ATEX Call Points Zone 1 & Zone 2 Safe Break Glass Hazardous Area Ex ed, Ex ia – Eaton MEDC BG Hazardous Area Manual Call Point

Eaton MEDC BG are manual fire alarm ATEX call points designed for use in flammable atmospheres and harsh environmental conditions in ATEX Zone 1 and Zone 2 hazardous areas.

The GRP enclosure of the hazardous area call points are suitable for use offshore or onshore where light weight combined with a high level of corrosion resistance is required.

The break glass of the ATEX call point is covered by a membrane which protects the operator from glass fragments meaning that no hammer is required to activate the unit.

A plastic ‘break glass’ or deformable operating element is available to replace the break glass. Once the flexible element is pressed it will bend but will not break.

The hazardous area call point is reset by repositioning the element.

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
