Why Cerberus Nova fire detectors?

Siemens Cerberus Nova detectors are at the forefront of next-generation fire detection, seamlessly integrating into the Siemens fire safety ecosystem. These cloud-connected, IoT-enabled detectors transform fire safety from a reactive necessity into a proactive, intelligent, and connected solution.

Cerberus Nova detectors are engineered for the digital age, offering unparalleled protection that thinks ahead. They are designed to meet the complex demands of modern environments like healthcare facilities, data centers, and commercial buildings, where uptime, safety, and operational efficiency are paramount. These detectors are not just about detecting fire; they are about intelligent adaptation, predictive insights, and ensuring your building's safety infrastructure is future-ready and sustainable.

With Cerberus Nova detectors, you gain the confidence to keep moving forward, ensuring continuous safety, smooth operations, and uninterrupted productivity, so you can focus on what drives your business.

Key differentiators

  • Cloud-connected & IoT-enabled: Experience real-time monitoring and remote diagnostics, transforming traditional fire safety into a smart, connected solution fully integrated with Building X.
  • Disturbance-Free Testing (DFT (24/7 self-checks): Eliminate disruptive manual testing, ensuring continuous protection without interrupting your operations or occupants.
  • Smoke Entry Supervision (SES) (24/7 self-monitoring): Proactively monitors smoke entry, providing early alerts and enhancing the reliability of detection. Enables remote diagnostics and support
  • ASAplus technology™: Utilizes multi angle, multi-wavelength optical and dual thermal detection to intelligently differentiate between real fires and deceptive phenomena, reducing false alarms and ensure unnecessary evacuations.
  • Data-driven insights: Leverage real-time data for informed decision-making, predictive maintenance, and optimized system performance.
  • Seamless modernization: Designed for compatibility with existing Cerberus fire control panels and existing bases, allowing for easy upgrades and expansions with minimal disruption.
