Model YBO-BSB(WHT) is an addressable loop powered Base Sounder with integral Beacon, innovatively designed to give a range of tones and volumes with a maximum output of up to 98 dB(A) (±2 dB(A)) with low current consumption.  The unit is designed to fit to the Standard Base (YBN-R/3) or the Isolator Base (YBO-R/SCI – from Batch Number 6044) and can be fitted with any of the white ESP Range of Sensors, Beacons or Remote Indicators. 

The unit can also be converted into a wall sounder beacon with the simple addition of a Cap (SI/CAP).  The sounder is Ingress Protection rated to IP21 and for internal use only.  An Auto-Shutdown feature allows the user to set a fixed time within which the sounder or beacon will operate, before automatically shutting down, cutting noise pollution in the case of the sounder element*.  Sounder and Beacon elements can be operated independently from each other*. 

*Dependent on control panel compatibility.
