Leak Detection For The FMS

The SD spot leak detector is designed to primarily function with RLE’s FMS environmental monitoring controller.  The SD comes with a two-wire open lead that allows it to be wired directly to the controller’s terminal block.

Spot detectors are ideal for small spaces, and are the most economical way to detect fluids in confined areas, such as condensation drip pans.

The SD functions like a switch – the circuit remains open until a leak is detected.  The sense probes detect a leak, which causes the circuit to close, which then triggers an alarm.

Key Features

  • No exposed metal sensing posts – nothing to rust or corrode
  • Potted electronics
  • Functions when submerged in water
  • Adjustable probes are easily adjusted to desired height
  • Can be screwed or ram set to floor or baseboard
  • Small footprint/enclosure
  • Simple installation
  • Ideal for tight areas

Power: The SD is usually powered by the RLE FMS.  In the event that it is not used in conjunction with the FMS, it does require an isolated power supply.

  • 24VDC (±10%) Isolated @ 0.1A max.; requires RLE power supply PSWA-DC-24-ST (not included)
    • If a DC power supply is used the SD will be a latching device – once an alarm is detected, the spot detector will remain in an alarm state until power is cycled to the SD.
  • 24VAC (±10%) Isolated @ 0.1A max.; requires RLE power supply WA-AC-24-ST (not included)

Solid State Output: 12-36VAC @ 0.01A min., 0.1A max.; 18-36VDC @ 0.01A min., 0.1A max.
