BR385 - BA386

Intrinsically Safe Sounder Beacon Combination

• Intrinsically Safe
• ATEX II 1G EEx ia IIC T4
• Operating Temp. Range -20°C to + 60°C
• IP56

The BR385 is a third generation intrinsically safe field mounting sounder which supersedes the BA385-IIC and BA385-IIB. The new sounder, which produces a loud audible warning signal in a hazardous area has forty nine different first stage alarm sounds selectable by internal switches. Each first stage tone can be changed to a second or a third stage alarm sound by an external contact which may be in the safe or hazardous area. Selectable outputs include DIN, NFS, PFEER

The BA386 beacon is significantly less expensive than the traditional Xenon devices, although it has a similar light output, flashes more frequently and is available in three different colours.

The high efficiency of the BA386 enables the beacon and the sounder to be powered from a common Zener barrier or galvanic isolator. In combined systems this eliminates one barrier or isolator and associated wiring, thus simplifying the installation and further reducing costs.
