Flood Sensor - Cable
AVTECH
AVTECH’s Flood Sensor - Cable detects liquid when
it bridges any pair of conductive threads twisted
along the length of the patented orange cable.
The cable’s design allows you to position it in a
variety of ways to detect water where it runs or
settles, such as on the oor around valuable IT
equipment; around a pipe that water runs down;
or on a tray in a drop-ceiling beneath a dripping air
conditioner.
Flood Sensor - Cable Package Contents
• One (1) Flood Sensor box
• One (1) Flood Cable w/ 25' RJ-11 leader
• One (1) 25' speaker wire
• One (1) AVTECH 5V power adapter
• Two (2) mounting screws

Switch Ports
Flood Detection Port
Use this port to monitor the presence/absence of liquid. Its switch state becomes Open
(alarm state) when liquid is detected.
Cable Fault Detection Port (Optional use)
If you wish to monitor the state of the Flood Sensor Cable itself, use this port. Its switch
state becomes Open (alarm state) under these circumstances:
• The RJ-11 leader is disconnected from the Flood Sensor box.
• There’s a severe pinch, twist or other physical damage to the orange-twisted Flood Cable.
• Power is no longer being supplied to the Flood Sensor box.

Install Your Flood Sensor - Cable
Do not use this sensor in hazardous (classied) locations or life safety applications.
Step 1: Mount your Flood Sensor - Cable.
Do not allow the Flood Sensor box to come in contact with liquid. The box itself plugs
into main power and must stay dry.
1. Locate the Flood Sensor box away from water and above any anticipated water line—
the box itself plugs into main power and must stay dry. You may mount it using the
two included mounting screws.
2. Run the orange-twisted Flood Cable where water is most likely to run or settle.
Step 2: Connect the Flood Sensor Cable to the Flood Sensor box.
Connect the RJ-11 leader to the RJ-11 port on the Flood Sensor box.
Try to avoid running the leader cable near large electromagnetic
devices or uorescent lights, which produce EMI and can interfere with
sensor readings.
Step 3: Connect the Flood Sensor box to the Room Alert Monitor.
Do not connect the switch sensor inputs (dry contacts) on AVTECH products to any live
circuit.
Use only low-voltage 2-wire cable to connect switch sensor inputs.

Flood Sensor - Cable (RMA-F008-SEN & RMA-F024-SEN)
Your Flood Sensor box comes with one end of the 25' speaker
cable already attached to its Flood Detection switch port, which is
non-polarized. Follow these steps to attach the other end to a
switch port on your Room Alert Monitor:
1. Separate and strip the leads on the free end of the speaker
cable, exposing about ¼" of wire.
2. Run the speaker cable back to your Room Alert Monitor. Try to avoid running it near
large electromagnetic devices or uorescent lights, which produce EMI and can
interfere with sensor readings.
3. Connect the free ends (the ¼" leads) of the speaker cable to an
open switch port on your Room Alert Monitor. Be sure the bare
wire, not the insulation, connects to the port. The leads are non-
polarized, so you may connect either lead to either side of the open
port.
Step 4: Connect your Flood Sensor - Cable to a power source.
Use only the AVTECH 5V power adapter. Others may damage the sensor.
1. Connect the included power adapter to the power port
on the Flood Sensor box.
2. Then insert the power adapter plug in to a power
source.
Notice that the Status LED lights up when the box is
plugged in to power.
Clean Your Flood Cable
Over time, the orange-twisted Flood Cable will accumulate dust, dirt, etc., particularly if it’s
placed on the oor. When the cable gets dirty, it can cause the Flood Sensor to trigger false
alerts.
If you receive false alerts, check the cable to see if it needs to be cleaned. We recommend
disconnecting it and cleaning it using dish soap and a wet rag. Then let the cable sit for 24 to
48 hours to dry, preferably in a location with low humidity so that the cable does not retain
any moisture.

Previous Generation Flood Sensor Cable
In the previous generation of Flood Sensor Cable, the orange-twisted Flood Cable and
the RJ-11 leader are separate components that must be tted together. To assemble the
previous generation Flood Sensor Cable:
• Connect the 4-pin custom jack
on the orange twisted Flood
Cable to the matching port on
the RJ-11 leader.
• Screw the cover down on the plastic threads for a secure t.
When the orange-twisted Flood Cable is disconnected from the RJ-11 leader cable, the
Cable Fault Detection port’s switch state will read as Open.

Use Room Alert Monitor’s Built-In Web Interface
Navigate to Settings Sensors in your Room Alert Monitor’s web interface. The
options you see below will vary depending on your Room Alert model.
1. Scroll down to Switch Sensor Settings.
2. Find the switch sensor label that matches the port you connected your switch sensor
to. For example, if you used the rst switch sensor port on your Room Alert Monitor,
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, “Switch Sen X,” or enter something more
descriptive of up to 15 characters. You may use the following characters in sensor
labels: letters, numbers, spaces, hyphens (-), underscores (_) and periods (.).
4. In Alarm On, select the alarm state (Open or Closed) for your switch sensor. You
may nd the alarm state of your switch sensor under the Features & Specications
section of this Installation Note.
5. In Alarm Prole, which controls light towers and relays on your Room Alert Monitor,
you may leave the default, Prole 1, or choose another prole from the drop-down
menu.
6. Select Save Settings at the top or bottom of the page. Your Room Alert Monitor will
automatically reboot and commit your changes.
