Typical Wiring Connection
Fig.1
Fig.3
Fig.2
Fig.1 Using End of Line resistor, in compliance with
EN/BS standard, when using EOL resistor, call points
should be wired before detectors, so that the removal of
any detector will not inhibit call point from operating.
Fig.2 Using Active End of Line, enables call points to be
installed in any location on zone as will not affected by
removal of detector (required base DZ-03D)
Fig.3 The same as fig.2 principle, using AEOL without
detector.
