General Information
Product Overview
The Model 10370-701 VoIP Speaker Amplifier Interface assembly broadcasts audio to personnel
throughout a facility over an existing network via external speaker(s) or connection to a central amplifier
speaker system. The amplifier interface is easily added to existing 10/100 BaseT Ethernet networks with
minimal cost and effort.
The VoIP speaker amplifier interface includes an integrated speaker amplifier that supplies up to 30-watts
of audio output power to an existing 8-ohm speaker or combination of speakers equaling 8 ohms. The
ability to use any speaker or horn/driver combination allows selection of speakers that meet the coverage
and environmental requirements of any specific area.
The VoIP speaker amplifier interface includes a 600-ohm, 0 dBm audio output. This output can be
connected to the audio input of a central amplifier or any equipment that requires a 600-ohm audio input.
The VoIP speaker amplifier interface also includes two dry-contact type A (normally open) outputs. Each
output is programmable for a variety of uses, such as activation of a strobe in a high noise area or
initiating a door latch remotely.
The VoIP speaker amplifier interface provides flexibility to address a diverse range of applications. A
wide variety of functions are achievable by altering the configuration data stored in the non-volatile
memory. The configuration options include:
•webpage configuration
•configuration file

Features and Functions
GAI-Tronics’ Model 10370-701 VoIP speaker amplifier
interface has the following features:
• 10/100 BaseT Ethernet network connection
• one-way broadcasting from an IP network
• weatherproof enclosure
• 30-watt speaker amplifier (into an 8-ohm speaker load)
• 600-ohm audio output
• two dry contact relay outputs
• SIP compatible (RFC3261)
• real-time alarm reporting via SNMP, Syslog, or TMA
software
• configurable via web page or download
• multicast capability, up to eight addresses
System Requirements and Limitations
Systems containing VoIP speaker amplifier interface
assemblies require A 100 BaseT Ethernet network with a SIP
(Session Initiation Protocol) server. The operation of this equipment is limited by the customer’s LAN
media capabilities and the services available at the end point. The performance of each VoIP speaker
amplifier interface is dependent on the provision of sufficient bandwidth and network protocol
prioritization to give the quality of service required. The setup, installation, and software version of key
components, such as switches and routers, can significantly affect this equipment’s operation. Improper
connections or loose cables can also affect their operation.
The VoIP speaker amplifier interface requires a local 120/240 V ac power source for amplifier output
operation over 8 watts. PoE (Power over Ethernet) is an option for installations requiring less than 8-
watts of speaker audio output.
The following network services provide required and optional functionality (This may vary widely
depending on how the network is deployed):
• SIP proxy server (to route calls)
• SIP registrar server (frequently combined with proxy servers)
• TFTP server (for downloading configuration files).
• TCP Syslog server (for reporting alarms and external inputs)
• SNMP server (for reporting via simple network management protocol)
• SNTP server (to synchronize the internal clock)
• STUN server (for NAT firewall traversal)
• PoE (Power over Ethernet) (for less than 8-watts audio output)
Dedicated systems, such as Gatekeepers, VoIP-enabled PABXs or soft PABXs may also provide these
functions. GAI-Tronics’ VoIP speaker amplifier interface supports SIP to RFC3261 call control
signaling.

Multicast Broadcasts
The VoIP speaker amplifier interface can receive multicast broadcasts. Multicast allows a single audio
stream to be sent to multiple end points simultaneously, achieving multi-point paging or public address
functionality over IP. Multicast requires the use of a SIP server that specifically supports multicast
functionality and each interface must be configured (enabled) to receive multicast packets.
Installation
Safety and General Information
Installation must be performed by qualified service personnel in accordance with the National
Electrical Code or applicable local codes.
Power Sources—Operate this unit only from the type of power source indicated on the label.
Contact qualified service personnel if unsure of the type of power supply to use.
•Refer to operating instructions for units intended to operate from battery power.
•Use only the recommended approved power supplies with units intended to operate with external
power supplies.
•The power source must comply with EN60950 for units intended to operate with a limited power
source. Substitutions may damage the unit or cause fire or shock.
Electromagnetic Interference/Compatibility
Electronic equipment may be susceptible to electromagnetic interference. If you experience interference,
visit the FCC website at http://www.fcc.gov for possible solutions.
Safe Handling of CMOS Integrated Circuit Devices
Many of the integrated circuit devices used in communications equipment are of the Complementary
Metal Oxide Semiconductor (CMOS) type. Because of their high open circuit impedance, CMOS
integrated circuits are vulnerable to damage from static charges. Care must be taken handling, shipping,
and servicing them and the assemblies in which they are used.
Even though protection devices are provided in CMOS integrated circuit inputs, the protection is effective
only against overvoltage in the hundreds of volts range such as is encountered in an operating system. In
a system, circuit elements distribute static charges and load the CMOS circuits, decreasing the chance of
damage. However, CMOS circuits can be damaged by improper handling of the modules, even in a
system.
To avoid damage to circuits, observe the following handling, shipping, and servicing precautions:
•Prior to and while servicing a circuit module, particularly after moving within the service area,
momentarily touch both hands to a bare metal, earth-grounded surface. This will discharge any static
charge that may have accumulated on the person doing the servicing.
NOTE:Wearing a conductive wrist strap will minimize static build-up during servicing.
•Whenever possible, avoid touching any electrically conductive parts of the circuit module with your
hands.
•Power down the unit before installing or removing the circuit module.

•When servicing a circuit module, avoid carpeted areas, dry environments, and certain types of
clothing (silk, nylon, etc.) because they contribute to static build-up. Similarly, disconnect the test
probe prior to removing the ground lead.
•All electrically powered test equipment should be grounded. Apply the ground lead from the test
equipment to the circuit module before connecting the test probe.
•If a circuit module is removed from the system, it is desirable to lay it on a conductive surface (such
as a sheet of aluminum foil) which is connected to ground through 100-kilohms of resistance.
•When soldering, be sure the soldering iron is grounded and has a grounded tip.
•Prior to connecting jumpers, replacing circuit components, or touching CMOS pins (if this becomes
necessary in the replacement of an integrated circuit device), be sure to discharge any static build-up
as described in procedure 1. Since voltage differences can exist across the human body, it is
recommended that only one hand be used if it is necessary to touch pins on the CMOS device and
associated board wiring.
•When replacing a CMOS integrated circuit device, leave the device in its conductive rail container or
conductive foam until it is to be inserted into the printed circuit module.
•All low impedance test equipment (such as pulse generators, etc.) should be connected to CMOS
device inputs after power is applied to the CMOS circuitry. Similarly, such low impedance
equipment should be disconnected before power is turned off.
•Replacement modules shipped separately from the factory will be packaged in a conductive material.
Any modules being transported from one area to another should be wrapped in a similar material
(aluminum foil may be used). Never use non-conductive material for packaging these modules.

Cable Installation Safety Considerations
Interconnecting communication and Class 2 dc power cables should be separated from electrical light or
other Class 1 circuits by at least 2 inches. The exception is where Class 1 wiring or power circuits are run
in a raceway, or are metal-sheathed or metal-clad, or are permanently separated from the conductors of
the other circuitry by a continuous and firmly fixed nonconductor such as porcelain tubes or flexible
tubing in addition to the insulation on the wire. Communications cables and in-building wiring should be
listed and marked for the purpose according to NEC Article 800.
