Hochiki Fire Alarm Sounder Beacon, White Case, White LEDs CHQ-WSB2(WHT)/WL
About this product
The Hochiki CHQ-WSB2(WHT)/WL is a fire alarm sounder beacon for addressable loop systems, combining sound and light in one wall unit. It suits indoor positions where people need to hear and see the alarm. It has a white case, white LEDs and output of up to 102dB(A), with an O rated beacon.
Key features
- One loop device for sound and light – an integral beacon within the horn
- Volume to suit the area – 90 ~ 102 dB(A) (±2 dB(A)) at 1 metre
- A tone to suit the site – 51 user-selectable tones, all EN54-3 approved
- Standards-rated light – O' Rated Beacon to EN54-23
- Blends with pale walls – white case with white LEDs
For installers
- Power: loop powered, 17 ~ 41 Vdc. Sounding current 2 mA to 8 mA, plus 7 mA with the beacon active.
- Mounting: base fixing centres 48 ~ 74 mm. Size H112 x W112 x D67 mm, 164 g. Address it first, between 1 and 127, using the hand-held programmer TCH-B200.
- Compatibility: compatible bases are YBN-R/3(WHT)-SCI, YBO-R/3(RED), YBO-R/3(WHT) and YBO-R/SCI(RED). Do not use any other base type.
- Standards: beacon O rated to EN54-23, tones EN54-3 approved. IP21 for internal use.
Frequently asked questions
What does WL mean in the code?
White LEDs. The bracketed WHT marks the white case, so this one has a white case and white LEDs.
Can it go outdoors?
Not as it comes. It is IP21 for internal use, and needs Hochiki's weather proofing kit outside. That gives IP65 when fitted to the kit's instructions, though LPCB approval only reaches IP33C.
Which base does it fit?
YBO-R/3(WHT) is the white standard base. YBN-R/3(WHT)-SCI, YBO-R/3(RED) and YBO-R/SCI(RED) are also compatible. Do not use any other type.
How is the address set?
With the TCH-B200 hand-held programmer, before installation. Use an address between 1 and 127.
How much current does it draw?
Typically 150 μA at rest on a YBO-R/3(WHT) base. With sounder and beacon both active it draws 9.0 mA at 90 dB(A), rising to 15.0 mA at 102 dB(A).
Will an older panel recognise it?
Usually, but perhaps under another name. A panel that has not implemented it will see a YBO-BSB2, and the volume levels then shift, so 55dB(A) selected becomes 90dB(A) actual.
