Explosion proof acoustic signallers suitable for hazardous area Zone 2 & Zone 1

Ex db /tb – IP66

The acoustic signallers ETS 60 are specific for potentially explosive atmospheres (chemical plants and refineries, pumping stations, painting plants, silos and movement of wheat) and/or anywhere there may be the presence of dust. The particularly limited dimensions and the possibility of fastening by bracket in four different positions (at 90° along the longitudinal axis) allow the maximum installation flexibility. They work in intermittent duty S3 ON 1 min – 10 min OFF, according to EN 60034-1.

Protecting cage is included. The external screws are in Stainless Steel AISI 304.

Acoustic signallers (siren) series ETS 60 114, usefull where there is a significant background noise due to their strong power, are also available.
