1. Installing the Flood Sensor
(Backflow RPZ Upgrades)
The Flood Sensor is installed in the discharge piping from the
RPZ relief valve. If the Flood Sensor detects water in the dis-
charge piping, it will signal the Control Box to close the valve.
1. Identify a location to mount the Flood Sensor. It can be
installed in either a 2" female NPT joint of your choice, or the
2" NPT tee included with the kit.
2. When using the supplied tee, install the sensor in the RPZ
discharge line in the HORIZONTAL position. Install the Flood
Sensor into the tee by screwing it in, ensuring that the
probes point downward as shown below.
3. Unscrew the black cap to access the sensor probes. Push
the two metal probes down until they touch the bottom of
the pipe, then pull them up at least ¼". The ends of the
sensor probes should be located between ¼" and ½ of
the pipe’s inner diameter from the pipe bottom. The probes
MUST NOT BE less than ¼" from the pipe wall. Hand
tighten the white plastic nuts on the probes to make it
water tight.
Ensure Flood Sensor probes do not contact pipe bottom or sides.

Installation and Operation
WARNING
!
Ensure that all power supply to the Control Box is turned
off before making any connections to the Control Box.
Failure to do so may result in electrocution, personal
injury, and /or death.
WARNING
!
Certified electrician to connect 110 VAC power and Control Box to
Relay Box.
NOTICE
During the retrofitting process on the 113RFP, the system
will not be monitoring for flood detection or protection..
NOTICE
For All Installations
The Control Box is designed to be mounted to a wall using the
mounting tabs and screws provided with the kit, or it can be
mounted on the ACV.
1. To open the Control Box, loosen the four screws located
on the corners of its cover to access the internals of the
Control Box.
2. Use a 300V, 14-24 AWG cable (not provided) to connect
the Flood Sensor to the Control Box. Insert one end of the
cable into wiring gland on the Control Box and attach two
wires to the terminals labeled FLOOD SENSOR. There is
no polarity.
3. Inset the other end of the cable into the opening on the
Flood Sensor. Attach one wire to each terminal block locat-
ed at the top of the probes. There is no polarity.
4. Optionally, use a cable to connect to a Building
Management System or alarm for remote indications of
a continuous water discharge at the terminals labeled
REMOTE TRIP. There is no polarity.
5. Using the four-conductor communications cable with the
kit, connect to the Cellular Gateway using the terminals
labeled WIRELESS. Insert the cable through the wiring
gland and attach one wire to each terminal. Cellular
Gateway connections will be described in the next section,
Installing the Cellular Gateway.
Adjusting the Time Delay
The Flood Sensor has a delay feature which starts a timer once
it detects water. The timer counts down before signaling that
there’s a discharge occurring. You can adjust the time delay to
avoid having the valve close due to intermittent or nuisance relief
valve discharge. The delay is adjustable from 0 to 120 seconds,
and the default is 60 seconds.
Adjust the time delay by pressing the + or - button in the Control
Box.
We recommend setting the delay between 3-60 seconds.
However, the ideal set point can vary widely depending on the
product application, including drain size, location, backflow
preventer, water pressure, and tolerance for discharge. For
example, if your backflow preventer releases water each time a
booster pump turns on upstream and you know it will release
water for 10 seconds before the system stabilizes, you can set
the time delay to 15 seconds.
• The terminal block accepts 14 to 24 AWG.
• Relay Box terminals have 24VDC/AC, 2A max.
• The Control Box uses an external 24VDC, 1.04A, 25W
supply. This also powers the Cellular Gateway.
• The Sensor Probe is passive.

Installation and Operation
For New and Existing LFF113RFP ACV Installations
For convenience, new LFF113RFP ACVs are shipped with a
Solenoid prewired to the Relay Box. Retrofitting an existing
LFF113RFP requires an electrician to make that connection
manually. New and existing ACV systems both require wiring to
the Relay Box.
For Existing LFF113RFP Installations Only
1. After removing power from the circuit, disengage the wiring
from the main terminals inside existing Control Box:
• Terminals 1 and 2 (Flood Sensor)
• Terminals 3 and 4 (Solenoid)
• Terminals 5 and 6 (Remote Trip Indicator, if wired)
2. Remove the Control Box from the ACV or wall mount.
3. Replace the existing control box and mounting bracket with
the new Relay box and mounting bracket.
4. Using the cable from Solenoid, connect the Solenoid to the
Relay Box. Attach the cable to the terminals 5 and 6 in the
Relay Box. There is no polarity.
5. The Relay Box includes several spare terminals for your con-
venience to ease wiring requirements, such as building moni-
toring inputs or valve positioning.
For New and Existing LFF113RFP Installations
1. Using an electrical cable (not provided), connect terminals 3
and 4 in the Relay Box to 110VAC power.
2. Using a 300 V, 14-24 AWG cable (not provided), connect the
Relay Box to the Control Box. Attach one end of the cable
to terminals 7 and 8 in the Relay Box. Attach the other end
of the cable to the terminals labeled ACV in the Control Box.
Connect Terminal 7 to ACV+. Connect Terminal 8 to ACV-.
Solenoid Operation
The Solenoid is equipped with a Solenoid Bypass Valve (nor-
mally closed) which manually
closes the Main Valve when
engaged.
Opening the Solenoid Bypass
Valve pressurizes the Main
Valve cover as indicated by a
pressure gauge, closing the
Main Valve.
Closing the Solenoid Bypass
Valve and opening the Manual
Reset Ball Valve returns the
Main Valve to the full open
position.
The pressure gauge returns to
zero when the Main Valve is
fully open.
NOTE: Manual Reset Ball Valve must be closed for normal oper-
ation.
