industrial paging system description

Industrial Paging System PA3

We can provide free paging system design for university campus, restaurant, hospitallibrary, production line, nuclear power station tunnel, etc.We can provide different systems in a targeted way. We can also provide overhead loudspeakers, column loudspeakers, amplifiers, phone paging amplifiers and emergency intercom systems.


The paging system is a communication system based on communication technology that communicates with the public through speakers. Through the system, you can quickly and accurately publish announcements and notifications to multiple areas.The system permits for unidirectional communication to an outsized audience. notwithstanding the published supply, a unidirectional paging system lets the speaker give clear, amplified directions throughout a facility. The paging worker speaks a message into a phonephone which message is then broadcast through a network of speakers. Messages may be recorded and broadcast at a later time.


Five blessings Of Paging Systems


There square measure variety of benefits to employing a unidirectional paging system versus different suggests that of mass communication:

Signal transmission relies on stable networks

A paging system is hard-wired into the building's infrastructure, permitting reliable mass communication.

A network of speakers make sure that a message is communicated to each space of a building at the same time. it is also potential to send pages to specific building "zones" if required.

Another key good thing about a paging system is that no dedicated broadcast mechanism is needed. AN worker will merely acquire the phone, choose the paging system and broadcast to the complete building.

A loop is a communication link that can be used normally even if a line is broken


Some Common Use Cases For Paging Systems

Paging systems is accustomed send a spread of messages. the foremost common example of a paging system is fast communication between staff in an exceedingly retail setting. A emporium cashier will request help from another department to answer a client question. When the production workshop needs other departments to make the page.

One of the most important USES of paging is to give correct instructions to staff in emergency situations.We provide the paging system for colleges and universities, we provide different types of loudspeakers, paging instruments and speakers, amplifiers, microphones, mixers and so on for convenient use in different scenes. Our voip paging system also provides capabilities to provide emergency paging systems.

Industrial Multi-Party Paging System can be broadcast over a loudspeaker as well as two or more people.Using the system to start a multiparty call or broadcast, the operator picks up the receiver from the stand at the station, presses the pish-to-page button next to the receiver and speaks with the microphone.Phones at all other stations will ring and answer automatically. Other users can pick up the phone and join the conversation. The system is able to communicate without crosstalk and without interference. When the call is over, you just hang up.

The paging system is a comprehensive industrial paging system designed for large voip industrial telephones and broadcast amplifiers in large public places such as hospitals, hotels, warehouses, and schools.

1.1 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 up to 99 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.
