Overview Features Technical Data Downloads & Resources

The Hochiki CHQ-WS2(WHT) is an addressable, loop-powered wall sounder designed for reliable audible warning in fire alarm systems.

Delivering a variable sound output from 90 to 102 dB(A) at 1 metre, it provides high performance with low current consumption.

This unit can be mounted to either the Hochiki Standard Base (YBO-R/3(WHT)) or Isolator Base (YBO-R/SCI(WHT/SNDR)) for flexible installation.

Rated IP21 for indoor use, it can also be upgraded for outdoor environments using the optional WS2-WPK(WHT) Weatherproof Kit, which includes a back box and gasket set.

An auto-shutdown feature allows a fixed operation time before the sounder automatically silences, helping to reduce unnecessary noise.

With 51 user-selectable tones, all EN54-3 compliant, this sounder offers adaptability across multiple applications.
