The ABHW-4B is a Siemens audible detector base for use in sleeping areas within residential and hotel-type occupancies. NFPA 72 requires low-frequency or temporal-pattern audible signals for sleeping area notification to achieve effective occupant arousal. The ABHW-4B integrates with Siemens addressable detector heads on the Cerberus PRO and Desigo Fire Safety platforms, providing built-in sounder capability without a separate notification appliance at each sleeping room detector location.
