- Low-Flow Performance: Capable of detecting smoke in airflows as low as 100 ft/min, suitable for a wide range of HVAC applications.
- Control Capabilities: Includes a DPDT relay for direct control of HVAC equipment, such as fan shutdown or damper operation.
- Design: Utilizes a patented telescoping sampling tube and includes a transparent housing cover for easy, fast, and secure installation/visual inspection.
- Power & Integration: Supports multiple power inputs (24 VAC/DC, 120/240 VAC) and is compatible with remote testing accessories, such as the RTS451 or RTS451KEY.
- Tamper Protection: Built-in tamper detection alerts the system if the cover is left open for over 20 minutes.
While now discontinued by the manufacturer, the FSD-751RPL remains a highly dependable component for existing addressable fire alarm systems that require precise, low-flow duct protection.
