WS-301 and WS-301-347 models ending in -U are BAA and TAA compliant (Product produced in the U.S.)
WS-301
The WS-301 and WS-301-347 PIR Wall Switch Occupancy Sensors turn lighting or fan loads ON and OFF based on occupancy and
ambient light level. They are designed to replace a standard light switch. The WS-301 operates with 120 or 277VAC line voltage and the
WS-301-347 operates with 347VAC line voltage. All other features are the same in both models.
The sensor uses passive infrared technology to sense human motion, and defines it as
occupancy. A red LED on the sensor blinks upon occupancy and then resets. It will blink again
when it detects motion after the 2-second reset.
The sensor turns ON the load automatically when it detects occupancy. Once the space is
vacant and the time delay elapses, it turns OFF the load automatically.
If adequate ambient light is already present in the area, the sensor will hold OFF the load
it controls. When the light drops below a field selectable level and the sensor detects
occupancy, the sensor turns ON the load. Once turned ON, the load remains ON until the
space is vacant or the light level rises above the setpoint and the time delay expires.
Manual Operation
The occupant can press the ON/OFF button to turn the load ON and OFF. When the load
is turned ON manually, the sensor will keep the load ON until no motion is detected for the
length of the time delay. If the load is turned OFF manually, the sensor holds the load OFF
until no motion has been detected for the duration of 5 minutes. The next time the sensor
detects occupancy and the ambient light is lower than the set level, the sensor automatically
turns ON the load.
Manual/Auto mode
Manual ON
If you turn the light level trim-pot to the minimum position (fully counterclockwise), the WS-301 will enter Manual On mode. In this
mode, the occupant must press the ON/OFF button to turn ON the load. The sensor keeps the load ON until no motion is detected for
the selected time delay. There is a 30 second re-trigger delay. If occupancy is detected during the delay, the sensor turns the load back
ON. After the re-trigger delay elapses, the ON/OFF button must be pressed to turn ON the load.
Auto ON
If the light level trim-pot is not set to the minimum, the load will turn on and off automatically based on occupancy . When light level is
enabled, there is a 5 second re-trigger delay.
