ATEX Sounders Zone 1 & Zone 2
Eaton MEDC dEV 20 are ATEX sounders offering both of these signalling features and is designed for continuous operation. Hazardous areas often require the use of acoustical signals for warning or information purposes.
The ExII-sounder dEV20 has an ingress protection rating of IP66, meaning it is suitable for both indoor and outdoor installation in ATEX & IECEx Zone 1 and Zone 2 hazardous areas.
The hazardous area sounders consist of a flame-proof housing manufactured from a light grade aluminium alloy and a sound channel made from impact-resistant polyester.
The ATEX sounder dEV20 includes two signal levels. The signal tone for the first level is adjusted with the slide switches 1-5 (S0) according to the signal choice list. The signal tone for the second signal level is adjusted with the slide switches 6-10 (S1).
