 amp at 24 vdc/VAC – 2000 Ft2 of walking movement mounted at 10 ft.; 1000 Ft2 of desktop motion – Max. Dt-200s per power pack: b=2, bz=3 Max. Dt-205s per power pack: b=3, bz=4 – dimensions: 4.4 inch x 3.4 inch x 2 inch (110.3 mm x 85.9 mm x 49.6 mm) L x W x D – UL and CUL noted – 5 year service warranty
