Notifier · Fire & Life Safety
Description The FSD‑751RPL is an intelligent photoelectric low‑flow duct smoke detector from Notifier, designed for precise detection of smoke in HVAC duct systems. Technical Specifications Condition New/Never Used Surplus Brand Notifier Category Fire Safety Part Number FSD-751RPL Subcategory Smoke Detector Device Type Duct Smoke Detector Detection Method Photoelectric Relay Type DPDT (Double Pole Double Throw) Relay Input Voltage 120/240 VAC Technology Intelligent / Addressable (FlashScan®) Air Velocity Range 100 to 4,000 ft/min Application HVAC duct smoke detection and fan shutdown Sampling Method Telescoping Sampling Tube (included) Mounting Directly on HVAC duct Weight 2.59 lbs Information About FSD-751RPL The FSD‑751RPL is part of Notifier’s intelligent line of photoelectric duct smoke detectors, engineered to provide accurate and early smoke detection in HVAC systems. Designed for use with Notifier’s FlashScan® addressable fire alarm panels, this model combines precise sensing technology with a low-flow sampling system to monitor air velocities as low as 100 ft/min. Equipped with a DPDT relay, it can directly control HVAC equipment such as fans and dampers in response to smoke events. Built-in tamper detection and compatibility with remote test accessories make the FSD‑751RPL a highly dependable solution for duct-based fire protection. Key Features: Photoelectric Sensing Technology: Delivers reliable smoke detection in HVAC ducts using a high-sensitivity optical sensor. FlashScan® Addressable Protocol: Supports fast, intelligent communication with Notifier panels for precise event identification. Low-Flow Sampling: Operates across duct air velocities from 100 to 4,000 ft/min with patented telescoping sampling tubes. DPDT Relay Output: Enables direct fan shutdown or HVAC system control upon smoke detection. Tamper Detection: Triggers a trouble signal and fan shutdown if the unit’s cover is left open for more than 20 minutes. Remote Testing & Annunciation: Compatible with RTS451, RTS451KEY, and RA400Z for simplified system inspection and status display. Multi-Power Input: Accepts 24 VDC, 24 VAC, or 120/240 VAC auxiliary power input to meet diverse installation needs. Durable Housing: Built for duct-mount applications with strong materials and easy-access maintenance design. Environmental Ratings: Operates in temperatures from 32°F to 131°F (0°C to 55°C) and humidity up to 93% non-condensing. The Notifier FSD‑751RPL offers a powerful combination of intelligent detection, HVAC integration, and flexible mounting, making it ideal for commercial buildings requiring reliable duct smoke sensing. While now discontinued, it remains a trusted component in existing systems and a reference point for current-generation addressable duct detectors.
