Dual-Relay Multi-Technology Occupancy Sensor


The PIR is used to detect motion and turn lights ON, while either technology is used to keep lights ON while occupied. This allows the Ultrasonic (U/S) to be set to higher sensitivity levels minimizing false OFF conditions. The PIR portion gives immunity to false ON through a specialized lens that divides the field-of-view into sensor zones. When a person passes into or out of a sensor zone, the sensor detects motion and switches the primary lighting load ON while the secondary relay operates in manual-ON/auto-OFF. The lights will remain ON as long as there is an occupant moving through the sensor zones. The U/S sensors give maximum sensitivity and range in difficult spaces with irregular shaped rooms and partitions that can block the PIR field-of-view. Also features the ability to turn off PIR or U/S to become a single tech device.

Features & Specifications

• Provides automatic lighting control for two separate banks of fluorescent, incandescent, or low voltage lighting from a single unit.

• The second relay is a manual-ON only with a maximum 30 minute time-out for maximum energy savings to comply with CEC Title 20/24

• Fits in a standard single-gang wall box and replaces two single-pole wall-switches for fast and easy installation.

• Low-profile design eliminates obtrusive “scanning-device” look.

• 180° field-of-view provides approximately 2400 square feet of coverage, suitable for a variety of commercial areas.

• Convenient pushbuttons provide manual-ON/OFF light switching of each load at any time.

• Vandal resistant PIR segmented Fresnel lens provides optimum sensitivity and performance. Designed with an extensive “minor motion” area where even slight body movements will be detected.

• Patented 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 tape required.

• Manual-ON/auto-OFF mode for installations where manual-ON switching is required but auto OFF switching is still desired for CEC Title 20/24 energy savings.

• Time delay 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.

• Light sensor measures the ambient light in the room when it first detects motion and leaves the lights OFF (hold-off) if there is enough light in the room or turns the lights connected to the first relay ON if there is not enough light in the room.

• Self-Adaptive technology eliminates callbacks for adjustments. Time delay and sensitivity settings are continually adjusted to occupant patterns of use in auto adapt mode.

• Exclusive Walk-Through feature provides increased energy savings by not leaving the lights ON for an extended period after only momentary occupancy.

• Non-Adaptive Mode disables self-adjusting delayed-OFF time and walk-through feature in applications where these feature are not desired. Optional manual adjustment for delayed-OFF time settings allows customized adjustments to maximize energy savings.

• Vacancy confirmation; when the time out expires and the relay turns OFF, a 30-second vacancy confirmation exists to turn the relays back ON.

• Ability to disable PIR or U/S for added flexibility.

• Presentation Mode feature for slide or film presentations allows pushbuttons to turn lights OFF and keep them OFF while the room is occupied.

• Exclusive High Inrush Stability (H.I.S.) Circuitry. Specifically designed to handle today’s high inrush electronic ballast loads and offer unmatched durability and service.

• One unit can be used for 120V through 277V lighting. Compatible with both electronic and magnetic ballasts.

• 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.
