LC-200S is an analog PIR detector with digital processing. Top drawer quality and detection efficiency of LC-200S 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-200S 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.
