GWACC
Audio Command Center
Voice Evacuation Control Panel
Description
Gamewell’s
Audio Command Center
(GWACC)
is a state-of-the-art, single-
or dual-circuit (25 watts each) Emer-
gency Voice Evacuation Control Panel
(EVAC). It is expandable to 50 watts.
The GWACC provides the ability to
record five field-programmable mes-
sages (up to 60 seconds total mes-
sage duration) with an integral com-
mercial-grade emergency communica-
tions microphone or from an external
audio source. Significant technological
enhancements set the GWACC apart
from other EVAC panels — these in-
clude full supervision in both active
(alarm or music) and standby condi-
tions, supervision of amplifier outputs,
field wiring, message generator, all tone
generators, and the microphone. The
integral power supply is capable of
charging up to 18 AH batteries, which
can be housed in the GWACC
Standard Features
•
Integral 25 watt, 25 V
RMS
audio amplifier with
single Style Z (Class A) or Style Y (Class B)
speaker circuit (expandable to 50 watts using
the
ACC-AAM25).
• Modular design for max.system flexibility.
• Five Command Input Circuits (CMD) are
available for activation by an FACP.
• Two command input circuits can be field-
programmed for activation by a Notification
Appliance Circuit (NAC) or contact closure.
• Three command input circuits activate on
contact closure.
• Manual deactivation of speaker zones.
•
Command inputs allow:
– One 60-second message.
– Two 30-second messages.
– Three 20-second messages.
– Four 15-second messages.
– Five 12-second messages.
• Microphone time-out feature.
• Nineteen different system & diagnostic LEDs.
• Two Form-C trouble relays (System & AC
Power Loss).
•
Optional equipment:
second amplifier; local
playback speaker; and remote microphone.
• Integral digital message generator with
standard, factory-prerecorded emergency
evacuation message.
• Custom messages are field recordable,
without the addition of add-on modules, using
the integral microphone or audio input jack.
• Digital message may be field-selected for 3,
4, 6, 8, or infinite repeat.
• Built-in alert tone generators with steady, slow
whoop, high/low, or chime tone capability.
• Field-selectable lead-in/trailing tone selection.
• Alert tone selection may be field-programmed
to conform with ANSI S3.41 Audible
Emergency Evacuation Signal (Temporal
Pattern), per NFPA.
• Speaker zone control via CMD inputs/
keypad.
• Dual-optically-isolated, trigger input circuits
are independently field-programmable for
activation by polarity reversal (host FACP
NAC) or dry-contact closure.
• Zone 1 switch-programmable for All-Call
operation.
• Integral diagnostic LEDs include: Power,
System Trouble, Microphone Trouble,
Message Generator Trouble, Tone Generator
Trouble, Amplifier Fault, and others.
• Independent Form-C trouble relay allows
FACP to monitor voice system while in
active (alarm) state.
• Integral piezo provides local audible indication
for troubles. All outputs are power-limited.
• Fully supervised in
Standby
and
Active
states, including integral microphone, amplifier
output, message generator, speaker wiring,
and tone generators.
• Independent amplifier supervision: current
limit, audio level, short circuit protection.
• Auxiliary power output provides local power
for addressable control modules when used
to activate the GWACC.
• Compatible with all Gamewell FACPs, as
well as other manufacturers’ panels.
• Background music capability (requires AHJ
approval) with total output power per amplifier
reduced to 20 watts.

The GWACC is suitable for use as an adjunct (slave or stand-alone) to most UL-
Listed Fire Alarm Control Panels (FACPs). An optional 25 watt, 25 V
RMS
audio
amplifier is available for system expansion to 50 watts (providing dual 25-watt
speaker circuits) or as a secondary amplifier in jurisdictions requiring such
backup. A 70.7 V
RMS
converter is also available for independently converting
amplifiers to meet retrofit needs.
A host of field-programming options, including the capability of five custom mes-
sages (fire, tornado, evacuation, hazmat, non-fire, multi-language, etc.) make
the GWACC the most versatile voice evacuation system available. Some suit-
able applications for the GWACC include schools, auditoriums, dormitories,
theatres, restaurants, places of worship, lodging, office buildings, and factories.
