SigCom DAPB-100 Distributed Audio Power Booster for Voice Evacuation System, 100W

The Signal Communication DAPB-100 distributed audio power booster delivers a fast, cost-effective way to expand voice evacuation capacity and improve life-safety coverage. Designed for use with any manufacturer's voice evacuation control panel — including SigCom VECP series — the DAPB-100 adds 100 watts of Class D digital audio power and four fully supervised speaker circuits (Class A or B) without replacing your existing system. With native 25 Vrms support (70 Vrms optional), an integrated UL-listed power supply and battery charger, and UL 864 / UL 1711 listings, this booster provides code-compliant reliability for fire alarm, emergency notification and building security/monitoring applications. Activation is simple via a 24 VDC polarity-reversing NAC or dry-contact, so installers can integrate the unit quickly into campus, healthcare, education or industrial environments. Ideal for retrofits, expansions, or new installations where dependable paging, monitoring and evacuation voice clarity are required. Contact your Signal Communication distributor to specify the DAPB-100 for your next voice evacuation or fire protection project.
