FIST MICROPHONE WITH
INTEGRAL PTT BUTTON
Select Button
Selects which zone(s) will receive the paging announcement from this microphone unit.
If pressed a second time, the zone will be de-selected.
Select buttons can be configured at the VAR DSP Router/System Control Unit to control a single
zone, a group of zones, all zones or to trigger recorded message playback.
Busy Indicator
When lit, indicates the zone (or one or more of the group of zones controlled by this button) is
already in use by another input. This microphone unit can only select the zone if the other input is
of a lower priority.
If a higher priority input selects the zone during a paging announcement, the zone will be
deselected and the Busy indicator will be lit. Announcements will continue to other zones.
Select Indicator
When flashing, it indicates the zone is successfully selected and is ready for use by this
microphone station. This indicator will be steady once the PTT button is pressed (as long as a
higher priority input has not selected the same zone).
If a higher priority input selects the zone during a paging announcement, the zone will be
deselected and the Select indicator will go out. Announcements will continue to other zones.
If configured for recorded message playback, flashing indicates that playback is finishing.
Press To Talk
Button
The press-to-talk button is integral to the fist-microphone. When pressed, it activates the all-call
zone selection, opens the microphone channel and triggers the pre-announcement chime (if
selected at the VAR DSP Router/System Controller) ready for the paging announcement.
When released, the microphone channel is closed and the zone selections may be either
cancelled or left selected as programmed at the VAR DSP Router/System Controller.
Speak-Now
Indicators
When the Press To Talk button is pressed, and the chime (if any) has finished, this indicator is lit to
indicate that the announcement can be made.
All-Call-Only
Indicators
Illuminates if there is a fault within the Router or FMS processor control or the RS485 comms
cabling between them. In this mode the microphone will work as all-Call when the PTT switch is
operated.
Status Indicator
Flashes green slowly to indicate healthy and powered status.
If the indicator flashes fast, there is an RS485 communications fault with the VAR Router.
If the indicator is off or on constantly, there is a fault with the FMS1 electronics or loss of power.
For full information about interfacing the FMS5-20 to the VAR Routers, refer to the DSP Router Handbook.
