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
Call Point Order Code MEDC BG3.
♦ 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.
The following code is designed to help in selection of the correct MEDC hazardous area call point with ATEX approval and certification. Build up the part number of the call point by inserting the code for each component into the appropriate box.
MEDC have developed ATEX & IECEx call points designed for harsh and hazardous area conditions and where there is a risk of explosion due to the presence of flammable atmospheres both onshore and offshore – since 1975 MEDC have been designers and manufacturers of Explosion Proof alarm, signal, control and communications equipment.
