Public Address System

Public Address - General Alarm System / PA-GA system

   
 

PA-GA is centralized amplifier based, industrial Public Address system (audio communication SYSTEM), which is used in industrial plants for the following MAIN functions.

Routine public address announcement (voice paging) during normal operations

Broadcasting pre-recorded STORED voice messages / Alarm Tones during emergency situations. These messages could be Safety / Security / Fire alarm messages or Evacuation instructions or public utility general messages

Interface with PBX system for paging announcements from telephone intercoms
Interface with External Visual Beacons (signaling devices) in high noisy areas
   
Environment:

The system is suitable for use in harsh & hostile environment characterized by: indoor & outdoor usage, Presence of dust & water ingress, Corrosive atmosphere, Explosive gases & particles, varying temperature, loud ambient noise, people’s safety etc.

   
PA-GA system Hardware:
The system broadly comprises of:
System rack cabinet
Desk top Microphone access station (Access Units) with zone selection facility
Mixer amplifier, Power amplifier modules
Control panel – Page controller unit
Prerecorded–Stored Voice message (or audio Alarm tone) generator unit
Loudspeakers
External flashing beacons / Signaling devices interface
Telephone interface module
Features:

The system offers clear reproduction of sound and intelligibility of speech even in high noisy areas.

The users can make routine voice announcements or can transmit alarm tone, from Microphone Access Station, in a reliable and safe manner.

The entire operational area (facility) can be divided into number of sub-areas called ZONES. The loudspeakers are installed in these zones. The users can make either Individual Zone wise announcements or Multiple Zone wise announcements or ALL ZONE announcement.
There are no limitations to number of zones in the system and to the number of loudspeakers deployed in each zone. Each loudspeaker is connected to the central equipment for amplification and other control functions.
Wide range of high performance loudspeakers. Depending on the plant environment, the loudspeakers can be either explosion proof loudspeaker (for use in hazardous areas) or weatherproof loudspeaker (for use in safe areas) or indoor loudspeaker (for use in indoor rooms / indoor areas).
The system uses high reliability amplifiers having built in over load protection, short circuit protection, and thermal protection. Each amplifier module is of 240 watts. The system is available in standalone amplifier configuration or in N+ 1 standby amplifier configuration. The amplifier hardware has gain control, bass control, treble control to custom tailor the frequency response, for poor acoustic or high noisy areas.
During an emergency or fire situation, the stored voice message (or stored audio alarm tones) is broadcasted over the system loudspeakers. The stored message is actuated through potential free contact from fire alarm or other control system. Each Voice message generator module has the storage capacity of 08 messages, which can be increased to 16 / 24 /32 / 40 … and so on messages. The message can be broadcasted over all the loudspeakers of the PA system in ALL ZONE mode or it can be broadcasted in a particular zone area. The messages have priorities amongst themselves, with Message #1 having the highest priority. Thus the sequence for broadcasting the messages can be configured / set at site as per the need.
The selection of stored message for broadcasting can also be done manually, from an external MESSAGE ACCESS CONSOLE (Optional)
Through telephone interface module, the PA system is integrated to client’s EPABX system. This allows the users to make paging announcements over the PA system loudspeakers
through their intercom telephone.
In addition to the audio communication network, visual warning BEACONS can be deployed in noisy areas to extend the reach of PA-GA system.
