Ziton ZP3 Serial control bus interface board

ZP3AB-SCB-R - Serial control bus interface

System control at remote locations The Ziton ZP3AB-SCB-R interface board provides a remote interface on the system control bus wiring enabling repeat indication and system control, at locations remote from the main panel position.

Usually installed within auxiliary equipment cabinets, the interface is compatible with all ZP3AB optional facility boards, including the RL8 relay module, the MIP8 input card and the OP24 open collector output card.

The interface can be positioned anywhere on the system bus wiring (which it shares with remote display units (RDUs). Driven from within the main control panel by an optional SCB-D driver board, a combination of up to 32 or 64 RDUs and SCB-Rs can be controlled dependant upon the ZP3 panel software.

RS485 protocol Serial communication between the main panel and the remote interface units operates by RS 485 protocol, over twisted screened pair wiring. Total cable length, (regardless of the number of remote units connected to a main panel), can be up to a maximum of 2 kilometres.

Installation flexibility Designed to provide installation flexibility, system wiring can be daisy chained or teed off with spurs. Wiring should be completed in data quality twisted screened pair cable with a minimum core diameter of 0.5 mm2. Jumper terminating switches are provided on both driver and interface, which are set at the system commissioning stage.

The Ziton ZP3AB-SCB-D and SCB-R serial control bus driver and interface are part of the range of optional facility boards which can be added cost effectively to any Ziton ZP3 fire system, in order to provide extra facilities, which may not be a requirement of every system.
