About Fire Detectors

State-of-the-art Forward / Backward Light Scattering Technology

The advanced optical analysis of light and dark smoke particles mean Cerberus™ PRO detectors are extremely sensitive, virtually immune to false alarms, and provide very early detection. Advanced detectors comply with NFPA 76 (Telecommunication Standard) and are classified as Very Early Warning Fire Detectors (VEWFD). They also provide enhanced detection capability equivalent to ionization detectors. They are also RoHS compliant and meet the standards regarding the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, which makes them environmentally friendly and a great replacement for ionization detectors.

Redundant Sensors

Two thermal and two optical sensors increase the reliability of Cerberus PRO detectors. This redundancy heightens their immunity to deceptive phenomena and increases their detection capability and reliability. Should one sensor fail, the detector will still provide fail-safe operation.


Siemens unique ASAtechnology™ (Advanced Signal Analysis) is a highly advanced technology based on the forward and backward light scattering technology and redundant sensors. The advanced detectors intelligently detect smoke, heat, and carbon monoxide in any environment – without false alarms.
