INSTALLATION INSTRUCTIONS
1. Mount the receiver box in the desired location using supplied two-sided tape.
2. The receiver connector comes prewired with basic connections to the power supply and the
sensor. Using an appropriate screwdriver, make any additional desired electrical connections
for output contacts or additional sensors per Figure 1. (Note: additional sensors can be
connected to either 6 & 7 or 8 & 9, as wiring space allows.) Then snap the terminal wiring block
into the receiver housing at the mating slot provided.
3. Turn off the main power. Wire the appropriate inputs to the main power source. Wire the blue
and yellow wires (24V AC output) to the plenum wire that is prewired to the power input of the
contact plug. Turn on the main power. The green "Power" indicator light on the receiver will
turn on.
4. Place the sensor(s) where leaking water is most likely to first accumulate (such as the base of
a washing machine, hot water heater, under sink, etc.), or in an HVAC/AC condensate pan to
monitor for potential overflow.
The sensor is magnetic and can be installed horizontally or vertically in conjunction with the
metal plate – see Figure 2. Install the sensor flush to the floor for immediate alarm or at the
desired overflow alarm level.
• Clean the desired location area to ensure the surface is clean for optimum plate adhesion.
• Peel the backing off the metal plate to reveal the adhesive and stick in place.
• Place the sensor on the plate at the desired height, allowing the magnets to secure it
in place.
Note: The sensor features a through-hole that can be used to screw it onto a surface if a more
permanent installation is desired or necessary.
5. Function Test the system as follows:
• Place the sensor on a wet paper towel. The audible alarm will sound.
• Remove the sensor from the paper towel, dry the contact points, and place it back in the
desired location on the metal plate.
• If necessary, press and release the "Reset" button on the receiver to reset the system's
NO/NC dry contact outputs.
TRANSFORMER WIRING INSTRUCTIONS
The supplied transformer has multiple input taps to accommodate different line voltages. If the
existing line voltage you have at your facility is:
120V AC – The WHITE wire from the transformer should be connected to the hot leg of the
input voltage and the black wire to the neutral leg.
208V AC – The RED wire from the transformer should be connected to the hot leg of the input
voltage and the black wire to the neutral leg.
240V AC – The ORG wire from the transformer should be connected to the hot leg of the input
voltage and the black wire to the neutral leg.
The GREEN wire in all cases must be connected to EARTH GROUND.
Each wiring combination as stated above yields the same 24V AC output across the BLUE and
YELLOW wires of the secondary winding of the transformer.
See back cover for Transformer Mounting Instructions.
