Abstract
A fire detection system may include isolation circuit having an isolation switch coupled with a system line of the fire detection system and configured to isolate a first side of the system line from a second side of the system line. The isolation circuit may also include a controller coupled with the isolation switch. The controller may be configured to detect repetitive, intermittent short circuit activity on the system line and control the isolation switch based on this activity.
