Occupancy Sensors

Leviton's Cat. No. ODS10-ID Decora 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 offices
• Conference rooms
• Lounges
• Class rooms

The ODS10-ID can be used for automatic switching of incandescent lamps and fluorescent and low-voltage lighting with electronic or magnetic ballasts. The unit also features 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 single-pole wall switch and fits in a standard wall box. The unit requires a ground connection.

Features and Benefits

• New, low-profile design eliminates obtrusive "scanning-device" look. Elegant Decora styling complements any interior; uses Decora wallplates and coordinates with Leviton's popular line of Decora wiring devices.
• 180° field-of-view provides approximately 2100 square feet of coverage suitable for small offices, conference rooms, class rooms, lounges and a variety of commercial areas.
• Convenient push-button provides manual ON/OFF light switching at any time.
• Segmented Fresnel lens provides optimum sensitivity and performance. Designed with an extensive "small motion" area where even slight body movements will be detected.
• Horizontal field of view may be adjusted between 180° and 32° of arc by using integral blinders located on either side of the lens.
• Optional manual adjustment for delayed-OFF time settings of 30 seconds (for walking test), 10 minutes, 20 minutes and 30 minutes. Allows customized adjustments to maximize energy savings.
• Adjustable Ambient Light Override ranges from approximately 2 foot-candles (2 lux) to 500+ foot-candles (500+ lux) to prevent lights from turning ON automatically during periods of ample natural light, increasing energy savings.
• Manual-ON/Automatic-OFF mode for installations where manual ON switching is required but automatic OFF switching is still desired for energy savings.
• LED indicator light flashes when sensor detects motion to verify detection is active.
• One unit can be used for either 120V or 277V lighting. Compatible with both electronic and magnetic ballasts.
• Relay switches at the zero crossing point of the AC power curve to ensure maximum contact life and compatibility with electronic ballasts.
• Fits in standard wall box and replaces single-pole wall switch. Gangable with other units.
• UL Listed and CSA Certified, complies with California Title 24 Energy Code and FCC regulations
• Limited Five-Year Warranty

The most advanced sensor available. Combines multi-technology with all-digital architecture. Eliminates false triggering. The result is a trouble-free, "install and forget" solution for lighting control.

Occupancy sensors have two tasks: keeping the lights on while the room is occupied and, conversely keeping the lights off when unoccupied. Ultrasonic (doppler shift) motion detection gives maximum sensitivity yet can be vulnerable to false triggering from air conditioning currents, corridor activity and movement of inanimate objects. Infrared motion sensing gives immunity to false triggering, but lacks sensitivity at greater distances. Leviton multi-technology sensors combine the benefits of both infrared and ultrasonic technologies for unrivaled performance and reliability.

Features

• Self-adjusting Settings: Callbacks for adjustment are eliminated. Time delay settings are continually adjusted.
• Non-Volatile Memory: Learned and adjusted settings saved in protected memory. Power outages will not cause status loss.
• Wide Coverage: Select the approximate area needed. Units from 500 to 2000 sq. ft. available.
• Ambient Light Recognition: The photocell prevents lights from turning on when the room is adequately lit by natural light
• Small Size: The spherical-section shape makes the installation almost invisible.
• Accurate, Consistent Switching: Occupant complaints are eliminated; lights are on when room is occupied, off when empty. Annoying false-offs are minimized and lights on at night is eliminated.
• Fast, Simple Installation: A single mounting post and three color-coded wires make installation easy.
• Photocell: 20-3,000 Lux adjustable. Factory set 3,000 L (photocell disable)
• Timer Settings: Automatic and Manual - 30s to 30 min. Test mode - 6 sec.

With ultrasonic and infrared sensing, this top-of-the-line sensor provides the highest degree of immunity to false tripping. Auto-Adapting circuitry fine-tunes delay settings for "install and forget" simplicity.

The OSW12-M Occupancy Sensor uses ultrasonic sensing for maximum motion sensitivity and infrared sensing for highest lights-off reliability. The sensor continually analyzes and adjusts to changing conditions.

The OSW12-M Occupancy Sensor uses the latest microprocessor-based technology which permits the detector to continually adjust and optimize its performance. The detector requires a 24 volt OSPxx Series power pack.

By combining ultrasonic and infrared technology, the OSW12-M Occupancy Sensor provides excellent small motion sensitivity (US) and error immunity (IR). The mounting base, provided with the sensor, allows quick and easy mounting in corners, on wall or on ceilings.

Features

• Multi-Technology: By using both infrared and ultrasonic signals, the sensor minimizes false reading for high reliability.
• Flexible Base Mounting: Supplied twist-and-lock base mount permits fast alignment. Supplied cover hides mounting hardware and wires. Can be used with raceways for hard surface installing. Wall or ceiling mount.
• Wide Coverage: Over 1200 sq. ft of coverage.
• Timer Settings: Automatic and Manual - 30s to 30 min. Test mode - 6 sec.
• Self-Adjusting: Internal microprocessor continually analyzes, evaluates and adjusts settings. Performance is kept at a maximum and user complaints are eliminated.
• Non-Volatile Memory: Learned and adjusted settings saved in protected memory are not lost during power outages.
• Ambient Light Recognition: A photocell prevents lights from turning on when the room is adequately lit by natural light. Both "occupied" and "low-light-level and occupied" lights-on control wires are supplied.

Provides low voltage power and line voltage control for Leviton Occupancy Sensors

Containing both a 24VDC supply and a 20A line voltage relay for most models, the Leviton compact power pack provides low voltage power and line voltage control for Leviton Occupancy Sensors. Versions include Auto-ON and Manual-ON inputs for occupancy sensors, Hold-ON and Hold-OFF capabilities, and a local input for momentary or maintained dry contact switches.

The internal relay can control up to 20A for a 120, 230, 277VAC or 347V ballast load and 20A for a 120VAC incandescent load. The OSP Power Pack Series is also used to supply power to the OSA Add-A-Relay model. The Power Pack conveniently mounts in a knockout hole of a standard junction box. The unit can be placed inside or outside the junction box with a simple twist-on nut.
