Siemens OH921 Multi-Criteria Fire Detector
The Siemens OH921 is an intelligent, addressable multi-criteria fire detector that integrates optical (smoke) and thermal (heat) sensing technologies. Designed for compatibility with Siemens’ Cerberus PRO and FireFinder XLS fire alarm control panels, the OH921 offers advanced features to enhance fire detection capabilities.
Key Features:
• Multi-Criteria Detection: Combines photoelectric and thermal sensors 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.
• Built-in ISOtechnology: Features integrated isolation technology to enhance system reliability by isolating short circuits on the signaling line circuit (SLC).
• Tri-Color LED Indicator: Provides clear visual status with green (normal operation), yellow (trouble), and red (alarm) indicators for straightforward monitoring.
