PLANT COMMUNICATION SYSTEM (PCS) is a microprocessor controlled, software programmable, central exchange based paging system with talk back facility.

The system comprises of page channel and party channels for two-way communication facility between the control room and the field.

Page Channel provides loud speaking facility and is used for broadcasting messages or issue instructions or to locate field operators in the plant. The announcements made by the users are heard over the field loudspeakers.

Party Channel is used for carrying prolonged conversations in private mode, which is not heard over the loudspeakers. The system possess multiple party channels i.e. one dedicated channel for each field handset station. Thus each field operator can carry his separate, independent and simultaneous conversation.

The field call stations and loudspeakers are installed at various locations throughout the facility. The person can communicate from any field call station of the system.

The loudspeakers and field call stations are indoor type for indoor areas, weatherproof type for outdoor safe (i.e. non-hazardous) areas and explosion proof type for hazardous areas. The loudspeakers are available in different wattages & sound pressure levels and in different sizes & constructions to meet all types of the requirements.

The system provides excellent reproduction of sound, clear audible announcements and high intelligibility of speech, even in high noisy areas.

The public address systems being manufactured by us are of premium in their functioning and are available in various sizes & configurations to suit all kinds of functional needs. The system is designed for use in harsh & hostile industrial environments characterized by indoor & outdoor usage, presence of dust & water ingress, corrosive atmosphere, extreme & varying temperature, presence of hazardous & explosive gases, rough usage, accidents, emergencies and loud ambient noise due to industrial processes.

It is a centralized amplifier based system thats been designed to provide voice paging and to broadcast alarm tone during emergencies.

The system can transmit alarm tone and routine voice messages, from a central location, to all or selected areas of the facility, in a reliable and safe manner, by the use of loudspeakers.

The entire operational area / facility can be divided into one or more zones, which can be accessed independently either for announcements or for alarm broadcasting. The loudspeakers are installed in these zones.

There are no limitations to number of zones in the system or number of loudspeakers in each zone. Each loudspeaker is connected to the central equipment for amplification and other control functions.

Depending on the surrounding environment, either flameproof loudspeakers (for hazardous atmospheres) or weatherproof loudspeakers (for safe & non-hazardous atmospheres) or indoor loudspeakers (for indoor areas) are installed in each zone. The loudspeakers are available in different wattage, sizes, types and constructions.

The system is designed to offer clear reproduction of sound and intelligibility of speech even in high noisy areas.

Multiple control desks can be installed in the same system, for paging access (with priority) from more locations.

The system uses high reliability amplifiers with built in over load protection circuitry, short circuit protection, open circuit protection and thermal protection.
