Sigcom’s SIG-3-REL is used with DAPB-100, a distributed audio power booster that provides an additional 100 watts of audio output power to any new or existing voice evacuation system. The DAPB-100 is designed to work with any manufacturer’s voice evacuation control panel including Sigcom’s VECP series. Each DAPB-100 also provides an additional four Class A or Class B 25 Vrms supervised speaker circuits with an option for 70 Vrms with addition of a supplemental transformer.
