2. SUMMARY AND FEATURES
The IP-A1PG is a PoE-powered Gateway Unit that integrates multiple IP Audio device by transmitting
multicast audio stream.
• Power is supplied by way of PoE (IEEE 802.3af) switching hubs.
• The IP Paging Gateway supports the following broadcasting functions:
Internal sound source
broadcasting
Multicast audio transmission up to 20 internal sound source les by
means of control input or Remote API (HTTP).
VMS broadcasting Converts ONVIF backchannel audio stream from VMS (Video
Management system) to Multicast audio stream.
SIP broadcasting SIP audio stream to multicast audio stream conversion from any
communications device that utilizes the SIP protocol, such as SIP or
IP telephone (IP-PBX) systems.
Line/Mic input
broadcasting
Multicast audio streaming from the sound source device or microphone
connected to Line/Mic input, activated by means of control input or
Remote API (HTTP).
• Orders of priority can be set among the various sound source, meaning higher priority broadcasts
can interrupt and override lower priority broadcasts.

9.4. Removable Terminal Plug Connections
Please note the following points when making connections to the control input, control output, and
speaker output terminals using the supplied removable terminal plugs:
• Do not tin stripped wire ends with solder.
Soldered wire ends will be crushed when the terminal plug screws are tightened, leading to
higher contact resistance and potentially resulting in an abnormal rise in the temperature of the
connected parts.
• Use AWG 28 – 22 wire (ø0.32 – 0.64 mm solid wire or multi-stranded wire with a cross-sectional
area of 0.08 – 0.32 mm2).
• Strip the wire end back about 7 mm (0.28").
• When connecting 2 wires or a signal cable to a single
terminal, crimp them in an insulated (twin) wire ferrule to
prevent their core wires from being separated from one
another. Use a ferrule of the dimensions shown in the gure
at right.
[Plug Connection Procedure]
Step 1. Remove the plug from the terminal.
Step 2. Loosen the terminal screw and insert a wire.
Step 3. Tighten the screw rmly.
Note
Pull on the wire to ensure that it does not
come off.
Step 4. Insert the plug into the terminal.
