Resideo 747PD Piezo Dynamic Siren, 2-Tone, Indoor, White

Built to expand indoor alarm coverage with minimal fuss, the Resideo 747PD Piezo Dynamic Siren delivers loud, reliable alerts while keeping power demands low. This 2-tone indoor siren produces up to 105 dB of sound for clear notification across homes or small commercial spaces, yet draws roughly one-quarter the current of typical sirens so you can add units to the same control panel without extra power hardware. The lightweight ABS case, hinged cover and easy-to-wire terminal block cut installation time and labor — ideal for installers working on security, surveillance and monitoring projects. Choose between Steady and Warble tones to match site requirements, and rely on an enclosed PCB and UL/CE listings for consistent field performance. Compatible with LYNX control panels and available in tampered versions to meet global requirements, the 747PD is a practical choice for contractors and integrators who need dependable, low‑power audible notification. Add the Resideo 747PD to your next alarm system deployment to broaden coverage and simplify wiring.
