WATTS LF919 Series Cellular Flood Sensor Retrofit Connection Kit

Important Information

| 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.

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.

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 Cellular 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 SynctaSM application.

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 88009424.

A. Activation module with 8′ conductor cable and ground wire

B. Cellular Gateway with mounting tabs and screws

C. 24V Power adapter

D. Small sensor for valve sizes ½” to 1″; large sensor, valve sizes 1¼” to 2″

When installing an air gap, attach the air gap brackets directly onto the flood sensor.

Requirements

• 2 Phillips screwdriver

• Wire stripper
• Suitable location within 8 feet of the flood sensor for mounting the Cellular Gateway on a wall or structure
• 120VAC, 60Hz, GFI-protected electrical outlet
• Ground wire running from the Cellular Gateway to the ground point
• Cellular network connection
• Internet browser

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 Cellular Gateway 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.

1. Position the flood sensor on the relief valve.
   

2. Use the #2 Phillips screwdriver to attach the sensor to the relief valve.
   

3. Ensure the sensor interface points in the same direction as the valve flow arrow.
   

4. Remove the dust cover from the sensor
   

5. Press the activation module onto the sensor.
   

6. Check that the module is fully seated to seal the O-ring and to make electrical contact.
   

Retain the dust cover to protect the flood sensor when the activation module needs to be removed or replaced.

Set Up the Cellular Gateway

When identifying a location to mount the Cellular Gateway, choose an area away from large metal objects and structures that can block cellular signal. The cellular antenna is placed inside the housing on the upper right side. Ensure that the antenna side is clear of walls, wires, pipes, or other obstructions.

These instructions cover the connection of the activation module cable to the terminal block of the Cellular Gateway. The 4-conductor activation module cable should be attached to the Cellular Gateway to transmit a normally open contact signal and provide power to the activation module. The contact signal closes when a discharge is detected.

When attaching the power adapter to the Cellular Gateway, 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.

The earth ground must be connected to the Cellular Gateway before the flood sensor is put in operation.

Attach the activation module cable to the device before or after it is mounted to a nearby wall or structure with the mounting tabs and screws. Collect the Cellular Gateway and mounting materials, power adapter, and Phillips screwdriver, and wire stripper for this segment of the installation.

To connect the module cable to the device

1. Remove the transparent cover from the device.
2. Use the wire stripper to cut away enough insulation to expose 1 to 2 inches of the conductor wires and feed the cable through the bottom port.
3. Insert the white wire and the green wire into the first and second terminals of INPUT 1.
4. Feed the power adapter cord through the bottom port.
5. Connect the positive (BK/WH) power adapter wire to the red wire of the activation module cable and insert the wires into the PWR terminal.
6. Connect the negative (BK) power adapter wire to both the black wire of the activation module cable and the ground wire then insert the wires into the GND terminal.
7. Skip MOD+ and MOD-. Reserved.
8. Reattach the device cover and plug the power adapter into a 120VAC, 60Hz, GFI-protected electrical outlet.

If adding a second flood sensor to the configuration, insert the white and green wires into the first and second terminals of INPUT 2, the red wire into the PWR terminal, and the black wire into the GND terminal.

GATEWAY TERMINAL BLOCK

Verify the Connections

A cellular network signal is required for successful installation.

Upon initialization, the Cellular Gateway begins the start sequence automatically. The process may take up to 10 minutes to reach steady state. Check the status of the LED indicators to confirm connectivity.

To validate the connections, press the TEST button on the Cellular Gateway to send a test message through the Syncta app.
To restore the factory state of the Cellular Gateway and restart the startup sequence, press the RESET button. This causes all ongoing operations to cease.

Call customer service if you need assistance with technical details.

FLOOD/INPUT1| Unlit| No relief water discharge is occurring
Steady orange| Relief water discharge is occurring (This state remains for the duration of the discharge.)
INPUT2| Unlit| No relief water discharge is occurring
Steady orange| Relief water discharge is occurring (This state remains for the duration of the discharge.)

Configure the Syncta App

These instructions cover the minimum user input needed to install and configure the Syncta app for use with the flood sensor. An internet connection is required for laptop or mobile device.
