Leak Detection

About

Overview

Ever since the invention of indoor plumbing, building owners have worried about water damage. Not much has changed in 200 years except that the cost of a water leak can be thousands of times more expensive than the damp cellar of previous generations…

Leaks in offices, hotels, museums, computer rooms, data centers or other commercial buildings can damage property, data, or customer goodwill.

Critical infrastructure and equipment typically requires both 24/7 availability and absolutely no damage.

Water Leak Detection System

Pentair Thermal Management provides the TraceTek water leak detection system—a versatile modular system with many interchangeable components that can be configured as needed for each application. The broad range of TraceTek alarm modules and modular components allows you to tailor the monitoring approach and layout to the application.

The TraceTek water leak detection system has these basic parts:

  • Sensing cables and probes – these cables and probes directly detect and accurately pinpoint the source of the leak, such as cables used for below raised floors, drip trays overhead piping, flat probes for sumps or damp areas, and miniature probes for tight areas.
  • Leader and/or jumper cables – these are cables that connect the module to the sensing cable/components
  • End termination – this is the end termination on every leg of the sensing cable in the circuit
  • Accessories — the items, such as hold-down clips, that are used to secure the sensing cable in place
  • Sensor Interface Modules – these modules provide the excitation voltage necessary to operate the cable or probes. The SIM then monitors analog current and voltage levels to determine when and where a leak has occurred. The measurements are digitized and transmitted back to the control and alarm panel for user display or interface to higher level systems. These modules can be either a nonlocating alarm module for small area coverage, or an alarm and locating module that can monitor one or more large areas.
Benefits

Some of the oldest TraceTek water leak detection cables have been in continuous service for more than 25 years. TraceTek water leak detection systems provide:

  • Long term reliable systems made with high performance polymers for maximum durability.
  • Cables and probes that directly detect and accurately pinpoint the source of the leak.
  • Digital communications powered independently of the sensor cable so that damage to the sensor cable does not cripple the entire system.
  • A robust digital backbone that gives the ability to independently track many leaks at once, with local, networked or remote alarms and diagnostics.
  • Flexible design options that permit sensor cables to be short or long and deployed on one floor or many levels of the building while being centrally monitored from the most effective locations.
  • Graphic mapping that shows the location of any detected leak on a background graphic of your choosing that flashes an icon in the exact location of the detected leak.
  • Optional fuel sensors to monitor the back-up emergency generators and associated diesel fuel tanks, pipes and fittings (FM7745 compliant).
  • Multiple digital communications protocols and integration to building management systems, email / SMS or web page.
  • Configuration options that automatically shut off pumps or valves where appropriate.
  • Modular assemblies that can be configured for current needs and allow for future expansion of your leak detection system.
  • Ability to monitor up to 250 cables independently of each other.
Technology
Conductive-polymer technology

Conductive polymers are used to extend the life of TraceTek cables. Some of the oldest TraceTek water detection cables have been in continuous service for more than 25 years.

Sensor Cables and Probes for Water Leak Detection
  • TT1000 cable core is built with tough engineering plastics that can resist the load and stress of being on the bottom of a stack of under floor cables.
  • TT1100-OHP is designed for overhead pipes, drip trays and dirty areas. The unique polyester rope over braid provides a wicking action that ensures the first drops of water to hit the sensor cable are absorbed and wicked along the cable until an alarm signal is generated. The rope layer also provides additional mechanical protection in applications where sharp metal edges could be a problem and protects the sensor electrodes in dirty or dusty areas.
  • TT5000 fuel sensor cable and TT-FFS fast acting fuel detection probes can be integrated into the same monitoring system as a simple add-on so that diesel fuel tanks, pipes and fittings associated with emergency generators can be monitored by the same equipment. TraceTek fuel detection components are FM7745 compliant.

Monitors and Alarm Panels

Monitors and Alarm Panels Sensor Interface Modules provide the excitation voltage necessary to operate the cable or probes. The SIM then monitors analog current and voltage levels to determine when and where a leak has occurred. The measurements are digitized and transmitted back to the control and alarm panel for user display or interface to higher level systems.

Digital or Analog?

Don’t be confused by claims to the contrary: All sensing is done at the analog level by measuring voltage, current and resistance. All modern systems convert the analog values to digital values, then use digital telemetry to bring the measurement values to the alarm panel. TraceTek’s combination of analog measurement and digital technology, permits designers to tailor their water leak detection system to larger floor areas, multiple levels and smaller discontinuous areas with ease. As all SIMs speak Modbus, and Johnson Controls’ N2 Open protocol and allow for easy conversion to BACnet, TraceTek leak detection can be a plug-and-play addition to many building management systems.

Multiple methods for remote alarm notification

A wide range of industry standard protocols are used, giving you multiple interface possibilities. Systems are simple to operate, rugged in design and reliable in use. Universal power supply and hazardous location approvals means they can be installed in all environments.
