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.
A smart combination
of software and hardware removes the need for time-consuming inspection and
test of each individual warning device by intelligently reading the sound
output of the horn or the light emitted by the strobe to check it is working
properly. State-of-the-art technology ensures that spurious signals are not
picked up by the sensors to ensure a reliable monitoring at all times. To
comply with SIL 2 requirements, this is only done during an automatic test of
the system and any faults are reported back when the system returns to its
normal monitoring state. Communication
with the system control panel can be configured in two ways: either a contact
is closed or a series resistor is brought into the monitoring circuit in the
event of a fault. A dedicated SIL 2 information page can be found at http://www.e2s.com/information/sil2-certified-audible-and-visual-warning-signals.
The web site www.e2s.com has full product information, distributor contact details and a useful
reference section, with technical bulletins and white papers on various aspects
of warning signalling, freely available as a resource for specifiers, system
designers and consultants.
