The FB-8800 Safety System is the FireBus offering in the high reliability/high availability arena and caps our three platform product offering.

The FB-8800 System is intended for use as part of a programmable electronic system as defined by IEC 61508. It is suitable for safety functions up to safety integrity level 2 (SIL2). 

The system employs a 1oo1D (i.e. 1 out of 1 with diagnostics) architecture to achieve SIL2.  

FB-8800 Safety Logic Solvers may be used in redundant mode to increase system availability, but this is neither required by, nor relevant to, the safety-related performance of the system. 

Configuring and programming the system must be via a FireBus software program known as the “Safety Logic Workbench”. 

In addition to completing the actions specifically related to the FB-8800 Safety System, it is necessary to satisfy the wider requirements of IEC 61508.  This includes such elements within the framework of the safety lifecycle, such as hazard and risk analysis and defining the safety requirement specification.  

This work must be carried out through appropriate and competent Safety Management procedures and staff.
