Model YBO-BS is an addressable, loop-powered Base Sounder designed to deliver a wide range of tones and adjustable volumes, with a maximum output of 98 dB(A) ±2 dB(A) and low current consumption. The unit is compatible with the Standard Base (YBN-R/3) or the Isolator Base (YBO-R/SCI – from Batch No. 6044) and can be fitted with any device from the ESP range of sensors, beacons, or remote indicators.
The YBO-BS can also be converted into a wall sounder by adding a simple cap (SI/CAP). The unit is rated IP21 for internal use.
An Auto-Shutdown feature allows the sounder to operate for a user-defined period before automatically silencing, helping to reduce noise pollution (dependent on control panel compatibility).
