draws and minimum line voltages see the applicable datasheets. Refer to Ziton if
further assistance is required.
The Z-Address line must meet two criteria; resistance and capacitance. The
maximum permissible resistance of a loop is 75
ȍ
. This is the combined
resistance of both conductors. The total capacitance of a line should not exceed
0.7 µF with either leg shorted to earth.
Table 38 below gives the conductor sizes required for different loop lengths,
which meet the above criteria when using normal copper screened cable and no
loop powered sounders. Lengths for high capacitance cables should be reduced
accordingly.
Refer to Table 38 below.

Serial communication lines are data lines used to convey digital communication
between control panels and other devices, as well as between control panels in
multiple-panel network systems. Other devices include devices such as graphics
computers, remote display units, mimic panels, printers, accessory panels, and
so on.
Two types of serial communication ports are used on ZP panels, i.e. RS-232 and
RS-485.
RS-232 ports are used for connection to graphics computers, building
management systems and Ziton accessories, and for interfacing to building
