12.3 LINE ELEMENTS INSTALLATION
Detection line wires and external signalling circuits wires are introduced to the control panel through
a round opening in the back side of the panel.
Before wire connection, it is necessary to examine thoroughly particular circuits routing to the
control panel output switch clamps. Special attention should be given to detection lines and loops
wires polarization.
Before detection lines wires connection, it is necessary to ensure whether the wires resistance and
capacity, and insulation resistance do not exceed allowable values.
Addressable detection lines elements connection way is illustrated in Fig. 12.3 and Fig. 12.4.
