SHORT CIRCUIT ISOLATOR 6202L
1. INTRODUCTION
Short circuit isolator 6202L is designed to cut off (to isolate) a short circuited segment in a line
(loop). In this way the variable units ñ automatic fire detectors, manual call points and others, which
are not in the short circuited segment remain active and the line (loop) protection level is higher.
Where isolators are not included, in case of a short circuit the fire control panel interrupts the power
supply of the line (loop) and all units stop working.
A segment is a part of a loop between two adjacent isolators.
