Ceiling mount sensors are offered in a multitude of configurations which address many applications. Lens options include large motion extended range, small motion standard range and bi-directional for hallways. Available in low voltage and line voltage models, these sensors are capable of covering an entire private office or small room by themselves. Multiple low voltage sensors can also work together to supply the ideal solution for oddly shaped rooms or large open office areas. A line voltage sensor provides one relay for a single level control, while the 2-pole version provides a second relay for an additional level of control. For rooms with obstructions, these sensors are also offered with dual technology, which adds Microphonics™ detection to the passive infrared (PIR) detection.
