GENERAL
The line isolator is a bidirectional non-addressable loop monitoring device for addressable fire
detection system's loops. It is installed on the Addressable Loop, powered by the Loop and
monitors continuously the voltage levels and the signal's integrity. The main supported function
is to isolate a portion of the loop (between the two closer isolators) in the event of a short-
circuit. In case of two short circuit events, only the detectors before the first and after the
second short circuit are powered. Repair of the short circuit condition brings the loop condition
back to normal automatically (closed loop). Location of the short circuit position is achieved by
reading the lost address detectors attached on the top of each isolator. We can have up to 4
additional detectors-devices connected and controlled on a single isolator output (A and B
topology).
It is advised to apply up to 3 additional devices on the output of each isolator (4 detectors or 4
call points or 2 sirens). Maximum resistance between isolators in each loop, should not exceed
the 1,5Ohm. The consumption of the isolator must be considered in modification of existing
loops, to reduce by one the number of the detectors in full load loops. We can have up to 50
paired units (50 isolators + 50 detectors). For systems with more than 50 paired units, reduce
by one the detectors for every three added isolators.
The reasons that an isolator device is isolating are stated below.
