ATEX Loudspeakers Zone 1 & Zone 2 Weatherproof Ex d(e) – Eaton DB4B Hazardous Area Loudspeakers Up To 25 Watts

ATEX Loudspeakers Zone 1 & Zone 2

Eaton DB4B are ATEX loudspeakers with a high power explosion proof speaker, introduced as a replacement for the DB4 with improved intelligibility and acoustic performance.

Certified for use in a wide range of temperatures (from -55ºC to +70ºC) the Ex enclosure is manufactured from GRP with a rugged thermoplastic flare providing a corrosion free and aesthetically pleasing product suitable for use in ATEX & IECEx Zone 1 and Zone 2 hazardous areas.

The frequency response of the hazardous area loudspeakers ensures that critical voice messages and general alarm tones are highly intelligible. The specific SPL figure for sensitivity is 1W @ 1m is 110dB whilst at 1m the 25W unit produces 124dB, the 15W unit 122dB and the 8W unit 119dB.

Options include DC blocking capacitors for monitored systems, resettable fuses for compliance with marine regulations and a swivel bracket that gives the installer greater flexibility when positioning the unit. The short flare option is a worthy addition to the range offering a high SPL and wide dispersion angle in a compact unit.
