17 February 2015

E2S Warning Signals, established some 25 years ago, is the world's leading independent manufacturer of high performance audible and visual signals for commercial, industrial, marine and hazardous locations producing over 250,000 units per year across more than 190 different products. 

Combining the latest technology with industrial design, engineering and manufacturing expertise E2S has created the most extensive range of life saving signals that satisfy the toughest global standards.

The head office and manufacturing operations are located in London, UK. A dedicated distribution hub and sales operation is based in Houston, Texas principally serving North and South American customers as well as supporting projects globally. An international network of distribution partners and system integrators ensure worldwide product availability and local technical support.

Global approvals ensure that E2S products can be specified for use in projects around the world. Approvals held on various products include ATEX, IECEx, cULs, FM, TR CU, VdS, INMETRO, MED and CE.

To help specifiers choose the most appropriate warning indicator for the application, a wealth of reference information is freely available at e2s.com/information.

Product Overviews cover Hazardous area signalling , Fire & industrial signalling and Wide area signalling.

Product Advice covers interface selection of intrinsically safe sounders and beacons, guide to audible signals, guide to visual signals, guide to alarm stage selection and gives the opportunity to listen to and download E2S alarm horn sounder tones.

General references and guidelines cover IP (Ingress Protection) ratings, dB ratings, PFEER/UKOOA alarm tone guidelines and sound basics: measuring power in dB.

Hazardous areas applications

Hazardous areas are to be found in a very wide range of manufacturing industries, far beyond the obvious petrochemical plants. Food, pharmaceutical and cosmetic manufacture all involve processing potentially explosive substances, while the problems of explosions in grain silos and sugar processing plants are very well documented. Hazardous areas are defined as areas where concentrations of flammable gases, vapours or dusts may occur, either constantly (Zones 0 and 20), under normal operating conditions (Zones 1 and 21) or unusually (Zones 2 and 22). Additional conditions relating to the temperature classification and the auto-ignition temperatures of the type of gas or dust to be found.

Guides on the web site covering hazardous area provide much general information

Fire and industrial signalling

In the great majority of automatic fire alarm sounders or fire alarm systems, the end result of the detection of a fire is the initiation of audible and visual warning devices that alert the occupants to the danger so that they can evacuate the premises. EN54-23 is the European product standard for visible warning devices used in fire systems; the L101 beacon is approved for use in Wall mount, Ceiling mount and Open classes. Combination strobe/sounder units are also approved.

Given the complexity and variation of different types of buildings and structures in which fire alarm sounders are installed, and the further variations to be found in the homogeneity or otherwise of the occupants, it is clear that, for maximum effectiveness, many different types of fire alarm sounders will be required. For example, at one end of the spectrum may be an offshore oil rig, which is manned by highly trained workers who operate under strict safety procedures at all times; at the other end is a large retail development crowded with shoppers who are unfamiliar with the general layout of the building or the position of the nearest emergency exit. 

Clearly, the technical requirements for a fire alarm system and the nature of the warning signals themselves will vary greatly. The key consideration for the system designer is how to produce clear, unambiguous fire alarm warning devices throughout the protected areas in the event of an emergency.
