Siemens FDOT421 Intelligent Addressable Multi-Criteria Fire Detector
The Siemens FDOT421 is an intelligent, addressable multi-criteria fire detector that integrates optical and thermal sensors to provide reliable detection of various fire types. Designed for compatibility with Siemens’ Desigo Fire Safety systems, the FDOT421 offers advanced features to enhance fire detection capabilities.
Key Features:
• Multi-Criteria Detection: Combines optical (smoke) and thermal (heat) sensing technologies to detect a wide range of fire signatures, improving responsiveness to both flaming and smoldering fires.
• Intelligent Addressing: Allows precise identification and monitoring within the fire alarm system, facilitating accurate location tracking and maintenance.
• Advanced Signal Processing: Utilizes sophisticated algorithms to analyze sensor data, enhancing detection accuracy and reducing the likelihood of false alarms.
• Polarity-Insensitive Wiring: Supports polarity-insensitive wiring configurations, simplifying installation and reducing potential wiring errors.
• Built-in Isolator Option: Offers a version with an integrated isolator to enhance system reliability by isolating short circuits on the signaling line circuit (SLC).
