Master Alarm Database Rationalization

SILAlarmTM is a tool for facilitating the alarm rationalization process and documenting the results in a master alarm database. It guides a rationalization team through a systematic process of reviewing, justifying and documenting the design of each alarm, ensuring compliance with a corporate or site alarm philosophy document. 

It supports data exchange with new (greenfield) and existing (brownfield) control systems via import / export to MS Excel. Developed in accordance with the ISA 18.2 standard and the EEMUA 191 guideline, it can be used by novices and experts alike to comply with alarm management good engineering practices.

Guiding you through the Rationalization Process

Tailorable to your Alarm Management Practices

Having an alarm philosophy document in place is a pre-requisite to a successful alarm rationalization. SILAlarm can be setup to take on the rules defined in your philosophy document. This ensures consistency and traceability by enforcing these rules during the rationalization process. Typical philosophy-specific settings include: 

  • Alarm Prioritization (number of different alarm priorities / priority names, prioritization matrix).

  • Consequences of Not Responding (impact categories and descriptions for evaluating potential consequences).

  • Operator Response Time.

  • Alarm Classes.

  • Alarm Tuning (deadband / hysteresis, on / o delays).
