SIL 2 Compatibility Added to Horn and Strobe Families

Safety Integrity Level, SIL, is a measure of safety system performance expressed in terms of probability of failure on demand (PFD). In the oil and gas industry, particularly in the fire and gas detection systems where safety integrity is critical, SIL 2 is becoming a common standard across systems. To meet the growing demand in the oil & gas industry, E2S Warning Signals, the leading independent audible and visible warning device manufacturer, has recently added additional fault monitoring to give SIL 2 compatibility to its products.

Initially available for its BEx explosion proof 117 dB(A) horns and 5, 10 and 15 Joule strobes, its explosion proof GNEx GRP family will be the next one to be upgraded. In large petro-chemical installations, the safety-critical warning devices are installed over large distances, so central monitoring is a key requirement. While fire and gas detection systems continually monitor the integrity of the cabling, the warning devices themselves are not checked. The new SIL 2 technology in the E2S horns means that the functionality can be remotely checked and an alert sent to the control panel in case of any fault.
