Our premium plant communication system is a microprocessor controlled, software programmable, central exchange based paging system with talk back facility. We have different type of plant communication systems which include indoor systems, explosion proof systems and weather proof plant communication system. Our systems are one of the best and are highly demanded by all. Because of the high demand, we have also become a well known communication system exporter. 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. Key Features:

• Paging + Alarm broadcasting facility
• Master-Slave Configuration with facility to connect multiple master control desks
• Direct Communication between the field operators and the control room operator
• Direct communication between the two field operators (i.e. without routing any calls through central control room)
• Communication between the two field operators with the help of Master Control Station (MCS)
• Individual zone, Multiple zone and All zone selection for announcements
• Facility of connecting emergency siren over the paging channel
• Digital display at MCS for identification of field call station number / area name
• Call holding, call waiting, page priority, override and central monitoring facility at MCS
• No requirement of AC mains for operating any field equipment
• Access to features can be restricted (by software programming) for few call stations
• No correlation between the field handset stations and the loudspeakers.
• Their quantity, location and their functioning are 100% independent
• Open system to facilitate its integration with EPABX, Fire alarm etc.
• Easy and quickly expandable by adding the relevant card in central equipment
• Host of various unique and useful features

• State of the art technology
• Software programmable for communication options, features and system access
• Simple and economical field cabling
• Cost effective design and hardware
• Trouble free system
• Modular architecture, offering the flexibility to build the system block by block
• Centralized monitoring for system operation, performance and equipment healthiness
• Reduced and easy maintenance
• High flexibility and adaptability
• 100% non-blocking communication facility to all users
• Minimum downtime, easy system operation and maximum safety
• Easy and Quick to expand

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. Key Advantages :

• Reduced and easy maintenance
• Simple, reduced and economical field cabling
• Trouble free system
• Flexibility to connect the loudspeakers at longer distance.
• Modular architecture
• Flexibility to build the system for the present need with enough provision for future expansion.
• Connectivity of p. a. system with the EPABX System
• Monitoring the healthiness of all associated equipment in the PA System
• Call attention chime tome prior to all announcements
• Facility of connecting emergency siren over the paging channel
• No use of AC Power source in the field
• Highest priority for control desk paging
• Bass and Treble control to custom-tailor the frequency response, for poor acoustic or highly noisy environments
• LED Bar graph in dB scale to read the relative power
• Distribution of audio signal through buffered O/P
