Hochiki CHQ-WS2(WHT) Addressable Wall Sounder - White Case

The Hochiki CHQ-WS2(WHT) is an addressable, loop-powered wall sounder in a white case for the Hochiki ESP analogue addressable system. It offers 51 tones and 8 volume levels with a maximum output of 102 dB(A) (±2 dB(A)) at low current consumption, and fits the Hochiki wall sounder standard base or isolator base (sold separately). It is rated IP21 for internal use and can be made weatherproof (IP65) with the Hochiki weatherproof kit. An auto-shutdown mode can silence the sounder after a set time (panel dependent).
