Abstract
A ground fault detection scheme uniquely incorporated within a distributed intelligence, fire alarm and detection system, such that detection is achieved with location identification. The modules (and transponders) of the system collaborate with the loop controller in performing ground fault operations to determine precise existing ground conditions at the module locations.
