ATEX signal horn dMS series - 32 tones, for zone 1 and 21
The explosionproof dMS horn has an aluminium housing with a glass fibre reinforced polyester sound shield and no fewer than 32 different tones. The device can deliver a volume of between 85 and 115 dBA, configurable in 4 levels. The diversity of signals increases the usability and reduces the chance of confusion with other signalling devices.
This sound horn is suitable for use in zones 1, 2, 21 and 22. In combination with a housing made of seawater-resistant aluminium and an IP66 protection rating, this makes the device ideal for a wide range of environments.
Moreover, the dMS sound horn has a very compact design compared to the classic signal horn.
