New Valve Installation
The sensor connection kit includes four (4) deflectors marked by size. Select the size designed to fit the backflow relief valve of the installation.

1. Remove the flood sensor from the valve.
2. Align the grooves of the deflector with the internal ribs of the sensor and insert the deflector inside the flood sensor.
3. Position the flood sensor on the relief valve and align the deflector to fit inside the relief valve.
4. Use a #2 Phillips screwdriver to tighten the captive screw.

Existing Valve Installation
The following procedures include the deflector with the installation of the sensor connection kit.

1. Align the deflector to fit inside the relief valve. (For Series 009, sizes 1 to 2 only. Some sensor connection kits include multiple deflectors. Install the deflector designed specifically  for the backflow valve size in use.)
2. Position the flood sensor on the relief valve and insert the two mounting bolts.

Mount the Activation Module
Set the SW1 DIP switch on the activation module according to the wet threshold table below, then attach the module to the flood sensor. 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: DIP switches on the activation module can be used to specify the wet threshold (sensitivity to water discharge) through SW1 and the timer delay (duration before the alarm) through SW2. Scan the QR code for more information.

1. Use the #2 Phillips screwdriver to detach the four screws on the activation module to remove the cover.
2. Locate the valve size in the provided table and use an instrument with a pointed tip to slide the SW1 switches to the positions noted for that size. The wet threshold option values ​​range from 40 (default) to 55 (most sensitive).

Monitor relief valve discharge with smart and connected technology to detect and notify of flooding. The BMS Sensor Connection Kit activates the flood sensor to enable functions that detect flood conditions. The BMS Sensor Retrofit Connection Kit upgrades existing installations by integrating and activating the flood sensor to enable functions for flood detection. When excessive relief valve discharge occurs, the flood sensor energizes a relay signaling flood detection and triggers real-time notification of potential flood conditions through the building management system.

A Note About the Deflector

A properly sized deflector is required when the flood sensor is activated on either new or existing valve installations of Series 009 reduced pressure zone assemblies, sizes ½” to 2″. The deflector helps seat the flood sensor against the backflow valve and direct discharge from the valve. Each deflector is embossed with a positioning indicator to assist installation.

• New valve installation
  The sensor connection kit includes four (4) deflectors marked by size. Select the size designed to fit the backflow relief valve of the installation.
  Remove the flood sensor from the valve then follow procedures in the next two sections to install the deflector with the flood sensor and configure and mount the activation module.

• Existing valve installation
  The following procedures include the deflector with the installation of the sensor connection kit.

Install the Flood Sensor

For Series 009 assemblies, sizes ½” to 2″, attach both the deflector and the flood sensor to the backflow relief valve. For sizes ½” to ¾”, the deflector fits inside the flood sensor. For sizes 1″ to 2″, the deflector fits inside the relief valve.

NOTICE The deflector must be installed for the flood sensor on Series 009, sizes ½” to 2″, to function properly.

Series 009, sizes ½” – ¾”

1. Align the grooves of the deflector with internal ribs of the sensor to insert the deflector inside the flood sensor.
2. Position the flood sensor on the relief valve.
3. Use a #2 Phillips screwdriver to tighten the captive screw.

Series 009, sizes 1″ – 3″; Series 909 Small, sizes ¾” – 2″

1. Align the deflector to fit inside the relief valve. (For Series 009, sizes 1″ to 2″ only. Some sensor connection kits include multiple deflectors. Install the deflector designed specifically for the backflow valve size in use.)
2. Position the flood sensor on the relief valve and insert the two mounting bolts.
3. Tighten the bolts to secure the deflector and the flood sensor. Do not over tighten.
   • For Series 009 sizes 1″ to 1½” and Series 909 Small sizes ¾” to 1″, use a 3⁄16″ Allen wrench.

5. Remove the dust cover from the flood sensor.

6. Press the activation module with cable on to the flood sensor.
   NOTICE Retain the dust cover to protect the flood sensor during temporary instances when the activation module may need to be removed or replaced.

7. Check that the activation module is seated securely on the flood sensor.

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

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.
