Conventional Optical Smoke Detector, SFP-CSD-001

The SelectFire Plus SFP-CSD-001 Conventional Optical Smoke Detector is designed for use in conventional fire alarm systems and is approved to the European Standard EN54-7:2018 for smoke detectors in fire alarm systems.

The catalogue states that the detector has undergone rigorous independent testing, including fire sensitivity tests, false alarm resistance tests, and durability and design tests to ensure reliability, quality and resistance to nuisance alarms.

The detector operates on the photo-electric light scattering principle. When smoke particles enter the chamber, they scatter the light. A photodetector senses the scattered light and triggers an alarm when the signal exceeds a predetermined threshold.

Key Features:
• Conventional optical smoke detector approved to EN54-7:2018.
• Dual Emitter with 2 wavelengths and multiple light paths to improve smoke detection accuracy.
• Split-spectrum sensing technology to help reduce false alarms caused by dust and environmental contaminants.
• Designed to detect larger smoke particles typically produced in the early smouldering stages of a fire.
• Less sensitive to small fast-burning particles or steam, helping reduce nuisance alarms.
• Drift compensation automatically adjusts sensitivity as the detector becomes dirty or ages.
• Remote LED connection available through dedicated terminals.
• Red LED remains lit in alarm condition.
• Red LED flashes in fault condition.
• Zone connection terminals are polarity insensitive.
• Use with Universal Base model SFP-BSH-012.
