Description

WattStopper®, WS250G, Wall Switch Occupancy Sensor, Series: WS Series, 120/277 VAC, 0 to 1200 W, 1/6 hp Power, Passive Infrared Sensor, 525 sq-ft Coverage, 180 deg Viewing, 30 s to 30 min Time Delay, LED Lamp, 60 Hz Response, Flying Lead Connection, Automatic On/Off/Manual Off Control Output, Strap Mounting, 35 deg C, Plastic, Gray, 2.6 in L x 1.7 in W x 1.55 in H Dimensions

PIR technology senses occupancy by detecting the difference between heat emitted from the human body in motion and the background space. Relying on a clear line-of sight view, passive infrared sensors make 100% coverage cut off possible. These sensors utilize a unique fresnel lens which divides the coverage area into zone, enhancing detection of small movement.

Features

  • Time delay adjustments - 5 to 30 min at minimum, 3 minimum if no activity after 30 sec at walk through mode, 5 sec for 10 min with DIP switch setting at test mode
  • Minimum to maximum sensitivity adjustment
  • 0 to 1000 VA tungsten, ballast, E-ballast, LED driver, 1/4 hp motor load requirement for each relay at 120 VAC, 0 to 1800 VA ballast, E-ballast, LED, load requirement for each relay at 277 VAC
  • Pulse count processing eliminates false Off without reducing sensitivity
  • Detection signature analysis eliminates false triggers and provides immunity to RFI and EMI
  • Zero crossing circuitry reduces stress on the relay and results in increased sensor life
  • Time delay adjustment from 30 sec up to 30 min
  • Adjustable unit sensitivity from 20% to 100%
  • Light level sensor holds lights off when ambient lighting is above the preset level
  • Custom 2-tier fresnel lens enhances detection at the desktop level
  • Sensor coverage tested to NEMA guide publication WD 7 to 2000
  • Patented voltage drop protection
  • For safety, there is no leakage to load in the Off mode and sensor is safety grounded
  • LED indicates occupancy detection
  • Compatible with decorator wallplates
  • Tungsten ballast E-ballast load type
  • Turns lighting on and off based on occupancy and ambient light level
  • It replaces existing wall switches and fits behind a standard decorator wallplate
