Functional-safety evidence
Functional Safety / SIL Certificate for safety-rated detectors
Document-specific functional-safety assessment of a product or subsystem for stated capabilities and constraints.
Where it matters
Where Functional Safety / SIL Certificate applies
Important when a component is proposed within a SIL-verified function and its safety manual and assessment data are needed.
Process shutdown
Programmable safety controls
Safety-related interfaces
Certification coverage
How to interpret this certification
Each certificate covers specific products and uses. These details explain what is covered.
FS SIL
Understanding the mark
What the mark or label means
A functional-safety certificate normally names an assessment body, product, revision, IEC 61508 capability and conditions. There is no single global 'FS-SIL' mark that replaces the certificate and safety manual.
Fire safety products often covered
- Safety-rated detectors
- Logic solvers
- Relay and interface modules
- Shutdown actuators
- Programmable fire-and-gas controls
Points to check before you buy
- 01
Match hardware and software revision to the certificate schedule.
- 02
Read the safety manual for architectural constraints, failure data and proof-test requirements.
- 03
Check whether the certificate states a maximum SIL, systematic capability or a particular subsystem type.
Before you buy
What to check before relying on this certification
Certification is normally limited to a named model, configuration, standard and use. These checks turn a marketing claim into a procurement record.
- 01
Identify the safety function, required SIL and demand mode; do not assign SIL to an entire plant by association.
- 02
Review the certificate and safety manual for systematic capability, hardware constraints and architectural limits.
- 03
Use the stated failure rates, proof-test interval, diagnostic coverage and useful lifetime in the verification calculation.
- 04
Confirm the approved configuration includes the application software, commissioning, proof testing and lifecycle management requirements.

Frequently Asked Questions
What documents should come with a SIL-capable product?
Request the current certificate, assessment report where available, safety manual, failure-rate data and proof-test instructions.
Can I use the certificate without the safety manual?
No. The safety manual contains the conditions and assumptions needed to use the component in a verified safety function.
Does Functional Safety / SIL Certificate apply to every product made by a certified brand?
No. It normally applies only to the models, variants, uses and conditions named in the current certificate or listing.
What should I include in a purchase order?
State the exact model, required certification and standard, destination market, documents to be supplied and any system compatibility or witnessing requirements.
