MEDC SM87BG Call Point

MEDC BG3 are ATEX call points designed for use in the most arduous environmental conditions. The hazardous area call points, manufactured by MEDC, are manually operated fire alarms that are both simple to install and maintain in explosive atmospheres in onshore or offshore locations in accordance with the ATEX & IECEx certification and explosion protection levels.

The hazardous area call points are manufactured from glass reinforced polyester (GRP) which provides a robust, corrosion free construction and ensures effective and reliable operation in harsh industrial and offshore environments in ATEX Zone 1 and Zone 2 hazardous areas

ATEX call points are supplied in natural red GRP or painted to customer specification. ‘Burning House’ duty label is provided as standard, other duty and tag labels may be supplied to customer specification.

The Eaton MEDC BG range of Zone 1 & Zone 2 call point caters for numerous options such as variety of colours, LED indication, earth continuity, double switch, etc

Hazardous Area Guide

♦ Definition : Potentially explosive atmospheres exist where there is a risk of explosion due to mixtures of gas/air, vapour/air, dust/air or other flammable combinations. Where electrical equipment has to be used in these areas, it must be so designed and constructed such that it does not create sources of ignition capable of igniting these mixtures.
♦ Area Classification : Process plants are divided into Zones (European and IEC method) or Divisions (North American method) according to the likelihood of a potentially explosive atmosphere being present. Note: North American legislation now allows Zones to be used to classify areas, where this practice is used it follows the IEC Zone method.

➡ For further information about see Hazardous Area Zones and T-Class Temperature Ratings.

European ATEX & IEC ClassificationDefinition of Zone or DivisionNorth American Classification
Zone 0 (gases)A hazardous area in which an explosive mixture is continuously present or present for long periodsClass I Division I (gases)
Zone 20 (dusts)Class II Division 1 (dusts)
Zone 1 (gases)A hazardous area in which an explosive mixture is likely to occur in normal operationClass I Division 1 (gases)
Zone 21 (dusts)Class II Division 1 (dusts)
Zone 2 (gases)A hazardous area in which an explosive mixture is not likely to occur in normal operation and if it occurs it will exist only for a short timeClass I Division 2 (gases)
Class II Division 2 (dusts)
Zone 22 (dusts)Class III Division 1 (fibres)
Class III Division 2 (fibres)
