Multispectrum IR Systematic Capability:
Flame Detectors The Product has met manufacturer design process requirements of Safety
Integrity Level (SIL) 2. These are intended to achieve sufficient integrity against
systematic errors of design by the manufacturer.
A Safety Instrumented Function (SIF) designed with this product must not be
used at a SIL level higher than stated.
Random Capability:
The SIL limit imposed by the Architectural Constraints must be met for each
element.
