10.3 Special functions
Line separator
Upon short circuit the part of the line that malfunctions must be separated from the
rest of the line. This is carried out by line separators integrated in each detector,
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”.
