Decora Wall Switch Occupancy Sensor APPLICATION Leviton's Cat. No. ODS] OLD Decors Wall Switch Passive Infrared (PIR) Occupancy Sensor is used to provide automatic lighting control for energy savings and convenience in a variety of commercial applications, including'. Small office • Conference rooms Lounge Class rooms The ODS] OLD can be used for automatic switching of incandescent lamps and fluorescent and low voltage lighting with electronic or magnetic ballasts The unit also feature a manual override switch that can be used to keep lights OFF while an area is occupied, which may be desired in conference rooms and other areas during slide or film presentations. The unit installs in place of a singlepole wall switch and fits in a standard wall box The unit requires a ground connection. OPERATION The ODS] OLD uses passive infrared (PIR) detection technology to monitor a room for occupancy through a segmented Fresnel lens. This specialized lens divides the field of view into sensor zone. When a person passes into or out of a sensor zone, the sensor detects motion and switches the lights ON. The lights will remain ON as long as there is an occupant moving through the sensorzones A delayed -OFF time adjustment prevents the lights from switching OFF when the space is occupied. In order to keep the lights ON, a person must pass through a sensor zone at least once during the selected delayed -OFF time interval. An LED indicator blinks each time the unit detects activity in the sensor zone. When the space being monitored by the sensor is unoccupied for the length of time chosen as the delayed -OFF interval, the unit will switch the lights OFF To ensure longer service life and compatibility with electronic ballasts, the device carefully times its switching contact opening and dosing with the zero crossing point of the AC power curve. This minimizes contact wear caused by inrush currents from electronic ballasts Push-button Manual Override Control For manual control, the ODA OLD features a convenient push- button ushbutton switch. If the lights are OFF, pressing the button will tum lights ON and keep them ON for as long as the room is occupied. The lights will be turned OFF once the room is vacant, after the delayed-0FF time expires If the lights are ON, pressing the button will tum lights OFF and keep them OFF even if the Mil SPECIFICATION SUBMITTAL JOB NAME 777M7RS JOB NUMBER. Cat. No. OD510-I11) ODS10-ID I room is occupied. This feature is particularly useful for media presentations. The lights can be turned back ON by simply pressing the button. The unit will then return to normal operation. If the button is not pressed to tum the lights back ON and the unit doe not detect any motion duringthe delayed - OFF time interval, the light will remain OFF The unit then returns to normal operation where the lights will remain OFF until it detects occupancy and automatically switches lights ON. Manual-ON/Auto-OFF Mode In this mode, the unit will not tum lights ON automatically when motion is detectedlights can only be turned ON by manually pressing the pushbutton. The lights will remain ON as long as the unit detects activity in the sensor zone. The ODA OLD will shut lights OFF automatically after the space becomes unoccupied and the delayed-OFFtime expire. Lights can also be turned OFF manually at any time by pressing the push- button ushbutton. This mode is ideal for areas where manual ON switching is required but automatic OFF switching is desired for energy savings. 03 M Leviton Mfg. Co., Inc. Mmn. P.O.
