1.2.2 The Z-Loop
This is a 2-wire loop, which provides power to devices, and communication between the
devices and the control panel. It is used for input and output devices such as sensors,
callpoints, I/O units, controllers, and loop-powered sounders. It operates on the proprietary
Ziton-ZP protocol.
All loop devices are individually addressed to provide the panel with unique identification of
each device. Up to 127 devices can be connected to each loop. Addresses may be located
on the loop in any desired order, and addressing is independent of the system-wiring layout.
Devices can be grouped into zones. These zones are software defined with no restrictions
on which devices may be grouped together, or on the loop to which they are connected.
The Z-Loop is protected from short-circuit and open-circuit, by means of loop-isolators.
These devices are inserted in the loop at specific points, usually between zones. In the
event of a loop short-circuit, or damage corrupts data transmission, the isolators on each
side of the fault disconnect that portion of cabling from the system. This ensures that a
maximum of one zone can be lost from a short-circuit or similar fault. Loop isolators do not
use a loop address.
The addressable Z-Loop can be wired as a class-A return loop, or as class-B single direction
with spurs. A loop with only low-power devices connected, such as sensors, callpoints,
interface-units, and controllers, can be up to 3000 metres in length. When high-power
devices, such as loop-powered sounders are attached, then the length of cabling will be
reduced. Refer to the Ziton ZP Wiring Guide before commencing system engineering or
installation.
