Industrial Telephones are a product of the unique technological breakthroughs prevalent in the modern era. They facilitate communication among people located at geographically dispersed locations. No external power is required in such industrial telephones and is highly suited for a noisy environment. The presence of such an equipment offers high range of reliability and efficiency and is also being considered as a perfect replacement of conventional phones. Every industrial telephone is fitted with hook switch and a sealed keypad to avoid exposure to grime, dust or any other external pollutant.One of the salient features of industrial telephone include noise removing microphone as well. The emergency phones comprise of a stainless steel handset cord which is hearing aid compatible and remains flexible in extreme temperatures. There are several growing organizations which are utilizing emergency phones in conjunction with plant EPABX.The emergence of advanced leading edge technologies has also led to the inception of innovative interventions like Industrial Public systems and hotline P address systems which are devised to regulate the functioning of voluminous industrial units. Every industrial PA system is constituted by mixers, amplifiers and loudspeakers so that sound can be reinforced quickly. One can frequently encounter extensive application of industrial PA systems in shopping malls, industrial plants, airports, railway stations etc and are meant to ensure customer protection and suitable convenience in event of theft, vandalism or security breaches. The modern industrial PA systems ensure efficiency, scalability, flexibility, simplicity and user friendly approach in comparison to traditional PA systems.Industrial public address telephone composed of amplifier and loudspeaker offers the unique advantage of ensuring an effective communication system among people located at geographically dispersed locations. Through industrial public address telephone one can target a specific location rather than the whole premises for announcement purpose.Hotline public address systems are being extensively utilized in efficient addressing on the basis of multiple telephonic units connected through a single line using controller and Junction Boxes. Hotline PA systems are helpful in off hook services like fire alarms and emergency phone announcements in the event of accidental hazards.With the dual benefit of industrial public address/paging system one can ensure point-to-point communication among individuals or units with supreme efficiency. The private line function allows people to communicate without the use of loudspeakers. One more category of industrial PA systems include the desktop public address systems where a desktop can be attached to a uni-directional microphone and used as an effective communication medium.
