Beacons Offer LED As Light Source
E2S Warning Signals has introduced new capabilities for EEx d versions of its BEx family of explosion-proof beacons and MB Series marine beacons. Now, the light source in both families can be specified as an array of high-intensity LEDs, rather than Xenon tubes. The change is designed to enable nine modes of operation to be specified.
The color of the protective domes is matched with the wavelength of the relevant LED light source to maximize the output. Available in amber, red, blue, green or clear versions, users have a choice of nine different modes, including four flash modes, four rotating modes and a steady state mode.
Devices provide three remotely selectable visual alarm stages. In addition to the standalone beacon, the units are available combined with a 112dB(A) sounder in a single housing, offering a method that provides both audible and visual signaling. BEx versions are approved to IECEx, InMetro and GOST R.
The high-output LEDs are built to be mechanically robust for environments where shock and vibration are present. They are also designed for efficiency, producing a high-intensity light source over the lifetime of the device without significant reduction due to aging.
