1.2.4 The SCB (External) Control Bus
The Serial Control Bus (SCB) is used to connect the panel to external peripheral devices
such as remote display units, remote I/O boards, mimic panels, and similar devices. The
SCB-bus is the external equivalent of the internal ICB-bus described on the previous page.
Remote display units are intelligent repeater panels, which may be installed at various
locations to provide local indication and control functions. They are available in "mini"
versions which provide LED-indication, text-display, and basic operator functions, and in full-
function models which also permit full menu access, maintenance and diagnostic functions,
and system set-up.
Remote control units are I/O control panels that house switched inputs and outputs used
for controlling devices such as sounders and led's, and for interfacing to other building
systems. Outputs are either voltage-free contacts, or switched DC voltage. Each input or
output point is addressable, and can be programmed to operate as required.
Remote mimic panels are LED-based zonal indicator panels.
The ZP3 panel incorporates one control-bus, with 1024 addresses, which can be either
inputs or outputs. Refer to the address list for details. These addresses are in 2 groups.
1 SystemBus (Group 09) Addresses 000 - 255 Controls panel functions,
including zones, common
LEDs, and control keys. Can
be used for external mimic
functions.
2 UserBus (Group 10) Addresses 000 - 768 Freely programmable.
The SCB-bus can be either a 2-core shielded copper-wire RS485 connection (2 Km), or a
fibre-optic connection (30 Km). Devices connected to the SCB-bus require 24 volts DC.
