Overview
The ALM300 series Alarm Annunciator – Split type provides an ideal solution to alarm monitoring problems which allows an operator to monitor the alarm status of critical parameters. The fault inputs are field selectable for normally open or normally closed input operation. Use of microcontroller has greatly reduced the number of components, thereby enhancing reliability and efficiency. The special software filters of microcontrollers remove spurious faults. The incoming fault signals from the various potential free field contacts are scanned and processed, driving the corresponding LED window and hooter contact in order to announce the fault. The ALM300 has the facility of first fault identification wherein from a group of faults the occurrence of first fault is indicated in a different manner as compared to the subsequent faults. The super bright LEDs ensure a long and absolutely maintenance free window life along with good visibility and low power consumption. Split type Alarm Annunciator unit consists of base unit and facia unit.
