The functions are in accordance with the technical details regarding the signalization circuits NFPA STYLE 6
%
NOTE: The maximum number of devices between two ISO-X is 25.
WORKING
To protect each device against the opening and the short-circuit (of all the other section) it is necessary to
separate each group of devices, connected on the SLC line, with a couple of ISO-X isolator of trouble
module.
For example, a trouble on the section 2 will not influence the sections 1 and 3.
The isolator module on both ends of the section 2 will cause the opening of the SLC line.
The section 1 will continue to operate by the supply from the canal “A”, the section 3 will continue through
the canal “B”.
Since the control panel will not be able to communicate with the devices of the SLC line of section 2, it will
be generate a trouble signalization (ANSWEAR NOT VALID from the Points of the section 2).
The circuit is a variation of the circuit regarding the STYLE 6 NFPA signalization line, so it is not possible a
“T” derivation or branchesfication of the circuit. The features are the same of the STYLE 6 CIRCUIT.
