Whether it’s a residential or commercial installation, the LC series of detection devices readies a security system for the unexpected by providing protection for every room, corner and corridor. The LC-103-PIMSK, LC-104-PIMW and LC-124-PIMW are dual-technology motion detectors that combine passive infrared and microwave detection with pet immunity. The LC-103-PIMSK also has support for anti-masking. The anti-masking feature prevents intruders from defeating the detector by covering its field of view.
