WATTS IS-RFK-FS-957 BMS Sensor Retrofit Connection Kit

WARNING

• Read this Manual BEFORE using this equipment. Failure to read and follow all safety and use infor-mation can result in death, serious personal injury, property damage, or damage to the equipment. Keep this Manual for future reference.
• 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 issues, power outages, or improper installation.
Monitor relief valve discharge with smart and connected sensor technology to detect flooding and trigger notification. The BMS Flood Sensor Retrofit Connection Kit upgrades existing installations by integrating and activating the sensor to enable functions for flood detection. When a qualifying 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.

Kit Components

The retrofit connection kit for installing and activating the flood sensor includes the items shown below. If any item is missing, speak with your account representative about ordering code 88009419.

NOTICE

• The connection kit is suitable for installation on the specified valve series only.
• When installing an air gap, attach the air gap brackets directly to 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
Attach the flood sensor and the activation module to the backflow relief valve. The activation module receives a signal from the flood 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 switches can be customized for a different wet threshold and time delay. Scan the QR code for more information.

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. Follow the procedures below to connect the cable, ground wire, and power adapter (optional) to the controller. (See the wiring diagram for visual reference.)

To connect the cable to the controller

1. Use the wire stripper to cut away enough insulation to expose 1 to 2 inches of the conductor wires.

2. 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.

3. Insert the red wire in the power terminal. (A power source ranging from 12V to 24V is required.)

4. 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.

1. 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.
2. 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.
3. Plug the power adapter into a 120VAC, 60Hz, GFI-protected electrical outlet.

The flood sensor LED is steady green when the unit is ready.
