Description

Potentially explosive areas often require the use of acoustical signals for warning, indicating or signalling purposes. The dEV20 Sounder is designed for exactly those occasions. The dEV20 is activated by turning on the supply voltage. It is designed for continuous operation and available with different operating voltages. The dEV20 Sounder consists of a pressure-resistant housing made of seawater-resistant aluminium conforming with ingress protection IP 66. Its sound conductor is made of impact-resiatnt plastics. The sounder is suitable for indoor and outdoor applications in zones 1, 2, 21 and 22. The terminal compartment is realized according to protection type “œincreased safety”. The two signalling stages can be set using a DIP switch. A selection of 32 signal tones is available for both stages. Default settings for signal tones: S0=tone 24, S1= tone 4 A signalling combination can be established using the provided stainless steel mounting plate with integrated junction box.
