Industrial Duplex Multi-Party Paging Broadcasting System Uer Manual
Chapter 1 System Introduction
System Features
The "Multi-Party Talk" Paging system PA3 is designed for communication in industrial environments.
A: It is suitable for high noise, corrosive atmospheres, hazardous areas and extremes of temperature, dust and humidity create hostile environments.
B: The "Multi-Party Talk" system have two operations: the first one is group calling through pick-up handset and pressing one button to auto-dial; The other one is two-way private intercom in one line or more two-way groups calling and can be allowed 12 persons communication at most.
C: The system also can be connected to external network, and the extension can call other phones outside of the network.
1. To initiate communication or broadcast over the system to all other station, the operator at one of the station lifts the handset from the cradle, presses * to call and speak to all the other party.
2. All the stations rings and auto-answers. All the other user at all other station can joins the conversation by lifts the handset and speaking into the handset. The system allows all party simultaneous conversation without cross-talk or interference. After conversation each station will auto off to release the line.
3. To initiate communication or broadcast to one of the other station, the operator at one of the station lifts the handset from the cradle, presses ID number (extension number) which you want to call, and speak to them. After conversation each station will auto off to release the line.

Afer pick up the hook; 1.press L1 +outline number:calling outling.2.press L2 or L3, press #+ID number: single calling(calling by one to one). 3. Press L2 or L3, press #+99999: whole calling. 4. Press L2 or L3, press #+ group number: group calling 5. Press L2 or L3, press speed dial number at least three second. When hear the dial tone can release the button.
Open broadcast system function to make a broadcast call
b:Duplex call
After the called user pick up the hook. Caller can make a duplex calling through the handle microphone or press the hands-free button.
c.Channel switching
After the called user pick up the hook. Caller can make a duplex calling through the handle microphone.
d. Channel switching
Rotary Switches operate 3 ~ 6 communication channel selection.
e. Boardcasting mute setting
Maintainer can setting the call volume via the mute switch on the motherboard;
f.Using PSTN to make outline telephone communication
Outline user can make a boardcasting calling and communication via outline telephone station to PSTN.
g.Expansion easy to use
Each station works independently. All the telephone station work via 8-14 core cable in parallel. If any one station failure does not affect the normal operation of other user stations. Users can according demand to expand station or relocation. It's unlimited.

Structure
Desktop call station
The call station make up by the desk telephone and power junction boxes, of which the telephone

DimensionsL: 250 (mm), W: 225 (mm), H: 115 (mm)junction box DimensionsL: 210 (mm), W: 305 (mm), H: 125 (mm)

The telephone can external connect a 5W speaker if needed.

Outside line telephone station
Outside line telephone station junction box will be installed in control room be convenient for installation and maintenance.
Earth Wire
Indoor wall-mounted telephone station,Outdoor wall-mounted telephone station,Power supply wiring box,Cable junction box,the metal shell to be reliably grounded when installing.
Piping, cable laying
To meet the industrial and mining complex, harsh field environments,the cable should be metal piping laying.
System uses special all shielded cable.
To avoid electromagnetic interference, the wiring on the cable channel or cable tray, should avoid high-voltage, high-current, high magnetic field environment. Implementation of the relevant provisions of the communication cabling.
Using metal spring hose to connect cable pipes with terminal

system connection
On the cable before terminals work,the core wire which is connected to the same terminal need to be compression joint by Y-shaped terminal or round-shaped terminal to ensure good conductivity properties
Line sequence should be defined before connecting 8 to 14 core cable, to ensure that each terminal are in line with pre- defined easy on-site installation and future maintenance ;
System connection diagram shown in Figure 7 .
