CT-CL is
a complete enclosure cover for the APD-200, APMD-250, MPD-310, SLIM-PIR-LUNA, SLIM-PIR-PRO, SLIM-DUAL-LUNA and SLIM-DUAL-PRO motion
detectors. The Fresnel lens used in CT-CL changes their
character so that they can work as curtain detectors.
Replacement of the standard cover on CT-CL is very easy
and fast. The entire element is replaced without having to dismantle individual
parts.
