Cerberus PRO Advanced Detectors

Detectors with Exceptional Technology

Siemens unique ASAtechnology™ (Advanced Signal Analysis) provides Cerberus™ PRO advanced detectors (OOH941 & OOHC941) with an exceptionally fast response to flames caused by the combustion of liquid and solid matter. They are also highly reliable in preventing false alarms caused by deceptive on-site phenomena like:

  • Machine exhaust gases

  • Dust

  • Steam

Detectors with  ASAtechnology provide both fire and carbon monoxide (CO) detection with innovative technology for maximum life safety. The additional CO sensor provides the earliest detection of CO-generating fumes independently from fire. The CO detector complies with the requirements of the fire safety and carbon monoxide codes and standards UL 2075 and NFPA 720.

Customizable Protection in Any Environment

Cerberus PRO Advanced detectors can be optimally tailored to meet current environmental requirements. Offering more than 20 application-specific detection profiles, they can be adjusted to the expected environmental condition. You can also easily and quickly change between the profiles, should the conditions change. This makes the advanced detectors a safe and long-term investment.

Cerberus PRO Advanced detectors are especially suited for:

  • Data centers and IT equipment

  • Telecommunications facilities

  • Hospitals and nursing homes

  • Restaurants and small commercial kitchens

  • Auto repair shops and parking garages

  • Industrial production facilities

  • Warehouses

  • Power generation facilities

Advanced Detectors




ASAtechnology fire detector OOH941

• Utilizes ASAtechnology for excellent early detection and rejection of deceptive phenomena

• 20+ selectable detection profiles

• UL-listed as a high sensitivity pre-alarm
