Bharti Technologies provide a centralized amplifier-based public addressing system in Abudhabi, Dubai that’s been designed to provide voice paging and to broadcast alarm tone during emergencies.
The public Address system is designed to offer clear reproduction of sound and intelligibility of speech even in high noise areas.
The public Addressing system uses high-reliability amplifiers with built-in overload protection circuitry, short circuit protection, open-circuit protection, and thermal protection.
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 the number of zones in the system or the 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 wattages, sizes, types, and constructions.
Multiple control desks can be installed in the same system, for paging access (with priority) from more locations.
Key Advantages Of Public Address System :
