GWACC
Audio Command Center Voice Evacuation Control Panel Description
Gamewell's Audio Command Center (GWACC) is a state-of-the-art, singleor dual-circuit (25 watts each) Emergency Voice Evacuation Control Panel (EVAC). It is expandable to 50 watts. The GWACC provides the ability to record five field-programmable messages (up to 60 seconds total message duration) with an integral commercial-grade emergency communications microphone or from an external audio source. Significant technological enhancements set the GWACC apart from other EVAC panels -- these include full supervision in both active (alarm or music) and standby conditions, 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

cabinet. The GWACC is suitable for use as an adjunct (slave or stand-alone) to most ULListed Fire Alarm Control Panels (FACPs). An optional 25 watt, 25 VRMS 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 VRMS converter is also available for independently converting amplifiers to meet retrofit needs. A host of field-programming options, including the capability of five custom messages (fire, tornado, evacuation, hazmat, non-fire, multi-language, etc.) make the GWACC the most versatile voice evacuation system available. Some suitable applications for the GWACC include schools, auditoriums, dormitories, theatres, restaurants, places of worship, lodging, office buildings, and factories.

Application Examples
The GWACC is a voice evacuation control panel which can be used, with a variety of FACPs, to provide emergency audio messages. Two typical application examples follow.
One Speaker Circuit
Single output zone, single input circuit (see Figure 1). A very basic application consists of one GWACC with one amplifier and a single speaker circuit. This configuration is suitable for small facilities requiring no more than 25 watts of output power. A single fire evacuation message will be generated during an alarm condition from the host FACP, or can be manually generated with a message push-button. In this application example, the NAC from the host FACP is connected to CMD1. The CMD1 "out" terminals are then terminated with an end-of-line resistor for the FACP's Style Y NAC, or the terminals are wired back to the host FACP for a Style Z NAC. S3 DIP switches "1", "2", and "3" are set to OFF; this selection sends a 60-second message to the speaker circuit when the CMD1 input is activated. The S5 DIP switch "5" is set to OFF; this selection activates the CMD1 input by a reverse-polarity condition. CMD3, CMD4, and CMD5 inputs require end-of-line resistors. In this application example, the system may also be manually activated from the keypad. Press the Building Speakers push-button, then press the Fire Message push-button. Alternately, use the microphone to make an announcement.

Two Speaker Circuits
Dual output zone, dual input circuit -- tone/voice message (see Figure 2). This application example consists of one GWACC with two speaker circuits and requires the installation of a second amplifier. This configuration is suitable for small facilities requiring no more than 50 watts of output power and a 60-second fire evacuation message. In this application example, the addressable FACP directs tone or voice messages to either of the speaker circuits via the control modules connected to the CMD1 and CMD2 inputs. S3 DIP switches "1", "2", and "3" are set to OFF; this selection configures CMD1/CMD2 to direct the Fire Message to the Auditorium Speakers or Classroom Speakers. The S5 DIP switches "5" and "6" are set to ON; these contact closures activate CMD1 (switch "5") and CMD2 (switch "6") inputs. In this application example, the system may also be manually activated from the keypad. Press the Auditorium Speakers and/or Classroom Speakers push-button(s), then press the Fire Message push-button. Alternately, use the microphone to make an announcement. To manually deactivate a speaker circuit, press the activated (illuminated) output zone push-button.
