The LE-ASB Analog Sounder Base is designed for use with Lifeco analog style sensors models LE-ALG-V, LE-ALK-V, LE-ALK-V2 LE-AIE-EA, and LE-ATG-EA. Each addressable base is to be connected to a Lifeco dCP Signaling Line Circuit (SLC). The LE-ASB provides an audible alarm in the immediate vicinity. Typical applications are use in hotels, apartments, and hospitals. The LEASB has a highly configurable programming algorithm that allows the user to setup 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.
