MEDC FB4 / FL4 | ATEX Beacons

Zone 1 & Zone 2 Hazardous Areas

MEDC FB4 & FL4 are ATEX beacons specifically designed for use in potentially explosive atmospheres and harsh environmental conditions in ATEX & IECEx Zone 1 and Zone 2 hazardous areas.

The marine grade alloy or stainless steel enclosures of the ATEX beacons are suitable for use offshore or onshore, where lightweight combined with corrosion resistance and strength is required, and can be ordered from Thorne & Derrick with MEDC call points for integration into fire detection systems in the explosive atmosphere industries.

The hazardous area beacons can be painted to customer specification and fitted with identification labels.

The MEDC FB4 & FL4 are available with optional Exe terminal chamber.

Contact Thorne & Derrick for customer service, competitive quotations and availability from stock for the MEDC range of sounders, including MEDC LD15, for safe use in hazardous areas with explosive atmospheres.
