E2S STEx warning signals and beacons

The explosion-proof and flameproof STEx range from E2S Warning Signals encompasses audible, visual and combined warning devices and manual call points, all employing 316L stainless steel enclosures. Designed for installation in harsh onshore and offshore environments where corrosion is a particular problem, the units are IECEx and ATEX approved for Zones 1 and 21 for use in hazardous areas containing both gas and dust. Extended certification and operational temperature ranges enable the range to be employed in arduous applications. Members of the STEx family are also DNV approved for on-deck marine use.

The STExS alarm horn sounders, with a choice of traditional flared or omnidirectional horns, are available with 64 alarm tone frequency patterns and outputs up to 123 dB(A). The STExB beacon light source is available in either a 10, 15 or ultrabright 21 Joule Xenon strobe, halogen rotating or an array of high-output LEDs. STExC combination signals contain both Xenon strobe and audible signals in one compact enclosure. The field-replaceable colour lens filters feature a prismatic design for enhanced light output generating high candela values.

The STExCP8 call points, approved for deployment in SIL 2 complaint systems, are available with the E2S termination unit enabling EOL and series devices to be added in the field without disturbing field wiring. The call point range is available in four operating mechanisms: traditional break glass with plastic-coated safety glass, push-button, push-button with tool reset and momentary action push-button.
