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.
