Model YBO-BS(WHT) is an addressable loop powered Base Sounder 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(WHT)) or the Isolator Base (YBO-R/SCI(WHT) – 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 with the simple addition of a Cap (SI/CAP(WHT)). 

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 will operate, before automatically silencing itself, cutting noise pollution (dependant on control panel compatibility).
