Kidde FX-T3T4 Tone Generator for Detector Sounder Bases with CO mode

Deliver reliable, code-compliant audible signaling for fire and carbon monoxide events with the Kidde Commercial FX-T3T4 tone generator. This addressable tone generator is designed for seamless integration with compatible detector sounder bases (including the GSA-SBT), producing the required T3 (fire) and T4 (CO) temporal patterns to meet NFPA 72 and NFPA 720 standards. Because the FX-T3T4 uses two addresses on the signaling line circuit (SLC), it provides flexible system mapping and simplifies diagnostics for technicians working on commercial fire, security and CO monitoring installations. The module’s addressable functionality reduces installation time and wiring complexity while ensuring consistent audible notifications across your building’s monitoring and surveillance systems. Ideal for building owners, integrators and service teams, the FX-T3T4 improves occupant safety and regulatory compliance without adding operational overhead. Add the Kidde FX-T3T4 to your next fire or gas detection project to streamline testing and maintain reliable alarm signaling—contact your distributor or order now to enhance your security and monitoring setup.
