25.3 Special functions
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 each detec-
tor, manual call point and input/output module. According to EN54, a ”simple error”
may not cause the malfunction of more than 32 detectors. After the short circuit the
line automatically reverts to ”Normal operating condition”.
