Addressable aspirating smoke detector. Laser detection optics, Part-Flow sampling technique. Programmable sensitivity from 0.1%...1% obs/m. Class B (increased sensitivity). Coverage of an area up to 1600m². Aspirating network with Ø25mm ABS piping with maximum length of 400m. Air temperature -20°C...+60°C. Aspirating network designed using TecnoASD software. Depending on the application, the software sizes and verifies the flow data of the network, defines the detector programming and draws up the project compliance declaration. The detector is equipped with automatic fault controls for: power supply, air flow and internal filter contamination. Serial bus for connecting optional TFT-4.3C repeater panels, which can be used to monitor detector operation. Programmable functions: Prealarm and Alarm signalling thresholds, alarm signalling delay and motor speed. Signalling interface consisting of 6 LEDs. Advanced management with adaptive detection logic, day/night mode, determined by formulas that dynamically relate the functional states of the system devices. RSC® management: programming, remote management and control. Loop connection. Double line isolator. Power supply from external 24V DC source. IP3x protection rating. Operating temperature -5°C...+55C°. ABS enclosure. Metallic grey colour. Dimensions (L x H x D) 260 x 252 x 110mm. EN 54-20:2006 - EN 54-17:2005. Approval certificate: 1415-CPR-128-(C-3/2024).
