Siemens FDOOTC441 Multi-Criteria Fire/CO Detector with ASAtechnology

The Siemens FDOOTC441 is an advanced, multi-criteria detector that combines optical, thermal, and carbon monoxide (CO) sensing technologies to provide comprehensive fire and CO detection. Incorporating Siemens’ ASAtechnology, it offers high-precision detection while minimizing false alarms by distinguishing between actual fire conditions and deceptive phenomena. 

Key Features:

• Multi-Sensor Detection: Integrates optical, thermal, and CO sensors to detect a wide range of fire types, including both flaming and smoldering fires.

• ASAtechnology: Utilizes forward and backward light-scattering technology to differentiate between real fires and non-threatening events, reducing false alarms.

• Built-in ISOtechnology: Enhances system reliability and circuit integrity by providing advanced addressable fault finding and True Class-X SLC operation.

• Field-Selectable Profiles: Offers 26 application profiles, allowing customization for various environments such as hotels, offices, parking garages, and data centers.

• Supervisory Features: Includes monitoring for temperature and CO concentration thresholds, with a low-temperature warning for sprinkler systems per NFPA 25.

Specifications:

• Operating Voltage: 16-30 VDC

• Current Consumption: Standby: 300 µA; Alarm: 500 µA

• Temperature Range: 32°F to 120°F (0°C to 49°C)

• Humidity Range: 0% to 95% relative humidity, non-condensing

• Approvals: UL 268 7th edition, UL 2075, UL 521, UL 268A, NFPA 72, NFPA 76, FM, CSFM

The FDOOTC441 detector is compatible with Siemens Desigo® Fire Safety and FireFinder XLS/V fire alarm control panels. It is designed for easy installation using the DB-11 series mounting bases and supports both surface and semi-flush mounting configurations.
