SDi BTB65 Bedrock TalkBox

Ensure fast, reliable voice alarm and intelligibility testing with the SDi Fire BTB65 Bedrock TalkBox acoustic signal source. Built for commissioning and maintenance teams, the TalkBox provides a calibrated STIPA and test-tone generator so you can verify voice evacuation systems, fire alarm audibility, and compliance with confidence. The unit’s loudspeaker covers a wide frequency range (20–15,000 Hz) and plays back signals at a standardized 54–72 dB(A) at 1 m, enabling repeatable measurements for audit-ready reporting. Use the line-out to feed test signals into external amplifiers or PA systems, or operate directly from the integrated speaker for quick on-site checks. An easy-to-use touch screen and adjustable signal level speed up testing workflows and reduce technician training time. Rugged and portable, the TalkBox is powered by the included external supply for dependable field performance across security, surveillance, and monitoring projects.
