Installation and Maintenance Manual

Connecting a Low-Level Audio Output

See Figure 6. The 300SCW-1 also has a 1 Vpp audio output that can be coupled to the audio input of
another amplifier. This low-level output is available across terminals TB1-1 and TB1-3. It can also be
connected to an analog fiber optic transmitter so that audio can be transmitted over a fiber optic link in
an electrically noisy environment.

Connecting to Remote Switches for Tone Activation

The 300SCW-1 tones can be activated remotely by any normally open, low-current switch contacts with
a current capacity of at least 50 mA inductive. Figure 7 illustrates the connection of switch contacts to the
300SCW-1. 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.
