VLC
General
The 69553 Volume Level Control (VLC) PCBA adds the capability of remotely controlling the local
speaker volume level. When VLC is activated, a remote device transmits a 50 kHz signal over the page
line. The station detects the 50 kHz signal and switches to an alternate speaker volume setting.
VLC and SmartSeries options cannot be used in the same station.
Features
 Provides an “alternate” speaker volume setting that is activated by receiving a 50 kHz signal on the
page line.
 Allows office or crew quarters speakers to be muted until a high priority message or alarm is
broadcast.
 Enables outdoor speaker volume to be reduced at night.
 Prevents local handset paging during emergency conditions.
 Adds the ability to provide a relay output (requires RTU option)
