The CM is a low voltage sensor that easily mounts directly to a ceiling tile or a metallic grid. 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. Multiple low voltage sensors can work together to supply the ideal solution for oddly shaped rooms or large open office areas. For rooms with obstructions, these sensors are also offered with Dual Technology, which adds Microphonics™ detection to the Passive Infrared (PIR) detection.
