Alarm Annuciator with Latest technology with Rugged Plastic Encloser :

Providing excellence with Latest Technology with Rugged Plastic Enclosures with High Strength Alarm Annunciators & Hooters

Prompt detection and rectification of any system failure or mal-operation is of vital importance for any power or process plant. PROTON Alarm Annunciators continuously monitor the various process parameters and equipment status in power-stations, process plants and these parameter are displayed at centralized control room or on control panel. PROTON Annunciators stand for instant alarming of any abnormal condition occurs during process and protect the valuable equipments. PROTON Annunciators ensure the higher order of reliability and thus provide a comprehensive service to the industry for monitoring, alarm and control of process plant parameters. These highly advanced and compact systems use the latest single chip micro-computer technology for it’s design and offer multipoint annunciation with operating sequences as per prevailing standards and with many optional features as indicated aside.

Application Areas:

Thermal power stations and sub-stations of Electricity Boards, Steel Plants, Sugar Industries,Cement and Chemical Industries, A.C. Plants, Process Plants, Heat Treatment Plants, Hotels, Fire Alarm Systems and in telephone exchange as Audio-Visual panels etc
