Safety signals
Safety Integrity Level (SIL) audible and visual signaling devices are specifically designed to conform to SIL1 and SIL 2 safety requirements. They utilize self-monitoring circuitry and fault-indicating contact closures to warn of failure or initiate shutdown/lockout of machinery until corrective action can be taken. The signaling solutions from Pfannenberg are a safe choice for applications such as machinery startup alarms, marchine guard muting alarms, process upset alarms and evacuation alarms.
