Alarm Annunciators

Microprocessor / Microcontroller Based Alarm Annunciators :-

In the process there may be an alarm or trip condition. This alarm condition or trip condition occurs at a set point of a parameter in the process. To indicate this we manufacture highly efficient, accurate and intelligent Microprocessor Based machine called Alarm Annunciator. An Alarm Annunciator continuously scans these fault conditions, which may occur during any process operation. Fault condition is indicated by flashing of the LED based facia windows of Annunciator and by sounding the audio Hooter and the operator can take necessary corrective action.

Pacific Annunciator can scan all the parameters of the process to report a faulty condition if any. In other words there is no limitation on the number of inputs to the Annunciator & can be tailored according to the process. The Annunciator inputs are programmable and site selectable for NO(normally open) or NC ( normally close) sensing and are isolated optically. We have wide range of annunciator to fulfill different types of requirement.


" We have carried out Environmental and Electrical type tests from ETDC Pune and ERTL Mumbai on our Annunciator Unit."
