Analogue Wall Sounder


CHQ-WS2 is an addressable loop-powered Wall Sounder 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 is designed to fit the Standard Base (YBO-R/3(RED)) or the Isolator Base (YBO-R/SCI(RED)). The sounder is IP rated to IP21 for internal use but it can be made weatherproof by utilizing the WS2-WPK Weatherproof Kit, which consists of a specialized back box and gasket set.

Also incorporates an auto-shutdown mode* which allows the user to set a fixed time within which the sounder will operate, before automatically silencing itself, ideal for minimizing noise pollution.
