The SILENT-KNIGHT-SK-ISO is an addressable line isolator module for use with Silent Knight IntelliKnight series fire alarm control panels (FACPs).

The SK-ISO is an intelligent fault isolator module that enables part of a communication loop to continue operating when a short circuit occurs on it. If a short occurs between any two isolators, then both isolators immediately switch to an open circuit state and isolate the device between them.
