Model YBO-BSB2/RL is an O-rated, EN54-23 compliant, addressable loop-powered Base Sounder with integral beacon, designed to provide a 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 (YBN-R/3(SCI)) and can accommodate any device from the ESP range of sensors, beacons, or remote indicators.
The sounder can also be converted into a wall-mounted sounder beacon with the addition of a cap (SI/CAP2). The unit is rated IP21 for indoor use. An Auto-Shutdown feature allows the sounder or beacon to operate for a preset period before automatically switching off, helping to reduce noise pollution. The sounder and beacon elements can be operated independently.
