Commercial Water Leak Detection Products

Water leaks can cause great damage to your property especially when it comes to electronics. Our water detection products protect your commercial or industrial property by detecting the presence of water before it contacts electronics or other valuables in the building.

When the water leak detection equipment senses a leakage, it will send an alert that a leak has been detected so that the problem can be addressed as quickly as possible. Learn about our water leak detection equipment below.

  • 6 different models of water leak detection products along with a complete line of Water Alert monitors, power supplies, auto-dialers,s and other optional accessories
  • Thoughtful design and construction for convenience and a long service life
  • Water detector alarms are used in a wide range of applications, from computer rooms to mechanical rooms…anywhere undetected leakage can occur.
  • Each Water Alert water sensor alarm is tested 3 times during manufacture and comes with a 5 Year Limited Warranty.
  • Simple installation using instructions furnished with all our water monitoring systems, normally done by maintenance personnel. Typical spacing is one Water Alert water detection sensor for every 300-400 sq. ft.
  • Water Alert water detectors will NOT activate due to high humidity and are not affected if submerged in water for short periods.

Benefits of Using Water Detection Products

  • Reduces lost revenue
  • Lowers water system operational cost
  • Prevents contamination
  • Minimizes lost time managing insurance claims
  • Extends life of facility
  • Prevents property damage
  • Prevents water system liability and increased insurance premiums
  • Prevents or reduces outage events

Water Leak Detection Device Construction

Features and advantages of our exclusive Water Alert® design:

  • Compact design with 5.75” diameter and just 1/25” high, approx 1lb shipping weight
  • ⅛” thick high-impact polystyrene dome-shaped housing for strength and ruggedness
  • 9V DC operating voltage for a safe and simple installation (no conduit required)
  • Epoxy-encapsulated sensing/control circuit avoids problems caused by dirt, fungus, or humidity affecting circuit operation or increase of battery drain with time. The circuitry is impervious to water immersion.
  • SS-2100 has 85 decibel alarm, all other models have 100 decibels (at three feet)
  • Piezoelectric buzzer protected against short-term immersion. Buzzer replaceable if damaged by long-term immersion.
  • Nickel-gold plated adjustable sensing probes are corrosion-resistant. A nylon pellet ensures a positive connection from the probes to the sensing circuit. (Adjustable from 1/64” to ⅛”)

  • The adjustable gold-plated sensing probes are located on the underside of the water detector

Standard Series Water Leak Detection Products & Options

  • Model SSStandard Water Alert detector provides an audible alarm when activated. Used in applications where only a local audible alarm is desired.
  • Model SS-1Water Alert detector provides local and remote alarms when activated. Used in applications requiring a single detector and remote alarm. Often used in noisy or unattended areas.
  • Model SS-2: The Water Alert detector provides an audible alarm when activated. Used in applications where only a local audible alarm is desired and an extended alarm duration is required. (Battery operation- 10 days)
  • Model SS-4Water Alert detector – No audible alarm…Provides isolated dry relay contacts (DPDT) which transfer and hold when activated. Self-resets. Used in applications where tie-in to an existing alarm panel is desired (Building Management System, etc.) and no audible alarm is necessary. Also ideal for extremely harsh environments and can control valves, pumps, and other electrical equipment.
  • Model SS-5: The Water Alert detector provides an audible alarm and isolated dry relay contacts (DPDT) which transfer and hold when activated. Self-resets. Used in applications where tie-in to an existing alarm panel is desired (Building Management System, etc.). Can also be used to control valves, pumps, and other electrical equipment.
  • Model SS-2100Water Alert detector used to tie into all Dorlen’ Series 2100 Monitors. Used in applications where a Dorlen Series 2100 Monitor / Power Supply is desired.
