The Hochiki YBO-BSB2(WHT)/WL is an addressable, loop-powered base sounder with an integral beacon (VAD), in a white case with white LEDs, for the Hochiki ESP analogue addressable system. It gives a choice of 51 tones and a range of volumes up to 98 dB(A) (±2 dB(A)), and its beacon is 'O' rated to EN 54-23. It fits the standard base (YBN-R/3) or isolator base (YBN-R/3(SCI)) and can carry any ESP sensor, beacon or remote indicator; with an SI/CAP2 cap fitted it becomes a wall sounder beacon. It is rated IP21 for internal use.
