E2S Warning Signals horn and strobe range

Tuesday, 18 November, 2014 | Supplied by: Mechtric Pty Ltd

E2S Warning Signals has 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 range will be the next to be upgraded. The 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 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. The technology ensures that spurious signals are not picked up by the sensors to ensure reliable monitoring at all times. To comply with SIL 2 requirements, this is only carried out 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.
