The Hochiki CHQ-WSB2/WL is an addressable, loop-powered wall sounder with an integral visual alarm device (VAD) beacon, in a red case with white LEDs, for the Hochiki ESP analogue addressable fire alarm system. The beacon sits in the horn and uses high-intensity LEDs; it is ‘O’ rated to EN54-23. This unit is supplied without a base: fit it to a YBO-R/3(RED) standard sounder base or a YBO-R/SCI(RED) isolator base, sold separately.
