Safety Integrity Level (SIL) audible and visual signaling devices are designed to conform to SIL 1 and SIL 2 safety requirements. The devices use self-monitoring circuitry and fault-indicating contact closures to alert users of failure or initiate shut down/lock out of machinery until corrective action can be taken. In addition, the products offer full statistical data supporting conformity to SIL 1 and SIL 2 requirements.
