Pa/Fog Operation; Operating The Pa/Hailer Mode - Standard Horizon QUANTUM GX5500S Owner's Manual

8.11 PA/FOG OPERATION

The GX5500S has a 30W hailer built-in and can be used with any 4 Ohm
PA/Hailer horn. Standard Horizon offers two PA/Hailer horns, the 220SW (5"
round 30 Watt PA/Hailer horn) and the 240SW (5" x 8" rectangular 40 Watt
PA/Hailer horn). When the GX5500S is in PA/HAILER mode the PA/Hailer
horn listens back (acts as a microphone and provides two-way communica-
tions through the PA/Hailer horn to the main radio).
When in the PA/HAILER or FOG HORN mode, the GX5500S will
continue to receive DSC calls and communications on the last select-
ed working channel prior to entering the PA/HAILER or FOG HORN
mode.
PA/HAILER mode:
This mode allows the transceiver to be used as a powerful loud hailer
when an optional STANDARD HORIZON 220SW or 240SW PA/Hailer
horn is installed. The PA/HAILER mode has a listen-back feature which
provides two way communication through the PA/Hailer horn.
FOG HORN mode:
Automatic signaling is transmitted through the PA/Hailer horn. When
the fog horn, bells or whistle signal is not being outputted the GX5500S
listens back through the connected PA/Hailer horn.
