Introduction :
PAGE PARTY SYSTEM is a paging system with talk back facility and is mainly used in industrial plants for the following communication functions.
The system architecture comprises of FIELD HANDSET STATIONS / talk back stations (installed at various locations in the plant), PAGING LOUDSPEAKERS (installed at various locations inside the plant) and the CENTRAL PAGING CONTROLLER. The Field Handset Stations and Field Loudspeakers are: Indoor desk mountable type (for use in indoor areas), Weatherproof IP66 Type (for use in outdoor safe & non-hazardous areas) and Explosion Proof - Flameproof type (for use in outdoor hazardous areas). The user can select the suitable model depending on the plant areas where they are to be deployed. The use of Control Room Master Control Station (MCS) is purely OPTIONAL. The users can have Page-Party system with or without MCS.
The system provides Multiple PAGE CHANNELS and Multiple PARTY CHANNELS and these channels are used by the users for two-way communication. The system can provide either Single PAGE CHANNEL or Multiple PAGE CHANNELS and Multiple PARTY CHANNELS. It can offer up to 8 Nos. of Page Channels (i.e. up to 08 paging groups can be formed). The Number of PARTY CHANNELS is unlimited & is equal to number of Field Stations deployed in the system. Due to availability of Multiple Page & Party channels, multiple field operators can carry their independent & simultaneous communication.
The Calling individual goes to any of his nearest field station, lifts the handset off the station, selects the desired page channel (simply by dialing the access code) and speaks into the handset to broadcast his message. This message (announcement) gets heard over all the loudspeakers of the selected page channel. On hearing the announcement over the loudspeakers, the called individual goes to his nearest field station, lifts the handset and answers the page call (through an access code) and he immediately gets connected to calling individual on their respective party channel and they both starts conversing. The page channel sets free. This conversation between the two (on party channel) is not heard by any other users and nor it is heard over the system loudspeakers. The two individual can talk to each other as long as they desired. As the Page Channel is free (idle), any other individual in that group can access it and can get connected to another individual in the above fashion…and so on.
