The BR385 is a third generation intrinsically safe field mounting sounder. It produces a loud audible warning signal in a hazardous area and 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, Australian and Singaporean defined warning, alert and evacuation tones.
The BR385 sounder can be used with the BA386 beacon to form a combined audio visual alarm in which the sounder may be silenced for a predetermined time by an external ‘alarm accept’ contact, but may only be used for ATEX systems. The BA386 beacon includes terminals to power the sounder, and for an external push button to silence the sounder. The silence time is adjustable from 1 to 30 minutes. A free combining kit to join the two units is an available option when ordering the BR385 and BA386 on the same order.
Supported by a three year guarantee.
