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.
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).
