Stop small leaks from becoming equipment damage. The Vertiv FS-15 is a conductivity-based flood sensor designed to detect the presence of water at the point of intrusion. Its 0-5 VDC output makes it straightforward to integrate into compatible monitoring systems, while the included 15 ft cable gives you the reach needed to position the sensor along rack bases, under raised floors, or near condensate and plumbing risk points. For infrastructure teams, placement matters. The FS-15 is built for targeted detection where early warning has the most value: beneath cooling units, around perimeter walls, and in cabinet rows where a single leak can interrupt service. By identifying water at the source, it helps reduce response time and limits the chance of downstream damage to power, compute, and network assets. This is the kind of sensor chosen when the cost of missed detection is far higher than the cost of monitoring. Simple, direct, and purpose-built, the FS-15 adds a practical layer of protection to facilities that cannot afford avoidable downtime.
