Description
Core Function
Fire detection function: Utilizing the photoelectric detection principle, it can detect visible smoke generated by smoldering or slowly burning materials (such as soft furniture, plastic foam, etc.), as well as "smoke" produced by overheated but unburned PVC. These detectors are particularly suitable for general applications and areas where there is a possibility of cable overheating, such as electrical service areas.
Alarm output: When smoke enters the detection chamber, the smoke particles will scatter the infrared light pulse onto the photodiode, triggering the alarm signal output.
Main Feature
1. Class certification: Obtained approval from all major classification societies for use in ships, and certified in accordance with the EN54 standard approved by LPCB.
2. Wide voltage operating range: Supports low operating voltages ranging from 10.5Vdc to 33Vdc, suitable for different power supply environments.
3. Anti-interference design: By adopting a novel design of asymmetric sampling chamber and signal processing technology, it can effectively prevent unnecessary alerts caused by very small insects.
4. Installation is convenient: Specifically designed for quick installation, the wiring polarity is independent, and there is no need to distinguish between positive and negative poles.
5. Replacement compatibility: This model can replace the FDS511B, FDS512B, FDS512B-J plasma-type smoke sensors, facilitating system upgrades and maintenance.
6. Application scope: Mainly applied in the fire protection system, and also used in the construction of security systems.
