Honeywell SD365T Addressable Photoelectric Smoke Heat Detector

The Fire-Lite SD365T is an addressable combination photoelectric smoke and heat detector designed for commercial and institutional fire alarm systems. As an addressed device, it communicates its precise location directly to a compatible Fire-Lite control panel, enabling faster alarm verification and streamlined system diagnostics. The dual-sensing technology combines photoelectric smoke detection with thermal sensing, providing a layered approach to early fire detection that helps reduce nuisance alarms while improving response to a broad range of fire signatures. Engineered for professional life-safety installations, the SD365T is suited for offices, schools, healthcare facilities, hospitality environments, and other commercial occupancies where code-compliant, addressable fire detection is required.

Key features & benefits

• Combination Photoelectric and Heat Detection — Integrates two detection technologies in a single device, allowing the unit to respond to both slow-smoldering fires and rapid temperature rise events for broader fire-signature coverage.
• Addressable Architecture — Each detector carries a discrete address on the signaling line circuit, giving the fire alarm control panel exact point-of-detection identification to accelerate emergency response and simplify maintenance troubleshooting.
• Fire-Lite Ecosystem Integration — Designed as a genuine Fire-Lite component, the SD365T is built to work within Fire-Lite addressable fire alarm system infrastructures, supporting consistent system performance and simplified panel configuration.
• Commercial Life-Safety Grade Construction — Built to the standards expected of professional fire alarm installations, making it appropriate for a wide range of commercial, institutional, and industrial occupancies requiring reliable, code-driven detection.
