Description
The S1‑SL‑2000‑P is a genuine OEM duct smoke detector designed to detect smoke and combustion products inside HVAC ductwork — protecting buildings by alerting to fire risk and enabling timely system shutdown or alarm activation. It’s engineered for commercial, industrial, and residential HVAC‑ventilation systems, providing early smoke detection before fire spreads through ducts.
Key Features
- Photoelectric Smoke Detection — Uses light‑scattering optical sensing to reliably detect smoke particles carried by air through ductwork.
- Universal Voltage & Multi‑Power Compatibility — Supports multiple power inputs (24 VAC/VDC, 115 VAC, or 230 VAC), making installation flexible for different HVAC and building systems.
- Wide Airflow Range Suitability — Designed to operate reliably across a broad air‑velocity range (from ~100 to 4,000 ft/min), covering many types of duct sizes and flow conditions.
- Compact, Retrofit‑Friendly Form Factor — Relatively small duct‑mount housing (approx. 15″ × 5″ × 4″) — makes installation or retrofit convenient even in existing duct layouts.
- Alarm & Trouble Relay Outputs — Built-in relay contacts to trigger alarms, shutdown fans or HVAC equipment, or interface with building‑automation/fire‑management systems when smoke is detected.
- No‑Tools Maintenance & Sample‑Tube Design Options — Designed for ease of service, with accessible cover and optional sampling‑tube kits for different duct widths (though “‑P” version often listed as “no sample tube”).
- OEM Reliability & Compliance — As a York (or equivalent OEM) component, it meets relevant safety and code requirements for duct‑mounted smoke detection (UL / cUL / CSFM / MEA where applicable).
