MEDC SM87PB

MEDC SM87PB 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.

Intrinsically Safe Ex ia and Flameproof Ex d versions of each call point are available for safely raising the alarm in potentially explosive atmospheres including ATEX & IECEx Zone 1 and Zone 2 hazardous areas. Both the Ex ia units and the Ex d versions of the MEDC SM87PG call point have the same external appearance.

The internal components are identical throughout the range. Each unit can be wired for either NO, NC or CO contacts to customer specification

A choice of either stainless steel or alloy makes the ATEX call point range suitable for either the offshore or onshore industries. Stainless steel is one of the most durable materials available on the market and is both hard wearing and corrosion resistant. This increases the life of products in harsh environments and therefore reduces maintenance costs.

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)
