Manual ON multi-tech wall box vacancy sensor w/neutral wire lighting control, 120/208/220/230/240/277v, 50/60Hz, CEC Title 20/24 Compliant, 30s-30m Time Delays, Ambient Light Override, Self Adjusting, Field Configurable, Ivory, USMCA Compliant.Vacancy sensors have two tasks: keeping the lights ON while the space is occupied and turning the lights OFF when unoccupied. Leviton.s OSSMT Multi-Technology Decora Wall Switch Vacancy Sensor is used to provide automatic lighting control for energy savings and convenience in a variety of commercial applications. A wallbox vacancy sensor switch is a lighting control also known as a motion sensor or motion detector, part number OSSMT-TMI. Fast, simple Installation: fits in a standard wall box and replaces a single-pole wall-switch; neutral and no neutral options available. Sensor can be ganged together with other units in a multiple-switch wall plateLow-profile design eliminates obtrusive .scanningdevice. look. Elegant Decora wallplates complement any interior for sleek aesthetics; uses Decora wallplates and coordinates with Leviton.s popular line of Decora wiring devices.Convenient push button provides manual-ON/OFF light switching at any timeSegmented Fresnel lens provides optimum sensitivity and performance. Designed with an extensive .minor motion. area where even slight body movements will be detected.Vandal-resistant PIR lensBlinders: adjustable horizontal field-of-view (PIR may be adjusted between 180. and 60. of arc by using integral blinders located on either side of the lens). No masking required.Manual-ON/auto-OFF vacancy sensor for installations where manual-ON switching is required but auto-OFF switching is still desiredLED indicator light flashes when sensor detects motion to verify detection is active. Green flashes for ultrasonic, red flashes for PIR.Time: the delayed OFF time is preset at 30 minutes in the auto adapting mode. A choice of four delayed-OFF time settings are available: 30-seconds (for walking test purposes only), 10, 20 and 30 minutes for fixed time and auto adapting.Self-adaptive technology: callbacks for adjustment are eliminated. Time delay and sensitivity settings are continually adjusted to occupant patterns of use in auto adapt mode.Vacancy confirmation: when the time out expires and the relays turn OFF, a 30 second vacancy confirmation exists to turn the relays back on False detection circuitrySmall motion sensitivity (U/S): ultrasonic technology provides excellent minor motion sensitivityAbility to disable U/S (OSSMT-TM). For added flexibility, OSSMT-GT has the ability to disable PIR or U/SExclusive Leviton circuitry.
