The DB3B is a high-power explosion-proof sounder, introduced as a replacement for the current DB3 with improved functionality and performance.

Certified for use in a wide range of temperatures from -55ºC to + 70ºC, the Ex housing is manufactured in GRP with a robust thermoplastic flare offering a product without corrosion and aesthetics.

Capable of producing 125dB @ 1m and with a range of pre-recorded sounds, the DB3B includes an ideal full volume control for lower output.

The unit has versatile control options for compatibility with a wide range of control methods and controllers.

The standard DC unit has 3 tone levels, each floor has 28 tones that can be independently selected.

The unit can be controlled by reversing the polarity of the power supply (2 stages) or by providing a common negative and switching between several positive power supplies.

The DB3B proves its versatility by being able to work with a common positive power supply and switching the negatives.

The tone stages of the DB3B can also be controlled via voltage-free contacts provided by a control panel.

The flexibility of the range continues with a wide range of supply voltages. The short flare option is an interesting addition to the range offering a high SPL in a compact unit
