Line separator
Upon short circuit the part of the line which malfunctions must be separated from
the rest of the line. This is carried out by line separators integrated in the detectors,
manual call points and input/output modules (however, there are detectors without
integrated separator).
A line separator is always integrated in the manual call points and input/output mo-
dules.
According to EN54 a "simple error" can cause the malfunction of up to 32 detectors
(i.e. install a line separator at least after every 32 detectors).
