FDOOT221, FDO221, FDT221 Automatic fire detectors

Product catalog summary

Overview: The document provides technical specifications and applications for the Sinteso™ C-LINE automatic fire detectors, which are addressable via FDnet. These detectors are designed for early and reliable fire detection with high immunity to deceptive phenomena.

Key Features:

Optimum smoke detection for various applications using signal processing with detection algorithms.
High immunity to environmental and interference factors such as dust, humidity, and electromagnetic interference.
Dual optical sensors and additional heat sensors for enhanced detection and failsafe operation.
Ecological material concept with recyclable materials and environmentally friendly testing.

Detector Types and Functions:

FDOOT221 Multi-sensor Smoke Detector: Utilizes scattered light principle with dual sensors for detecting both dark and light smoke particles. Suitable for environments with deceptive phenomena.
FDO221 Smoke Detector: Uses a single sensor for optical forward scattering to detect smoke particles. Ideal for early detection of smoke-generating fires.
FDT221 Heat Detector: Equipped with redundant heat sensors to detect rapid temperature increases, suitable for environments where optical detection is challenging.
FDX291 Dummy Detector: Used to cover bases without detectors for extended periods.

Installation and Maintenance:

Easy and time-saving mounting with options for surface and recess supply wiring.
Screw-less terminals for tool-free connection and easy detector replacement without new parameter settings.
"One man" testing and maintenance capability, allowing detector replacement without a ladder up to 8 meters in height.

Technical Specifications:

Operating voltage: DC 12…33 V
Operating temperature range: -10…+60 °C (varies by model)
Humidity tolerance: ≤95% relative humidity
Communication protocol: FDnet
Protection category: IP43 to IP54 depending on the base and sealing elements used

Standards and Approvals:

Complies with standards such as CEA 4021, EN 54-7, EN 54-17, and EN 54-5.
Approved by VdS and LPCB with specific approval numbers for each model.

Ordering Information: The document lists part numbers and weights for each detector type, along with references to additional data sheets for accessories and compatibility details.
