E2S BExCS110-05 Explosion-Proof Alarm & Beacon

Overview

E2S BExCS110-05 is an explosion-proof combined alarm horn sounder and xenon strobe beacon engineered for reliable audible and visual warning in hazardous area fire, gas, and process safety systems. Manufactured by E2S, a British specialist in explosion-proof and weatherproof warning signal equipment, the E2S BExCS110-05 delivers up to 117 dB(A) of sound output across 32 selectable alarm tones alongside a high-intensity xenon beacon rated at 120 candela effective intensity, packaged in a rugged, marine-grade aluminium enclosure certified for Zone 1, Zone 2, Zone 21, and Zone 22 hazardous locations.

As the official authorized partner and exclusive regional representative for E2S, Seven Star LLC proudly supplies the E2S BExCS110-05 explosion-proof alarm and beacon to oil and gas, petrochemical, and marine facilities across Oman and the wider GCC. Every unit shipped through our regional warehouse carries full E2S documentation, ATEX and IECEx certification, and factory-backed warranty, giving safety engineers in Muscat, Sohar, and Salalah a locally stocked, authorized source for hazardous-area alarm equipment instead of relying on grey-market imports with uncertain traceability.

Operating Principle

The E2S BExCS110-05 combines two independent warning functions in a single certified enclosure. The audible section drives a high-output electronic sounder through a flame-proof horn, generating up to 32 distinct alarm tones with three remotely selectable volume and pattern stages, allowing a single device to distinguish between fire, gas, and general evacuation alarms simply by switching tone. The visual section uses a xenon flashtube beacon flashing at 1 Hz, mechanically secured against shock and vibration and fitted with a reverse-polarity protection diode, producing a nominal 500,000 candela peak output (39,463 cd measured) and 120 cd effective intensity through a UV-stable, field-replaceable lens available in amber, red, blue, green, clear, magenta, or yellow.

Both sounder and beacon are housed in an explosion-proof, flame-proof enclosure certified to Ex db IIB / Ex tb IIIC ratings, meaning the device can contain and safely dissipate an internal ignition without propagating it into the surrounding hazardous atmosphere. Automatic multi-beacon synchronisation and a flip-flop alternating mode allow several E2S BExCS110-05 units to flash in unison or in sequence across a plant, giving operators an unambiguous, plant-wide alarm pattern rather than a scattered, uncoordinated response from independently timed beacons.

Engineering Design of the E2S BExCS110-05

The E2S BExCS110-05 enclosure is machined from marine-grade, copper-free LM6 aluminium with a chromate conversion coating and powder-coat finish, giving an internal volume under 2 litres while achieving IP66/67 ingress protection against dust and water jets. The unit weighs approximately 4.80 kg in DC versions and 5.00 kg in AC versions, and mounts via an integral stainless-steel bracket suitable for wall, pole, or structural steelwork installation, with bracket and guard options available in A2 304 or A4 316L stainless steel for corrosive coastal and offshore environments.

Cable entry is configurable to M20, M25, 1/2 inch NPT, or 3/4 inch NPT threads, with brass, nickel-plated brass, or stainless steel entry plugs to match the site’s cabling standard and corrosion class. The horn body is manufactured from high-impact, flame-retardant UL94 V0/5VA-rated ABS in red for maximum visibility, while the beacon lens is protected by a mechanically secured, field-replaceable wire guard. Supply voltage options cover 12V, 24V, and 48V DC as well as 115V and 230V AC (50/60 Hz), and the unit operates across an ambient temperature range of -50°C to +70°C, with a tropicalised version available for continuous high-humidity service.

Key Features

The E2S BExCS110-05 combines a high-output sounder and a high-intensity beacon in one flame-proof housing to deliver dependable, code-compliant hazardous-area alarm coverage.

• Sound output up to 117 dB(A) at 1 metre across 32 selectable alarm tones with three remotely switchable volume stages.
• Xenon strobe beacon delivering 120 cd effective intensity with a 1 Hz flash rate and field-replaceable, UV-stable lenses in seven colors.
• Marine-grade, copper-free LM6 aluminium enclosure with IP66/67 ingress protection for offshore and coastal deployment.
• Certified Ex db IIB and Ex tb IIIC for Zone 1, Zone 2, Zone 21, and Zone 22 hazardous area installations.
• Automatic multi-beacon synchronisation and flip-flop alternating mode for coordinated plant-wide alarm response.
• Operating temperature range of -50°C to +70°C, with a tropicalised version for high-humidity climates.
• Flexible voltage support across 12V, 24V, and 48V DC and 115V/230V AC supplies.
• Full international certification package including ATEX, IECEx, Ex EAC, INMETRO, PESO CCOE, and UKCA approvals with SIL1 rating.

Industrial Applications

The E2S BExCS110-05 is specified wherever a hazardous-area facility needs a single, code-certified device to deliver both audible and visual alarm indication for fire, gas release, or emergency shutdown events. In upstream and offshore oil and gas installations it is fitted on platform decks, wellhead clusters, and gas compression modules; in refineries and petrochemical plants it is mounted at process units, tank farms, and loading gantries where Zone 1 and Zone 2 classifications apply. Its marine-grade construction and wide temperature range also make it a natural choice for LNG terminals, offshore support vessels, and coastal petrochemical complexes exposed to salt-laden atmospheres.

As the officially authorized partner for E2S, Seven Star LLC distributes the E2S BExCS110-05 to EPC contractors, fire and gas system integrators, and plant safety departments throughout Oman and the GCC, including projects in the Sohar and Salalah economic zones and the wider Duqm industrial development. Facility engineers designing or upgrading fire and gas alarm systems can source certified, traceable E2S alarm and beacon units locally, backed by E2S’s global engineering support and Seven Star’s regional stock and technical service, rather than waiting on long-lead imports from outside the region.
