The nCM 9 Series nLight® Standard Range 360 deg occupancy sensor offers amazing performance and sensitivity to small motions (e.g. hand movements). Ideal for small rooms with drop ceilings and areas without obstructions, the nCM 9 is a snap to install. Its light weight allows surface mounting to drop ceilings or a ceiling grid. The nCM 9 sensor can cover entire private offices or smaller rooms by itself; however it is also the ideal lead sensor for odd shaped rooms. For example an nCM 9 in a restroom vestibule can be paired with an nCM PDT 9 Dual Technology sensor in a main stall area. Another application is an nCM 9 controlling an entrance hall to a classroom and communicating with an nWV PDT 16 controlling the main room. In both cases the lights would be activated on by the nCM 9.
