Updates to the DB3B Sounder

Worldwide,

 – 

MEDC is pleased to announce the launch of the DB3B, a high power, explosion proof electronic sounder.

Introduced as an upgrade for the current DB3 sounder, the DB3B boasts improved functionality and performance with SPL reaching 125dB @ 1m. This significantly improves sound coverage in high noise environments, and ensures that our product will be effective in almost any application.

The launch of this unit has brought with it some exciting enhancements: it now features improved control options including negative or positive switching, and a volt-free activation option. The standard DC unit provides 3 tone stages; each stage has 28 tones available which can be independently selected.

The unit is also certified for use in temperatures from -55ºC to +70ºC (-67ºF – 158ºF).

The DB3B is ATEX, IECEx, cULus, CUTR and CQST certified, and can be purchased as part of a beacon/sounder combination unit (please contact MEDC for details). In addition, it is available as either a flameproof enclosure (Ex d), or increased safety unit (Ex de), as well as protection against Gas or Gas & Dust atmospheres, allowing for greater flexibility to suit most specifications.

Capable of producing 125dB @ 1m and with a range of pre-recorded tones, the DB3B includes an integral volume control which is ideal when a lower output is required. The unit is provided with versatile control options allowing compatibility with a wide range of control methods and PLCs. The short flare option is worthy addition to the range offering a high SPL in a compact unit.
