Siemens ABHW-4S Audible Base P/n:101353577

The Siemens ABHW-4S Audible Base from Siemens Industry Inc. is an intelligent, supervised detector base designed for use in sleeping areas of a building. Each Model ABHW-4S base generates a 520 Hz square-wave audio signal, complying with NFPA 72 Standard, as well as UL / ULC Listed applications.

In general, Siemens ABHW-4S provides six (6) field-configurable tone patterns: two (2) volume levels are use with compatible Siemens detectors and FACPs. Steady; Temporal 3 pattern; Temporal 4 pattern; together with Temporal 4 with low-power; March Time 120, and Canadian March Time 30 are support by each intelligent audible base for sleeping areas.

Furthermore, model ABHW-4S is fully compatible with all Siemens addressable detectors listed in the detector tables included in this document. Additionally, each Model ABHW-4S base houses a pre-wired, audible sounder device, capable of generating a 520 Hz square-wave tone that produces a signal up to 85dBA at 10 ft. (3.1m) for localized annunciation.

When used in conjunction with other listed, compatible Siemens fire-safety components, Model ABHW-4S may be use in lieu of single/multiple-station smoke alarms to achieve enhanced, system-level functionality.
