Model CHQ-WSB2/SIL is an addressable loop powered Wall Sounder Beacon innovatively designed to provide a range of tones and volumes with a maximum output of up to 102dB(A) (±2dB(A)) with low current consumption. The unit features an integral beacon within the horn utilising high intensity LED technology and is designed to fit to the Standard Wall Sounder Base (YBO-R/3(RED)) & YBO-R/3(WHT)). The sounder is IP rated to IP21 for internal use but it can be made weatherproof (IP65) by utilising the CHQ-WPK Weatherproof Kit, which consists of a specialised back box and gasket set.
