About the Crestron GLA-IR-WLS-1
Crestron notes that PIR is used where the sensor will have a clear view of the occupants in the coverage area. The sensor controls line voltage lighting at 120/230/277 VAC, 50/60 Hz through a single relay, has a 180° coverage pattern, and offers a choice of manual ON or automatic ON. IQ Mode adjusts the ON time delay by learning how the room is used.
A walk through mode can switch the load OFF after 3 minutes if nothing more is detected after the first 30 seconds, and an audible alert warns that the load will shut OFF in 10 seconds unless further motion is detected. Switch Link communication lets up to 4 sensors be grouped together, and the light level feature keeps the lights OFF when there is sufficient daylight.
It mounts in a single-gang NEMA-style standard switch box, with a decorator-style wall plate by others. Typical applications are small offices, conference rooms, storage closets and break rooms, and Crestron advises enclosed spaces no larger than 18 ft x 15 ft. This page covers the white version, GLA-IR-WLS-1-W.
