GCNET Network Overview
SYSTEM OPERATION
System Event Indication All Voice system faults are reported at the PMI/PMI-2/PMI-3, and at the programmed
speaker group control switch. The operator at the PMI/PMI-2/PMI-3 is able to ACK,
SILENCE/UNSILENCE, and RESET voice system events. For example, in the event of
an ALL EVAC, the Audibles LED on the PMI/PMI-2/PMI-3 comes on and the Silence
Audibles soft key displays on the PMI/PMI-2/PMI-3, so the system can be silenced
from the Global PMI/PMI-2/PMI-3.
FCC Trouble Sounder An “FCC Trouble Sounder” may be configured on the FCC. The Trouble Sounder
annunciates, via a Flashing Yellow LED, the existence of any trouble or fault with the
FCC with the FCC hardware, or of any functionality provided by the FCC. When it is
on, an audible sounder is repeated with a nine second Off and one second On cycle.
When active, the Trouble Sounder may be silenced by pressing the button. Once
pressed, the LED changes to Solid Yellow and the sounder is deactivated. Silencing
the Trouble Sounder does not Acknowledge the corresponding trouble events on the
event displays.
A silenced Trouble Sounder will be reactivated after 24 hours if trouble conditions
remain.
