SigCom SIG-70V-XFMR 70V Transformer for DAPB-100

Add 70V capability to your distributed audio power booster to support long-run speaker circuits and enterprise voice evacuation systems. The Signal Communication SIG-70V-XFMR transformer converts the DAPB-100’s standard 25 Vrms outputs to 70 Vrms, enabling reliable audio distribution for large facilities, campuses, and multi-zone security environments. Designed specifically for use with the SigCom DAPB-100 distributed audio power booster, this transformer provides a straightforward upgrade path for existing fire alarm and public address installations.

By enabling 70 Vrms speaker circuits, the SIG-70V-XFMR reduces the need for additional amplifiers and simplifies cabling for surveillance, monitoring, and mass notification systems. Installation is fast and intuitive—minimizing downtime and commissioning effort—while compatibility with UL-864 listed DAPB-100 boosters supports code-conscious deployments. US-manufactured and a direct replacement for the MNS-70V-XFMR model, this accessory is ideal for integrators specifying reliable fire alarm control panel accessories and emergency communications.
