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).
