Honeywell SD365 Addressable Photoelectric Smoke Detector

The Fire-Lite SD365 is a photoelectric smoke detector engineered for addressable fire alarm applications in commercial and institutional facilities. Utilizing optical detection technology, it identifies the presence of visible smoke particles that are characteristic of slow, smoldering fires, enabling early-stage warning before conditions escalate. As an addressable device, the SD365 communicates its status directly to compatible Fire-Lite fire alarm control panels, allowing system operators and monitoring personnel to pinpoint the exact detection point within a building — a critical advantage in large or complex installations. Professional fire alarm installers benefit from a device built to commercial life safety standards, offering straightforward integration into Fire-Lite addressable system architectures. The SD365 is well suited for offices, schools, healthcare facilities, hospitality environments, and other occupancies where reliable, system-integrated smoke detection is a code and operational priority.

Key features & benefits

• Photoelectric Detection Technology — Employs an optical sensing method that responds to the visible smoke particles produced by slow-burning, smoldering fires, supporting early detection before flames develop fully.
• Addressable System Integration — Designed to work within Fire-Lite addressable fire alarm systems, enabling the control panel to identify and report the precise location of an alarm or supervisory event for faster response.
• Point-Level Identification — Each detector communicates its individual status to the panel, eliminating the ambiguity of conventional zone-based systems and streamlining troubleshooting and maintenance for installers and facility operators.
• Commercial Life Safety Construction — Built to the quality standards expected in professional fire alarm installations, making it appropriate for commercial, institutional, and light industrial environments where code compliance and reliability are essential.
• Broad Application Suitability — Fits naturally into a wide range of occupancy types including offices, schools, healthcare facilities, and hospitality properties where addressable detection infrastructure is already in place or being newly deployed.
• Simplified Maintenance and Diagnostics — The addressable architecture supports ongoing system health monitoring, allowing technicians to quickly identify devices that require attention without manual point-by-point inspection across large installations.
