Line voltage wide-view and hallway occupancy sensors provide fully self-contained lighting control solutions for wall, corner, or ceiling mounting. These sensors are designed to simplify installation for contractors while delivering a secure, polished finished appearance. Adjustable angled brackets and multi-position chase nipples allow precise alignment during setup, minimizing installation time and ensuring professional results. Utilizing advanced passive infrared (PIR) technology and digital signal processing, these sensors achieve highly accurate motion detection. Certain models include an integrated microphone that enables passive acoustic occupancy detection, providing overlapping coverage in spaces where obstructions or limited occupant movement may reduce PIR effectiveness. Optional features further enhance control, including ambient light sensing that automatically turns lights off when sufficient daylight is present.
Each sensor operates by detecting infrared energy emitted by occupants as they move within its field of view. Upon detection, an internal relay activates the connected lighting. In dual-technology models, acoustic detection activates alongside PIR once occupancy is detected, providing extended coverage in challenging environments. Lights remain on during brief periods of inactivity through an internal timer, which resets whenever motion or sound is detected. Optional daylight sensing functionality further enhances energy efficiency by preventing lights from operating in adequately illuminated spaces.
These line voltage sensors are self-contained units that directly operate on 120/277 VAC. They are ideal for areas where a single sensor can cover an entire space, such as classrooms, open areas, large offices, conference rooms, and hallways. For longer corridors or larger areas, multiple sensors can be parallel-wired to extend coverage. Wide-view models provide a 120° field of detection, capturing both small motions, such as hand movements, and large motions, such as walking, within a typical range of 40 to 70 feet depending on mounting height. Hallway models offer long-range detection up to 100 feet, with optimal sensitivity when occupants cross the coverage beams perpendicularly.
Dual-technology units integrate PIR and acoustic detection to ensure reliable occupancy sensing in spaces with intermittent motion. Initial occupancy detection through PIR triggers acoustic functionality, while sounds associated with occupant presence reset the time delay. Non-occupant noises are filtered, and acoustic signals alone cannot sustain lighting indefinitely; periodic PIR detection is required for continued operation. Following sensor timeout, acoustic detection remains active for 10 seconds to allow voice reactivation of lighting, enhancing convenience and safety.
Sensors are compact and feature a matte finish for unobtrusive integration into interior spaces. Physical dimensions are 2.875 inches in height, 2.75 inches in width, and 3.25 inches in depth, with a weight of 4.75 ounces. Units are available in white and are compliant with RoHS standards. They operate within a temperature range of 32°F to 122°F (0°C to 50°C) and relative humidity up to 95% non-condensing for indoor use.
Electrical specifications include multi-voltage operation on 120/277 VAC single-phase circuits, with load ratings of 800W at 120 VAC and 1200W at 277 VAC. Compatible load types include tungsten, electronic and magnetic ballasts, and LED fixtures. Timed switching is electronically controlled for extended relay life, with adjustable delays ranging from 30 seconds to 30 minutes, and a default setting of 10 minutes. Test mode enables quick verification of coverage, with a five-second cycle for on-site adjustments.
Wide-view 120° PIR models are designed for mounting heights of 8 to 12 feet, offering small motion detection up to 40 feet and large motion detection up to 70 feet. Hallway long-range PIR models maintain the same recommended mounting height but provide large motion detection up to 100 feet, with optimal sensitivity for cross-beam entry. Sensors equipped with integrated photocells offer ambient light override operation, turning lights on or off based on detected daylight levels. This capability is particularly useful for locations near skylights or windows, enhancing energy efficiency without sacrificing occupant comfort.
Overall, these line voltage wide-view and hallway occupancy sensors combine advanced PIR and optional acoustic detection, versatile mounting options, daylight harvesting, and robust electronic timing to deliver reliable, energy-efficient lighting control for commercial and institutional spaces.
