When retrofitting an existing Model 113RFP Flood Protection ACV,
disconnect the electrical power before retrofitting the old Junction
Box to the new one.

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.
