Summary
The Hochiki CHQ-WSB2 is an addressable wall sounder beacon that combines audible and visual fire warning in one device, with 51 user-selectable tones giving you far more scope to match the sound profile to the building than a fixed-tone unit allows. It’s a single loop address device, commissioned via the TCH-B200 Hand Held Programmer, and fits either the Hochiki standard base or isolator base you may already have on site.

That tone flexibility, combined with independent control of the sounder and beacon, means you can tailor warning behaviour zone by zone without specifying multiple product variants. On a mixed-use site you might run full audible and visual alarm in common areas but keep the beacon active and the sounder silenced overnight, all from the same device.
An auto-shutdown function lets you set a fixed sounding period before the unit silences itself automatically, which helps manage noise complaints on sites with prolonged or repeated alarm testing. Low quiescent and sounding current also makes it straightforward to budget loop capacity when you’re populating larger systems.
Features
- 51 user-selectable tones – match the alarm sound to the building type or zone without swapping devices
- Independent sounder and beacon operation – run audible and visual warning separately, useful for night mode or phased evacuation strategies
- Auto-shutdown mode – set a fixed sounding time so the unit silences itself automatically, reducing nuisance noise on site
- Variable sound output 90-102 dB(A) – adjust volume at 1 metre to suit the space instead of specifying a different model
- Selectable 0.5 or 1Hz flash frequency – set the beacon flash rate to match zone requirements
- Low current consumption – quiescent draw as low as 150 μA helps you fit more devices on a single loop
- Fits Hochiki standard or isolator base – reuse existing base stock and simplify replacement on upgrade jobs
- Weatherproof kit available (WS2-WPK) – upgrade from IP21 to IP65 for exposed or semi-outdoor mounting positions
- EN54-3 approved tones and EN54-23 ‘O’ rated beacon – compliant for use on EN54 fire alarm systems

FAQ
It fits the Hochiki standard base (CHQ-WPK and YBO-R/SCI) or the isolator base (YBO-R/SCI(RED) and YBO-R/SCI(WHT)). If you’re retrofitting onto an existing loop, check which base type is already installed before ordering. The CHQ-WSB2 is a single loop address device, programmed using the Hochiki TCH-B200 Hand Held Programmer. The programmer is also used to select which of the 51 tones and which flash frequency (0.5 or 1Hz) the device will use. As standard the unit is IP21 rated, which is for internal use only. For semi-outdoor or exposed positions, the WS2-WPK weatherproof kit (a specialised back box and gasket set) raises this to IP65. Yes, the sounder and beacon can be operated independently, so you can configure a zone to flash without sounding, or sound without flashing, depending on the application. Quiescent current is 150 μA with a standard base or 200 μA with an isolator base. Sounding current ranges from 2 mA at 90 dB(A) up to 8 mA at 102 dB(A), with an additional 7 mA when the beacon is active, so include these figures when calculating total loop load. The datasheet confirms a SIL Level 2 approved variant is available, but doesn’t give a separate part number here. Confirm the correct ordering code for a SIL-rated application directly with the manufacturer or Huvo before specifying.Which bases does the CHQ-WSB2 fit?
