Fire safety sounder, speaker, strobe

Block diagram

Overview

Our integrated circuits and reference designs help you create an advanced fire safety sounder, speaker and strobe notification system that reduces overall size and cost while meeting fire protection code standards.

Design requirements

Fire safety sounder, speaker and strobe designs often require:

  • Pre-recorded speech audible notifications that meet sound pressure level and frequency requirements.
  • A single solution that can generate multiple audible notification frequencies and intelligible audio.
  • Generating high-intensity strobes without increasing voltage sag.
