Simplex 4098-9771 Fire Alarm CO Detector Sounder Base - This professional-grade sounder base is engineered to provide reliable audible signaling when integrated with compatible fire alarm detection systems. - Operating voltage range of 15-32 VDC - Integrated piezoelectric sounder - Compatible with TrueAlarm analog sensors - Low-profile mounting design - Supports multiple temporal tone patterns

Building upon the legacy of previous Simplex notification accessories, this unit offers vastly improved synchronization and simplified field installation. While older modules often required complex wiring and separate power supplies, this modern iteration streamlines system deployment to meet current NFPA safety standards and life-safety requirements.

Advanced Signaling and Performance

Engineered for high-reliability environments, this sounder base utilizes sophisticated circuitry to ensure consistent performance during critical alarm events. By combining base functionality with localized audible notification, it reduces the complexity of alarm coverage in sensitive areas, providing a more efficient, code-compliant solution for modern fire protection infrastructure.
