The CHQ-AB(AMB) is an addressable loop-powered Beacon, with high-intensity LEDs and a Fresnel lens design which produces a highly visible flash. The casing exactly matches the Hochiki ESP Sensor range in shape and colour providing seamless integration. The unit can be used on the standard ESP Base (YBN-R/3), the Base Sounder (YBO-BS), the Base Sounder Beacon (YBO-BSB) or the Short-Circuit Isolator Base (YBO-R/SCI).
