The CHQ-ARI is a loop-powered Addressable Remote Indicator, with high-intensity LEDs and a Fresnel lens design which produces a highly visible signal. 
 
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 Sounders (CHQ-BS or YBO-BS), the Base Sounder Beacon (YBO-BSB) or the Short-Circuit Isolator Base (YBO-R/SCI).
