MEDC DB3B high power explosion-proof Sounder

The MEDC DB3B is a high power explosion-proof Sounder that is produced as a replacement for the MEDC DB3 Sounder. This MEDC Sounder has improved functionality and performance over the DB3.

The MEDC DB3B has an EX enclosure that is produced from GRP with a rugged thermoplastic flare that provides a corrosion-free product that is certified to be used in a wide range of temperatures from -55°C up to +70°C. Capable of producing 122dB @ 1m and with a range of pre-recorded tones, this Sounder includes an integral volume control which is ideal when a lower output is required.

This MEDC Sounder proves its versatility by additionally being able to work with a common positive supply and switching the negatives. The tone stages of the DB3B can also be controlled via voltage free contacts provided by a Control Panel.
