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*1 but only when used in accordance with the WS2-WPK instructions (2-3-0-627).
The beacon contained within the CHQ-WSB is a secondary function and therefore must not be used as a visual
alarm device to comply with EN54-23.
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/ISS7/NOV13
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 CHQWSB 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.
