LC-203 is a fully digital PIR detector. It was designed to deliver unprecedented detection accuracy compared to traditional detectors with analog PIR and digital processing. Top drawer quality and detection efficiency of LC-203 is achieved thanks to lenses designed using LODIFF technology and made from POLY IR materials. In order to shorten the time of installation and simplify the process, the LC-203 features built-in EOL resistors with values required by PowerSeries Neo and PRO control panels. Installers may choose to use their own resistors for compatibility with any other hardwired control panel. The overall security of the installed system is further enhanced with double tamper protection (case opening and tearing from the wall).
