DB3B sounders range up to 122dB
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 -55°C to +70°C the Ex enclosure is manufactured from GRP with a rugged thermoplastic flare providing a corrosion free and aesthetically pleasing product.
Capable of producing 122dB @ 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.
