10 CONTROL PANEL NETWORK OPERATION
The POLON 4000 system control panels may be connected with one another by means of a double pair
of wires (or a pair of optical fibre cables) in a form of a ring in order to create a network of control
panels. The double ring of connections among control panels prevents from the network system fault in
case any transmission path is faulty (redundancy).
Up to 31 control panels equipped with the MSI-48 module may operate in a network. All units should be
equipped with identical software versions. Each control panel should have an individually programmed
number from the 1 ÷31 range (local control panel number) and the numbers must not repeat. A control
panel number is declared within software and additionally set within hardware on the MSI-48 module
keys. The compliance between the declaration and hardware setting is checked. The number set within
hardware is used by the MSI-48 module in case the I2C connectivity with the PSC-46 module is
interrupted. A standalone control panel (outside the network) must be programmed as No. 0 (the MSI-
48 must be disconnected and not declared). The network should include a control panel programmed
with no. 1 – MASTER. The MASTER control panel makes it possible to program the system configuration,
i.e. the set of numbers of control panels belonging to the network elements, i.e. SLAVE control panels.
The MASTER panel transmits the system configuration to the SLAVE panels and monitors the network. In
the event of the MASTER control panel fault, the next control panel in the sequence takes its role over.
Every network control panel makes it possible to declare a group of control panels which co-operate
with it in order to create this control panel common detection zone. The network control panel, in which
other (remote) panels are declared for co-operation, works as a collective control panel.
This function is not symmetrical, i.e. if control panel B is within the common detection area of control
panel A, control panel A is not required to be included in the common detection area of control panel B.
In particular, this function allows creating zones in which the differentiated control panel enables to
collect fire and fault signals from several control panels without reciprocity or with full reciprocity. The
network logical configuration diagram is shown in Fig. 10.1.
In special cases, the collective control panel may serve as a local control panel if no remote panel has
been declared to co-operate with it.
