Vertiv Geist FS-15 Flood Sensor

Meet the Vertiv Geist FS-15 Flood Sensor, a precision conductivity-based device designed to detect water presence quickly and reliably. Built for critical facilities, data centers, and mechanical rooms, the FS-15 delivers fast, low-latency alerts when moisture or leaks are detected. With a 0-5VDC analog output and a generous 15-foot (4.5 m) cable, this sensor is engineered for flexible deployment, easy integration with Geist monitoring systems, and scalable protection across multiple zones. Its simple, scalable design helps facilities minimize water damage risk, reduce downtime, and protect expensive equipment with proactive flood detection.

• Precision conductivity-based flood sensing: The FS-15 uses conductivity measurements to distinguish water from dry surfaces, providing fast, accurate detection of even small leaks. This approach minimizes false alarms in environments where moisture may accumulate from humidity or harmless spills, while ensuring that any actual intrusion is promptly reported to the Geist monitoring system. The sensor’s 0-5VDC output is easy to read by standard analog inputs, ADCs, or building management interfaces that support voltage-based sensor data, enabling seamless integration into existing infrastructure monitoring workflows.
• Flexible deployment with a 15 ft / 4.5 m cable: The included long cable gives you freedom to place the sensor in strategic locations, from under cabinets and behind racks to near sump basins or along floor edges. The extended reach reduces the need for additional wiring runs and makes it practical to protect multiple high-risk zones without compromising room aesthetics or cable management. The weather- and environment-resilient cable is designed to endure the conditions typically found in data centers, lab spaces, and mechanical rooms.
• Scalable network capability for multiple sensors: One or more FS-15 flood sensors can be connected to each analog input or Analog to Digital Converter (ADC). Wired in parallel, the system detects a leak if any connected sensor experiences moisture. This scalable approach lets you patrol larger areas with fewer inputs, while preserving precise location information through your Geist controller's configuration and alert rules. Whether you’re protecting a rack row, a raised-floor corridor, or a utility closet, the FS-15 offers flexible topology options that adapt to your facility’s evolving layout.
• Seamless Geist ecosystem integration: The FS-15 is designed to work with Vertiv Geist monitoring technology, enabling straightforward setup, alerting, and data logging within Geist-enabled dashboards. Its analog 0-5V output maps directly to Geist controllers and ADC inputs, enabling real-time flood detection, trend analysis, and event-driven notifications. With Geist, you can correlate flood events with other environmental metrics such as temperature, humidity, and airflow, creating a holistic monitoring strategy that helps teams respond quickly and protect critical assets.
• Durable, easy-to-install design for reliability: The FS-15 emphasizes low-maintenance operation and straightforward installation. Its passive sensor design requires no power source at the sensing node, reducing failure points. The 15 ft cable and robust construct are intended for long-term service in demanding environments, while the conductivity-based sensing method provides dependable detection even when moisture levels fluctuate. This sensor is ideal for IT rooms, data centers, laboratories, and other spaces where rapid leak detection translates into reduced risk and faster incident response.

How to install Vertiv Geist FS-15 Flood Sensor

• Plan placement: Identify high-risk areas where water intrusion is most likely to occur, such as under server racks, near cooling units, around water-cooled equipment, or along floor perimeters. Choose locations where the sensor will reliably contact any leaking liquid without being obstructed by furniture, shelving, or cables.
• Prepare wiring: Uncoil the 15 ft cable and route it along approved paths, avoiding pinch points, heat sources, or areas where abrasion could occur. Use cable management accessories as needed to keep the run tidy and accessible for maintenance checks.
• Connect to the Geist system: Attach the sensor’s analog output to an available analog input or ADC on your Vertiv Geist controller or monitoring device. If you are deploying multiple FS-15 sensors, wire them in parallel to the same input per your system’s configuration and the guidance provided by Geist.
• Configure thresholds and alerts: In the Geist management interface, configure the flood detection input for the 0-5 VDC range, specify alert conditions, and set notification channels (local alarms, email, SMS, or SIEM/ECM integrations). Map the sensor to the appropriate zone or location tag to ensure clear incident localization in dashboards and reports.
• Test and document: After installation, simulate a leak by applying a small amount of water to the sensor and verify that the Geist system registers the event and triggers the configured alert. Confirm that the corresponding log entry, dashboard alert, and any connected alarms are functioning. Label the installation point with a site note for future maintenance and audits.

Frequently asked questions

• Q: What problem does the Vertiv Geist FS-15 solve? A: It provides fast, reliable detection of water presence using conductivity sensing. This enables prompt notifications and automated responses to prevent water damage to critical equipment in data centers, labs, and mechanical rooms.
• Q: How does the FS-15 connect to monitoring systems? A: The FS-15 outputs a 0-5 VDC analog signal that can be read by standard analog inputs or ADCs on Vertiv Geist controllers. It supports wiring multiple sensors in parallel to a single input, allowing scalable protection across zones.
