INTRODUCTION:EL AM-101 is highly reliable microprocessor basedannunciator unit that is used in Power Plants, Grid Station,Substations & industrial Panels for providing supervisorycontrolThe general purpose is to provide supervision in theprocess occurring in IPPs, Grid Stations, industries & togenerate an alarm for any abnormal condition byilluminating respecting LED based window, commonaudible alarm by using any audible device (bell, hooter,siren)

OPERATION CRITERIA:The annunciation event is indicated by the input signalchanging from low to high voltage level. Each event has adedicated display Window with user Defined text messagewritten on it. AM-101can be modified to handle differentinput signal voltage levels.Contrary to conventionalannunciator AM-101 is equipped in For illuminating thedisplay windows the light bulbs have been replaced bylonger life super bright LEDs, thus practically eliminatingthe need of frequent bulb replacement.

In order to distinguish between noise signals &fault signals, it takes 200m sec to annunciate fault window& actuate the audible alarm.

THEORY OF OPERATION:

Due to the flexible architecture, all the standard sequencescan be incorporated. The basic function of anAM-101 is todetect faults or events at its inputs, (terminated outside thecase) and indicate that, by flashing pertinent windows,followed byACKNOWLEDGE, and RESET etc

Once an input is energized, the lights on the relevantwindow start flashing and the hooter comes on. Theduration of flash rate is sufficient for the inscription ofthe function to be read easilyOn pressing the ACKNOWLEDGE button, theindication flashing will be stopped, and light on thefault window will be kept ON continuously. If faultsignal is removed before the RESET push button ispressed, the window starts flashing again.But in a special model under above scenario the flashrate will be half of the initial flash rate, to indicate theremoval of fault

�

�

�

�

�

�

The RESET is then pressed to extinguish the windowLEDsIn case of persistence of fault, the window shallcontinue to stay lit even when the reset button ispressed.If another fault is energized before having the previousevent cleared the scheme re-functions the same way asdescribed above.The LAMP TEST push button is pressed (whenrequired) to test all window LEDs by lighting themsimultaneously

�Others:�

�

Independent hooter reset input available other thanavailable in STMACKNOWLEDGE, RESET and LAMP TEST inputsavailable in STM, a separate independent input forhooter silence operation is available in SPMs.Built-in memory to display the order of occurrence ofevents (SPMs).
