The higher the SIL level, the lower the probability of failure on demand for the safety system and the better the system performance. To support the safety goals of machinery and processes that strive to comply with SIL, all risks must be adequately mitigated. Even after all possible design criteria and complementary safety barriers are considered, a risk gap may still remain for many circumstances. **In such situations, a signaling solution will help narrow the risk gap.** **Systems that require SIL signaling are generally divided into two application categories: machinery alarms and process alarms.** | **Machinery Alarm Systems** > Startup Alarms > Failure Alarms > Muting Alarms (for situations where the safety barrier is temporarily disengaged such as for set-up or maintenance)   | **Process Alarm Systems** > Alarm systems for toxic gas leaks or chemical spills > High pressure and temperature situations > High voltage situations > Chemical vapor recovery systems > Natural gas pipeline, supply, and transport systems > Hazardous substance handling | | --- | --- | **PFANNENBERG SIL COMPLIANT SIGNALING SOLUTIONS ** ** For many years Pfannenberg has provided [SIL 1 and SIL 2 compliant signaling technology](https://www.pfannenbergusa.com/sil-signaling) for harsh industrial environments. **Equipped with the key safety data, the sounders and flashing lights can be integrated in the safety concept of machines and plants without any problems. **Pfannenberg SIL Conform Signaling Devices: ** **Series DS 5-SIL and DS 10-SIL** | **![DS5_DS10_SIL.jpg](https://blog.pfannenbergusa.com/hs-fs/hubfs/DS5_DS10_SIL.jpg?width=100&name=DS5_DS10_SIL.jpg "DS5_DS10_SIL.jpg")** | -
