The Leviton Smart 24 Volt dimming wallbox sensor (ODD24-IDW) is designed for use with an OPP20 or OSA20 power pack or other Leviton (24 Volt) low voltage sources. Lighting levels can be adjusted using the dimming bar next to the switch and uses passive infrared (PIR) detection technology to monitor a room for occupancy using a segmented, tamper-resistant lens. When a person passes in or out of a sensor zone the sensor detects motion and switches the lights ON. The lights will remain ON as long as long as an occupant moves through the sensor zones and after the timeout expires. The ODD24-IDW features a vacancy mode for manual ON/auto OFF operation, ideal for installations where manual ON switching is required for energy code applications. A minor motion zone detects small body movements. This detection allows the lights to remain ON when individuals in the space are more stationary. The major motion zone exhibits a lesser degree of sensitivity requiring larger movements.
