CHQ-WS2 is an addressable loop-powered wall siren innovatively designed to provide a range of tones and volumes with a maximum output of up to 102 dB(A) (±2 dB(A)) with low current consumption.

It is designed to fit the standard (YBO-R/3(RED)) or isolator base (YBO-R/SCI(RED)).

Rated IP21 for indoor use, but can be made weatherproof using the WS2-WPK, kit consisting of a watertight back box and gasket kit.

It also incorporates an automatic shut-off mode* that allows the user to set a fixed time within which the siren will operate before automatically silencing, ideal for minimizing noise pollution.
