• Photo sensor for natual daylight control (some models)
• Vacancy sensors permanently configured for Manual-ON/Auto-OFF
Operation
CENTO 120/277Vac sensors draw control power directly from the lighting circuit they are intended to control.
When in operation the sensor will detect initial motion using Passive Infrared (PIR); once motion is detected, the
internal contact will close. Motion through PIR is used to maintain the occupied condition as long as occupants
remain within coverage range and line-of-sight of Sensor.

Wiring Diagrams
CENTO 120/277Vac sensors include #14 AWG wiring leads. Use appropriate sized wire nuts for connecting
wires.
CAUTION: Turn power off at the circuit breaker before working on sensor. According to NEC 240-83(d), if the
branch circuit breaker is used as the main switch for a fluorescent lighting circuit, the circuit breaker should be
marked SWD. All installations should be in compliance with National Electric Code (NEC) and all state, provin-
cial, federal, and local codes.

Sensor Location Guidelines
To optimize the performance of CENTO Sensors, please review the coverage pattern, range, and model
to match with the application. Room dynamics will change when people and furniture are occupying the
space. In some rooms, after move in, some sensors may require adjustments.
• Ensure that the sensor is at least 30 inches away from air handlers/registers and not pointed directly at
windows
