Flood Sensor (Spot) (RMA-FS2-SEN)
Installation Note
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.
Flood Sensor (Spot) Package Contents
•One (1) Flood Sensor with 25' low-voltage 2-wire cable attached
•One (1) 9V alkaline battery
•One (1) Installation Note (You’re reading it now.)
Install Your Flood Sensor (Spot)
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.
Do not use this sensor in hazardous (classified) locations or life safety applications.

Step 2: Connect the battery.
Your Flood Sensor (Spot) comes with a 9V alkaline
battery inserted into the retainer clip under the housing.
Push the snap connector completely on to the
battery contacts. The snap connector arrives
partially off to prevent the battery from discharging while
it’s stored and shipped.
Use only alkaline batteries in your sensor, and replace the
battery at least once a year. If your Flood Sensor (Spot)
gets activated often, you may need to replace it sooner.
Step 3: Mount your Flood Sensor (Spot).
1. Place your Flood Sensor on a flat surface in the area most prone to collect water.
2. You may simply rest the unit on its feet or remove the backing on the pads to stick it to
the surface. In either case, keep the feet on the unit: they create a gap necessary to allow
water to get to the contacts. If you remove them, the housing and surface may form a
seal, and water won’t reach the contacts until it’s risen up the sides or over the top.
Step 4: Connect your Flood Sensor (Spot) to Room Alert.
Your sensor comes with one end of a 25' low-voltage 2-wire cable already attached. The
leads are non-polarized.
1. Run the cable from the sensor back to your Room Alert monitor
or WiSH Sensor.
2. Connect the exposed leads to an open switch sensor port on your
Room Alert or WiSH Sensor. Again, the leads are non-polarized,
so you may connect either lead to either of the port’s contacts.
Test Your Flood Sensor (Spot)
Once you have inserted the battery and connected to Room Alert, you may easily test the sensor
by bridging the contacts with a paper clip.
Do not connect the dry contacts on AVTECH products or other electrical appliances
to live circuits.
Use only low-voltage 2-wire cable to connect dry contacts.

Configure Your Flood Sensor (Spot)
With Room Alert’s Built-In Web Interface
Navigate to SettingsÆAlarm Options in your Room Alert web interface. The options you
see below will vary depending on the model.
1. Scroll down to “Switch Sensor Settings.”
2. Find the switch sensor label that matches the port you connected your sensor to. For
example, if you used the first switch sensor port on your Room Alert, look for “Sensor 1
Label”; if you used the second, look for “Sensor 2 Label,” and so on.
3. In “Sensor X Label,” you may leave the default name or enter something more
descriptive, such as “Basement Fld 6” or “Fld Spot Rm 2.”
4. In “Alarm On,” choose “Open.” The normal state of the Flood Sensor (Spot) is
“Closed,” which means the sensor does not detect liquid.
5. For models with the “Use Alarm Profile” feature: if you have configured Alarm Profiles
in the Alarm Options screen, you may choose a profile from the drop-down menu. The
default is “Profile 1.”
6. Click Accept Changes at the bottom of your screen to temporarily save your settings.
You may now navigate to another screen; however, if you close the web interface before
the next step, you will lose your changes.
7. Click Save Settings in the navigation bar to the left of your screen. Your Room Alert
will automatically reboot and commit your changes.
