Line splitter for Cerban communications CBS-3
The Cerban Splitter CBS-3 is used to duplicate a
Cerban communication line. A Cerberus control panel,
such as a CZ10, a CZ12 or a CS4, transmits data
using the Cerban protocol and for each control panel
only one line is available. If you need to transmit the
messages coming from the control panel to two
different supervising systems, or if you want to be able
to send commands to it from two different supervising
systems, you need the CSB-3.The CBS-3 is an
intelligent device that routes properly the messages,
avoids conflict and monitors the line status. In a typical
application, the CBS-3 is connected to a CZxx
downward and to a Gateway GW-00 or GW-01 upward,
to be connected to an LMS. The other line available on
CBS-3 can be sent to any other device, for instance to
an other supervising system, to a redundant LMS or to
a supervising system on WAN (Wide Area Network).
Features
§ CBS-3 is composed by two Europe-format boards
connected in a piggy back configuration. The CPU
board contains the microprocessor and the
firmware to manage the device operations and the
asynchronous board manages the communication
lines
§ Three communication lines are available: two to
connect supervising systems, one to connect a
control panel which communicates using Cerban
protocol
§ Five front LEDs on the CPU board show the CBS-3
status
§ The front LEDs on the asynchronous
communication board display the line status
