WARNING
Read this
Manual BEFORE using this equipment.
Failure to read and follow all safety and use information can result in death,
serious personal injury, property damage, or damage to the equipment.
Keep this Manual for future reference.
WARNING
You are required to consult the local building and plumbing codes prior to
installation. If the information in this manual is not consistent with local
building or plumbing codes, the local codes should be followed.
Inquire with governing authorities for additional local requirements.
NOTICE
Use of the SentryPlus Alert technology does not replace the need to comply
with all required instructions, codes, and regulations related to the
installation, operation, and maintenance of the backflow preventer to which it
is attached, including the need to provide proper drainage in the event of a
discharge.
Watts is not responsible for the failure of alerts due to connectivity or
power issues.
Monitor relief valve discharge with smart and connected sensor technology to
detect flooding and transmit notification. The BMS Flood Sensor Retrofit
Connection Kit upgrades existing installations by integrating and activating
the sensor to enable functions for flood detection. When excessive relief
valve discharge occurs, the sensor energizes a relay signaling flood detection
and triggers real-time notification of potential flood conditions through the
building management system.

NOTICE
When installing an air gap, attach the air gap brackets directly onto the
flood sensor.
Requirements
-
2 Phillips screwdriver
- 120VAC, 60Hz, GFI-protected electrical outlet (for kit power adapter), or power source ranging from 12V to 24V
- Wire stripper
Install the Flood Sensor and Activation Module
Install the flood sensor with the interface pointing in the same direction as
the valve flow arrow.
The activation module receives a signal from the sensor when a discharge is
detected. If the discharge meets the conditions of a qualifying event, the
normally open contact is closed to provide a signal to the BMS input terminal.
Custom Flood Sensor Settings
The default settings on the activation module for detecting discharge are
suitable for the assembly series. However, the DIP switches can customized for
a different wet threshold and time delay. Scan the QR code for more
information.

- Position the flood sensor on the relief valve.
- Use the #2 Phillips screwdriver to attach the sensor to the relief valve.
- Ensure the sensor interface points in the same direction as the valve flow arrow.
- Remove the dust cover from the sensor.
- Press the activation module onto the sensor.
- Check that the module is fully seated to seal the O-ring and to make electrical contact.
NOTICE
Retain the dust cover to protect the flood sensor when the activation module
needs to be removed or replaced.
Attach the Activation Module Cable to the BMS Controller
The 4-conductor activation module cable should be attached to the BMS
controller to transmit a normally open contact signal and provide power to the
activation module. The contact signal closes when a discharge is detected.
To connect the module cable to the controller
-
Use the wire stripper to cut away enough insulation to expose 1 to 2 inches of the conductor wires.
-
Insert the white and green wires into the input terminal.
NOTICE
Either the BMS power source (ranging from 12V to 24V) or the 24V DC power adapter provided can be used. With each power source, an earth ground connection is required.
If using the optional power adapter, skip to the next set of instructions. Be sure to use the ground wire provided if there is no other earth ground on the BMS controller. -
Insert the red wire in the power terminal. (A power source ranging from 12V to 24V is required.)
-
Insert the black wire in the ground terminal.
WARNING
The earth ground must be connected to the BMS controller before the flood
sensor is put in operation.
To use the optional 24V DC power adapter
Distinguish the positive wire from the negative one. The positive wire has
white stripes and must be inserted into the power terminal; the negative wire,
into the ground terminal. 
- Connect the positive power adapter wire (black with white stripe) to the red wire of the activation module cable and insert the wires into the power terminal.
- Connect the negative power adapter wire (black with no stripe) to both the black wire of the activation module cable and the ground wire (if needed) then insert the wires into the ground terminal.
- Plug the power adapter into a 120VAC, 60Hz, GFI-protected electrical outlet.
- The flood sensor LED is steady green when the unit is ready.
