Next, connect the 25´ Sensor Cable to the top or right set of switch sensor connectors on the side of the Flood
Sensor (i.e. see graphic below). This may already be completed as the Flood Sensor is shipped with this already
connected. Note that there are two sets of switch sensor connectors on the right side of the Flood Sensor. If you were
to mount the Flood Sensor to the wall in an upright position, the set of connectors that monitor flood are on the top.
The set of connectors that are on the bottom or left allow users to connect a second
Sensor Cable that monitors for a Flood Sensor Cable “fault”. This would indicate that
the Flood Sensor Cable has perhaps been disconnected from the Flood Sensor, that the
Flood Sensor Cable has a severe pinch or twist that inhibits proper use, or that power
is no longer being supplied to the Flood Sensor device. It is not required to use this
additional sensor feature although it is very beneficial and helps to increase reliability
by insuring that the Flood Sensor is in fact installed and working properly.
The green LED next to the power jack on the Flood Sensor box indicates the current status of the Flood
Sensor. When the LED is solid green, it indicates the sensor is in a normal condition with the Flood Sensor
Cable connected and no water detected. If water is detected, the LED will blink in a quick, constant pattern.
If the Flood Sensor Cable is disconnected, the LED will blink twice, pause, then blink twice again and repeat
the pattern until the cable is reconnected. The status LED is useful for determining if the Flood Sensor is
functioning properly before or after connecting the sensor to Room Alert.
Since the sensor cable that is included with the Flood Sensor cable is 25´ in length and most users do not
locate the device that far from the host Room Alert unit, you may desire to split the sensor cable into two
lengths of approximately 12.5´ each. This would allow you to use both sensor channels on the Flood Sensor.
Naturally, these would connect to two different sensor channels on the Room Alert unit so that you can get
the appropriate alert notification for the specific alert condition being recognized.
Sensor cables can be any low voltage cable such as bell wire, speaker cable, data cable or telephone cable.
Minimum voltage isolation 50v, minimum current carrying capacity 1A. Maximum recommended length is
approximately 100´ although shorter lengths will yield more reliable performance. The sensor cable length
can be extended up to approximately 900´ in length although signal strength can be impacted by other power
devices like generators, UPS or florescent lights. Test your setup to ensure proper operation.
The Flood Sensor Cable itself can be extended in length to create a longer cable that may better meet the
specific application. AVTECH Software manufactures Flood Sensor Cables in 8´ and 24´ lengths. These can
easily be connected end-to-end for extended lengths that are multiples of 8´.
WARNING: DO NOT CUT the Flood Sensor Cable for any reason as this will damage the Flood Sensor Cable. AVTECH
Software has no responsibility for Flood Sensor Cables that have been damaged in handling or modified for any reason.
For instructions on how to connect any sensor to a Room Alert environment monitoring unit, please see the associated
User’s Guide & Reference Manual for that specific model. Please consult this manuals or look online at AVTECH.com

The Screw Connectors On The Sensor ID Boxes Are Volt-Free Contacts Only. Do Not Connect These Terminals To Any Live Circuit.
A Qualified Electrician Should Be Consulted To Test Any Wires You Connect To The Room Alert ID Box For The Presence Of Electrical
Voltages And If Any Are Detected, They Must Not Be Wired To The ID Box. The ID Box May Become Dangerous If You Connect It
To A Live Circuit. Never Connect Main Power To Any Of The Room Alert Sensors Unless Specifically Instructed To Do So Using The
AVTECH Software 5V Power Adapter. If Required, An AVTECH Software 5V Power Adapter Will Be Included With That Sensor.
DO NOT Use Switch Sensors In ‘Explosive’ Environments Unless Approved For Those Environments.
