Flood Sensor - Spot
AVTECH
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 farther 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.
