HOCHIKI WALL SOUNDER & WALL SOUNDER BEACON
INSTALLATION INSTRUCTIONS
Products Covered: CHQ-WS2 / CHQ-WS2(WHT) Wall Sounders, CHQ-WSB / CHQ-WSB(WHT) Wall Sounder
Beacons, YBO-R/3(RED / YBO-R/3(WHT) Standard Bases, YBO-R/SCI(RED) / YBO-R/SCI(WHT-SNDR)
Isolator Bases.
Introduction
The CHQ-WS2 is a loop-powered addressable wall sounder. The CHQ-WSB is a loop-powered addressable wall
sounder beacon. Both units are compatible with the standard red mounting base (YBO-R/3(RED)) and the red
isolator base (YBO-R/SCI(RED)); the units have connections for both these types of base. Do not attempt to use
any other base type with these units. Both sounders and bases are also available in WHITE (see above).
Both the CHQ-WS2 and CHQ-WSB are Ingress Protection rated to IP21 for internal use, but can be made
weatherproof when used in conjunction with the WS2-WPK Weather Proofing Kit, in which case they are Ingress
Protection rated to IP65*1but only when used in accordance with the WS2-WPK instructions (2-3-0-627).
Address Setting (with Hand Held Programmer)
The units will need to be manually addressed between 1 and 127. The sounder address can be set using the Hand
Held programmer (TCH-B100) as the units both include the appropriate terminals to fit directly onto the
Programmer. See the TCH-B100 instructions for further details of address setting. The address must be set
before installation.
Tones and Volumes
Table 1 below shows the full range of sound outputs available from the CHQ-WS2 and CHQ-WSB together with
the amount of current drawn when operated. The units are also capable of utilising a number of different EN54-3
Approved tones; these are listed in Table 2, page 3. The tone of the sounder and the volume level is selected
and controlled by the control panel, therefore check with the control panel manufacturer for options and
default values available. The sounder and beacon elements of the CHQ-WSB can be controlled
independently, check with the control panel manufacturer for compatibility.

Precautions
Ensure that the unit is installed in accordance with Local Standards or Regulations.
Only use the specified Hochiki mounting bases (or WS2-WPK Weather Proofing Kit) with this wall
sounder/wall sounder beacon.
Only install in suitable environments, the following in particular should be avoided: -
Excessive ambient temperature.
Where excessive condensation or moisture is present (unless WS2-WPK is utilised).
Hazardous areas.
A high voltage tester must not be used with these units or either of the specified bases.
Ensure that the unit is securely fixed to the mounting base (and WS2-WPK if utilised).
For proper wiring supervision ensure that the cables are wired as shown in Fig 4.
Locking Mechanism
The units can be locked onto the relevant mounting base by removing a plastic lug on the underside of the
sounder, refer to Fig. 1.

2-3-0-626/ISS6/MAY11
The unit can then only be removed from the base by using a special
removal tool, TSE-SRT, which is available from Hochiki Europe
(UK) Ltd.
Installation
Both the CHQ-WS2 wall sounder and the CHQ-WSB Wall Sounder
Beacon are designed to be mounted directly onto the Red Standard
Mounting Base (YBO-R/3(RED)) or the Red Short-Circuit Isolator
Mounting Base (YBO-R/SCI(RED)) in the same method as a Sensor
(see Fig. 2). The terminals on the mounting base hold the units in
place.
Remove tab carefully using a pair of pliers.
Fig. 1
Fix the mounting base to the required surface using appropriate
fixings. For correct wiring of the each base type, refer to Fig. 4.
When installing either of these units in exterior locations use the
WS2-WPK Weather Proofing Kit. The kit consists of a
weatherproof back box and two gaskets, which must be used in
conjunction with either mounting base to maintain the IP rating
(see Fig. 3). For further information, refer to the WS2-WPK
Weather Proofing Kit instructions (2-3-0-627).
Wiring
Please refer to Fig. 4 for wiring the Red Standard Mounting Base
(YBO-R/3(RED)) and the Red Short-Circuit Isolator Mounting Base
(YBO-R/SCI(RED)):

If a control panel has not
implemented the CHQ-WSB then
it will be recognised as a YBO-
BSB. The table below shows the
volume level set as a YBO-BSB
and the corresponding level that
is set on the CHQ-WSB by any
panel configuration software that
recognises the CHQ-WSB as a
YBO-BSB.
For example, if 55dB(A) is
selected on the panel for a YBO-
BSB, the actual volume of the
CHQ-WSB will set to 90dB(A).
* Note that this is sounder current only. If
the Beacon is operating please add 5mA to
this value.
These differences in current should be
taken into consideration when calculating
total loop loading.
