Connecting to Remote Switches for Tone Activation

The 300VSC tones can be activated remotely by any normally open, low-current switch contacts with a
current capacity of at least 50 mA inductive. Figure 4 illustrates the connection of switch contacts to the
300VSC. The designations S1, S2, S3 and S4 represent remote switch contacts such as those found in flow
switches, program clocks, heat detectors, and smoke detectors. The remotely activated tone sounds as long as
the activating contacts remain closed.

Installing SelecTone Tone Modules

See Figure 4. The 300VSC can accommodate up to four SelecTone tone modules of your choice. To
install the tone modules, insert them into the desired receptacles on the printed circuit board. The
