Vacancy Sensor, Multi-Technology (PIR Sensor / Ultrasonic Sensor), Wall Switch, 2400SF, 120-277V, No Neutral, Ivory, Self-Adaptive, Decora¨

• 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 plate
• Low-profile design eliminates obtrusive ÒscanningdeviceÓ look. Elegant Decora wallplates complement any interior for sleek aesthetics; uses Decora wallplates and coordinates with LevitonÕs popular line of Decora wiring devices.
• Convenient push button provides manual-ON/OFF light switching at any time
• Segmented Fresnel lens provides optimum sensitivity and performance. Designed with an extensive Òminor motionÓ area where even slight body movements will be detected.
• Vandal-resistant PIR lens
• Blinders: 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 desired
• LED 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 circuitry
• Small motion sensitivity (U/S): ultrasonic technology provides excellent minor motion sensitivity
• Ability to disable U/S (OSSMT-TM). For added flexibility, OSSMT-GT has the ability to disable PIR or U/S
• Exclusive Leviton circuitry. Specifically designed to handle todayÕs high inrush electronic ballast loads and offer unmatched durability and service
• True zero-cross relay switches at the zero crossing point of the AC power curve to ensure maximum contactor life and compatibility with electronic ballasts
• Non-volatile memory: after power loss, product returns to last state
