The ASB Analog Sounder Base is designed for use with Hochiki analog sensors ALG-V, ALK-V, ACA-V, AIE-EA, and ATG-EA. Each addressable base is to be connected to a Hochiki America Corporation DCP Signaling Line Circuit (SLC). The ASB provides an audible alarm in the immediate vicinity. Typical applications are hotels, apartments, and hospitals. The ASB has a highly configurable programming algorithm that allows the user to set up groups of bases for synchronization of modulation tones. Each device has 16 states that are programmed with the desired output pattern to be used (e.g., “Temporal” or “March”) for each state.
