Infrared smoke sensor CERBERUS NOVA

thermistoropticalindoor

Overview
Cerberus Nova detectors are next-generation, cloud-enabled fire detectors from Siemens, designed for continuous, intelligent fire detection in modern environments (healthcare, data centers, commercial buildings). They provide proactive protection with advanced multi‑criteria sensing, self-testing capabilities, cloud connectivity and sustainable design.

Key capabilities

• ASAplus multi‑criteria detection using multiple optical and thermal sensors to reduce false alarms while ensuring early detection
• Disturbance‑Free Testing (DFTtechnology™) for unlimited automated self-tests without interrupting building operations
• Smoke Entry Supervision (SES) on -S models: Cover Detection and Grid Supervision to ensure smoke reliably reaches the detection chamber
• Cloud‑enabled integration with Building X Fire Apps for remote monitoring, multi‑site visibility, mobile notifications and test/report management
• Backward compatibility with existing detector bases and Cerberus panels; firmware updatable to add features and maintain compliance
• EcoTech certified sustainable design with recycled/secondary materials and reduced material usage

Primary benefits

• Protect operations and reputation by significantly reducing false alarms and unnecessary evacuations
• Maximize uptime and productivity with continuous protection and testing without operational interruptions
• Reduce total cost of ownership through modernization without full system replacement and remote monitoring to lower service costs
• Support sustainability goals with EcoTech certification, recycled plastics in housings and reduced material weight
• Gain full visibility and control with Building X cloud services and predictive maintenance insights

Integration, installation and maintenance

• Works with Sinteso and Cerberus PRO systems; compatible with existing detector bases (no rewiring required)
• Mimic mode support for older panels; latest panel software recommended to enable full feature set
• Firmware updates via on‑site tools (Fire Field Assist FDUL2901 and Electronic Detector Tester FDUD2912)
• Installation and commissioning supported by Building X Fire Install app and standard Siemens commissioning tools

Use cases

• High‑sensitivity environments with high cost of downtime: data centers, hospitals, critical infrastructure
• Buildings with frequent deceptive phenomena (steam, dust, cooking) requiring reduced false alarms
• Facilities targeting sustainable product lifecycles and reduced material footprint

Technical features / specifications
