Siemens OOHC941 Multi-Criteria Fire and CO Detector with ASAtechnology

The Siemens OOHC941 is an advanced multi-criteria detector that combines optical, thermal, and carbon monoxide (CO) sensing technologies. Utilizing Siemens’ ASAtechnology (Advanced Signal Analysis), it provides reliable detection of various fire types and CO presence while minimizing false alarms. 

Key Features:

• Multi-Sensor Detection: Integrates optical, thermal, and electrochemical CO sensors to detect a wide range of fire signatures and CO levels. 

• ASAtechnology: Employs advanced algorithms to differentiate between actual hazards and deceptive phenomena, reducing nuisance alarms. 

• Forward-and-Backward Light-Scattering Technology: Utilizes unique optical sensing to detect both small and large combustion particles effectively. 

• Field-Selectable Application Profiles: Offers configurable profiles to tailor detection parameters for specific environments, enhancing adaptability. 

• Tri-Color LED Indicator: Provides clear visual status with green (normal operation), yellow (trouble), and red (alarm) indicators for straightforward monitoring. 

Specifications:

• Operating Voltage Range: 12 to 32 VDC

• Standby Current: 0.45 mA

• Alarm Current: 0.45 mA

• Detector Sensitivity Range: 0.5% to 4.0% per foot obscuration

• Air Velocity: 0 to 4,000 feet per minute

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

• Relative Humidity: 0% to 95% non-condensing
