Alarm sounders EX ATEX

The universal alarm sounders fulfil the basic requirements of the ATEX Directive (94/9/EC) and have been approved for use in zones 1 and 2, as well as 21 and 22 explosion hazard zones (depending on the version). They are intended for operation in heavy-duty conditions on land and at sea.

Thanks to reversed polarisation or connection to a second power source DB1P and DB1HP sounders may be switched between two pitches. They are highly efficient, particularly in loud noise conditions. The membrane, the flare and the main part are fully made of glass reinforced polyester resistant to UV light. Bolts and joints are made of stainless steel. The conical membrane prevents wave accumulation. Optionally, the terminal chamber in ex-rating is available.

Optional ex-rated
terminal chamber
IP66/IP67 protection class
Certified operating temperatures between -55°C and +70°C
Made of anti-corrosive glass reinforced polyester
Capacity up to 118 dBA
