Product catalog summary

Overview: The document provides detailed information on the Sinteso™ C-LINE automatic fire detectors, specifically models FDOOT221, FDO221, and FDT221, designed for the FDnet detector bus. These detectors are ideal for various applications, offering early and reliable fire detection with advanced immunity to false alarms.

Key Features:

Resistant to environmental factors such as dust, moisture, and extreme temperatures.
Signal processing with detection algorithms for accurate detection.
Supports disturbance-free testing with DFTtechnology™.
Integrated line separator and internal alarm indicator with 360° visibility.
Environmentally friendly with reusable materials.

Types of Detectors:

FDOOT221 Multi-sensor Smoke Detector: Utilizes optical forward and backward scattering with additional heat sensors for enhanced detection.
FDO221 Smoke Detector: Employs optical forward scattering with an integrated temperature sensor.
FDT221 Heat Detector: Features two redundant heat sensors for reliable temperature monitoring.

Installation: The detectors are designed for easy and efficient installation with features like screwless connection terminals and compatibility with various mounting bases. They support 'one-man' testing and maintenance.

Technical Specifications:

Operating voltage: DC 12…33 V
Operating temperature range: -10…+60 °C (varies by model)
Protection category: IP43 to IP44 depending on the base used
Standards: EN 54-7, EN 54-17, EN 54-29

Approvals: The detectors have multiple certifications including VdS, LPCB, FM, and DNV GL (marine).

Disposal: Devices must be disposed of according to European Directive regulations and not as domestic waste.
