Avtech RMA-FS2-SEN Installation Notes

AVTECH's Flood Sensor (Spot) monitors
the presence/absence of liquid on a flat
surface. When liquid collects underneath
the blue housing, it bridges the 2 adjustable-
height contacts and trips the sensor. The
contacts, which are 1" apart, arrive 1/32"
off the ground, and adjust individually from
0" to 1/8" high. Self-adhesive feet on the
bottom of the housing allow you to fasten
the sensor to trouble-spots and also provide
a gap to admit water to the contacts.

Install Your Flood Sensor (Spot)

Do not use this sensor in hazardous (classified) locations or life safety applications.

Step 1: Adjust the height of the contacts if necessary.

You may leave the contacts at the factory-adjusted height of 1/32" away from the
floor, or adjust them between 0" and 1/8" high. To simulate the distance to the
floor, rest a straight-edge on the feet closest to the contacts while you adjust them.
• Tighten the contacts clockwise to raise them further away from the floor.
• Loosen the contacts counter-clockwise to lower them closer to the floor.
While you may lower the contacts flush to the floor (0" high), doing so increases
the chance of a false alarm—mere dampness or a film of dirt could bridge the
contacts. Metal, too, forms a complete circuit, so if you place the unit on a metal
surface, be sure to maintain a gap under the contacts.
