• Automatic sound cancellationBy adopting modular design combined with latest Microcontroller technology, 'Digilarm Series 1800' provides more features than any other system available. High noise immunity is provided at very low logic/LED power, hence ideally suited for all industrial environments. 4-Annunciation channels are mounted on one sequence card module for compactness and cost reduction.

  Input derived from 'dry' field contacts, the system is supplied either in Integral on Split architecture. The visual displays are available in any Rows x Column configuration of 6 or more windows. The integral unit and the windows cabinet in case of Split system are flush panel mounting type. Audible alarm device (Hooter/buzzer etc.) and Push Buttons are generally supplied 'loose' for separate mounting but can be provided on front of the Annunciation unit itself, if so required by the customer.

  Unsurpassed versatility of the 'Series - 1800' system permits field alteration of virtually every major aspect of Annunciators operation - Working voltage, NO/NC input Alarm Sequence, First-out groups, etc.

  Use of micro controller has greatly reduced the number of components, thereby enhancing reliability. No maintenance required. Not even lamps, Long life, super bright LED's have been used. No parts that could call for replacements.
