Replacement Delay Switches fitted to circuit shown in fig. 5
A DS1 and two DSS’s can be used to replace these switches for both
wiring systems to give time delayed momentary switching at all
three switch locations. The DS1 should not be located at a former
intermediate switch location. The circuits for both wiring systems
with the replacement switches are shown in figs 6 and 7. No wiring
alterations are required but to establish which wires are connected
to which terminals the wires must be identified and traced. An in-line
connector is required for the Strapping Cable System to provide
continuity for the SL connection.
In keeping with BS schematic code wires shown in direct cross over
(i.e. +) are not connected electrically.
