E2S is one of the world's leading independent manufacturers of high-performance audible and visual signals for hazardous locations with potentially explosive atmospheres as well as industrial, marine and commercial applications. Combining the latest technology with engineering expertise, we have created the most extensive range of life-saving signals that satisfy the toughest global standards.
Our devices are designed for areas where concentrations of flammable gases, vapours or dusts occur. They are approved to global standards as defined by, amongst others, IECEx, ATEX, CEC and NEC. E2S offers a five-year global product warranty as standard.
Our head office, manufacturing operations and customer service centre are based in London, UK. We have a dedicated distribution hub offering local inventory and technical support in Houston, Texas, US. Together with our system integrator and distribution partners around the world, we will help you devise the perfect audible and visual signalling solution for your application.
Intrinsically safe audible and visual signals and manual call points
The IS range includes intrinsically safe sounders, beacons, combination units, manual call points and panel mount status lights and buzzers. These products are ideal for group II Zone 0, and the mini alarm is also suitable for group I mining uses.
The range features compact devices that can be powered from one barrier or isolator and multi-device systems featuring automatic synchronisation. Many of the alarm sounders come with an alarm accept function where the operator silences the alarm for set periods. The alarm horns are CPR compliant, EN54 part 3 tested and VDS approved.
Explosion and flame-proof alarm horn sounders, warning beacons and manual call points
The BEx range includes high-output visual signals, powerful alarm horns and manual call points for use in Zones 1 and 2 gas environments and Zones 21 and 22 dust environments. Plated assemblies consisting of sounders and beacons can be provided. The range features marine-grade aluminium Ex d (IP67) and Ex de (IP66) enclosures, and many devices have multiple approvals, including IECEx, ATEX, GOST-R, INMETRO and VDS.
The GNEx range of corrosion-proof glass-reinforced polyester alarm horn sounders, PA loudspeakers and manual call points are ATEX and IECEx approved for Zones 1 and 2.
Non-sparking alarm horns and beacons
For Class I Division 2 applications, the UL approved E2x range offers high-performance Xenon beacons, high-powered alarm horns and combination devices. The alarm horn sounders provide 45 alarm tones and three stages suitable for all signalling duties. The PA loudspeakers are rated to 15W and 25W and come in line transformer and low-impedance versions. The enclosures are manufactured from lightweight corrosion-free PPS and impact-resistant ABS with enclosures that are NEMA 4, 4X and 13 rated.
Heavy duty alarm horns and Xenon beacons
For heavy duty and marine applications, the M series provides powerful alarm horn sounders, PA loudspeakers and combination devices in IP66/67 rate enclosures. The high output alarm sounders are suitable for environments with high ambient noise levels. Xenon beacons are available in 5J and 10J models.
Wide area and disaster warning signals
Where larger coverage distances are required, E2S offers wide area and disaster warning siren systems that can be used for evacuation or emergency warnings. The systems are ideally suited for installations that need battery back-up. They can also be supplied with full telemetry systems.
Fire voice alarm systems
A vast range of fire and industrial signals are available as Appello voice alarm products for applications such as fire, security, marine and heavy duty environments. The products come in a variety of materials and they can store up to two minutes of user-recordable content, which can be played with or without an alarm tone.
All product specifications, data sheet downloads, drawings, images, CAD drawings and approvals information is available from the E2S website.
