“Caltech’s exciting new relationship with E2S represents a further step towards delivering an even greater range of high quality product ranges for clients.”

MED compliant to the latest directive for marine applications across all voltages. Third party approvals are provided by default across the ranges to ensure compliance with the latest standards and directives wherever the application is located. The M range signals feature robust, thermoplastic fire-retardant enclosures with 316 (A4) stainless steel mounting brackets – ideal for applications in harsh environments where Type 4/4X/13/3R IP66/67 protection is required. For applications that require an even higher level of sound output the new MA2H alarm horn sounder is now available. Utilising the new E2S ‘2H’ super high output flare horn – engineered to maximise audible signalling performance across the widest range of frequencies – the MA2H offers a sound level of up to 130dB(A). The alarm horn sounder DC voltage range is now 10 to 60Vdc whilst the AC versions now include a universal power supply suitable for inputs of 100 to 240Vac. High voltage DC versions are available on request. The STEx family

encompasses audible, visual, and combined warning devices and manual call points, all employing 316L stainless steel enclosures. Designed for installation in the harshest of 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 STEx family to be employed in the most arduous of 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 omni-directional horns, are available with 64 alarm tone frequency patterns and outputs up to 123dB(A). STExB beacon light source is available in either a 10, 15 or ultra-bright 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 – reducing installation time and cost. The field-replaceable colour lens filters feature a prismatic design for enhanced light output, generating

industry-leading candela values. The STExCP8 call points, approved for deployment in SIL 2 complaint systems, are available with the innovative 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. Stainless steel blanking plugs are provided with all units; cable entries are M20, ½” NPT, ¾’’ NPT or M25. All external hardware such as beacon dome guards and mounting brackets are 316 (A4) stainless steel as standard. Building on legacy Over the last 25 years, Caltech has built up a core group of high-end electrical and control suppliers who they work closely with to give customers an efficient and quality service. Caltech also works closely with engineering houses, contractors and on-site engineers to help develop solutions for a wide range of applications in sectors such as pharmaceutical, biomedical, oil and gas. The new relationship with E2S offers a perfect partnership in that endeavour.
