Unchecked water leaks don’t just damage buildings—they disrupt operations, destroy data centers, destroy and corrode HVAC infrastructure. BAPI’s water leak detection system is designed to catch leaks early and integrate directly into your building’s control infrastructure—with rugged components built for demanding environments.


Fast Detection. Simple Integration. Built to Last.

At the core of the system is the BAPI Water Leak Detector—a compact unit housed in an industrial-grade enclosure that connects to multiple types of water sensors.

Key features include:

  • Rapid detection: Triggers within seconds of water contact across the sensor.
  • Dual 5A SPDT relays: Supports dry-contact outputs for integration with alarms or BAS—no external converter needed.
  • Universal 24V power input: Accepts both AC and DC with built-in reverse polarity protection.
  • Status LEDs: Green for power, red for alarm condition.
  • Reset options: Field-selectable Auto or Manual reset to match your safety protocols.
  • Industrial durability: Enclosure is NEMA 4/IP66 rated, UV-stable, and UL94V-0 flame-rated.

Extended Coverage with Rope Sensor Technology

When coverage area matters more than pinpoint detection, BAPI’s Rope Sensor offers a plenum-rated solution that can monitor long lengths of flooring, wall perimeters, and cold aisle enclosures.

Key features include:

  • Full-length detection: Senses water anywhere along its cable—ideal for wide or irregular zones.
  • Flexible lengths: Available in 10 ft, 25 ft, 50 ft, and 100 ft segments.
  • Plenum-rated construction: Meets UL 910 for use in air-handling spaces.
  • Rugged design: Polypropylene braid with corrosion-resistant internal conductors.
  • Reusable: Can be dried and reused after water exposure.
  • Simple mounting: Attaches with adhesive clips, magnets, or cable ties.
  • Wide operating range: Performs reliably from 32 °F to 167 °F.

This makes it ideal for:

  • Raised-floor data centers
  • Equipment rooms with large drip zones
  • HVAC corridors or server aisles where leaks could travel

Reliable Hardware in Harsh Environments

Both the detector and sensors are made for industrial conditions. The detector’s polycarbonate enclosure is UV-stable, NEMA 4/IP66-rated, and suitable for indoor or outdoor installation. Operating ranges stretch from –4 °F up to 158 °F.

The rope sensor is equally robust—built with corrosion-resistant internal conductors, a durable polypropylene braid, and rated for up to 167 °F. It’s approved for plenum spaces and passes UL 910 flame and smoke requirements.



Quick Setup. Zero Complexity.

Installation is straightforward:

  • Mount the detector using screws or conduit fittings
  • Connect 24V power and your chosen relay output
  • Lay the sensor where water is likely to appear and secure it with clips
  • Power the unit and test with a small amount of water to confirm triggering

Setup typically takes less than 30 minutes per location, and no special tools are needed.

Ordering Configurations

You can pair the detector with multiple sensor types:

  • Integral probe (factory-attached)
  • Remote probe (5–25 ft)
  • Rope sensor (10–100 ft)

Each combination is built to order using a modular part number.
