The Hochiki CHQ-AB(BLU) is an addressable, loop-powered visual indicator (beacon) with an ivory case and blue lens for Hochiki ESP intelligent fire alarm systems. High-intensity LEDs and a Fresnel lens produce a highly visible flash, and the casing matches the ESP sensor range in shape and colour. It fits the standard ESP base (YBN-R/3), the YBO-BS base sounder, the YBO-BSB base sounder beacon or the YBO-R/SCI isolator base. This beacon is not EN 54-23 compliant.
