- Zones 1, 2, 21, 22 - Ex d protection The Voice and Soundlip Alarms of the ETH20MDLOUD series are designed for use in potentially explosive atmospheres, in the presence of gases and dust. They guarantee a high degree of protection (IP66) to deal with binding environmental conditions, such as those found in off-shore and on-shore facilities. They are particularly responding to a connection to standard amplification systems at 100 V, for communication with the public and for connecting to alarm systems. The acoustic compression chamber is separated from the environment by a special sintering filter. They are equipped with a transformer and the sound level can be adapted and selected according to the practical requirements of the installation site.
