Description
• The Series LFF113FP Wireless Smart Universal Flood
Protection ACV System with SentryPlus Alert™ Technology
detects continuous water discharge from a Reduced Pressure
Zone (RPZ) Backflow Preventer and shuts down the valve in
case of abnormality.
• SentryPlus Alert wirelessly alerts the user of the problem via
text, call, or email.
• The system is installed upstream of the RPZ Backflow
Preventer with the valve normally open. It closes when continuous discharge from the RPZ Relief Valve is sensed or by
engaging the Solenoid Bypass.
• The Position Indicator provides local visual indication of valve
closure.
• The valve is reset manually. Pressure Gauge (provided) indicates valve reset for automatic service.
• Reverse Flow Main Valve closes in the event of diaphragm failure for fail-safe operation.
• The Junction Box is pre-mounted to the valve body, but can
be mounted remotely in field.
• The Flow Sensor and the SentryPlus Alert Wireless Node both
require field installation.

Installing the Wireless Node
!
WARNING
Ensure all power supply to the Wireless Node is turned
off before making any connections to the Wireless Node.
Failure to do so may result in electrocution, personal
injury, and/or death.
1. Identify preferred location for mounting Wireless Node. The
Wireless Node must be located away from large metal components and structures that may block the cellular signal. In
addition, the cellular antenna is located on the inner sidewall
of the enclosure (11). When mounting, ensure that this side
of the device is away from any walls, wires, pipes, or other
obstructions, especially anything metallic.
2. Before mounting, plug in the Wireless Node to ensure that
a connection can be made in the preferred location. Once
plugged in, the device will automatically go through a startup process. A cellular connection has been made if, after the
start-up process, the Cellular LED (8) is a steady blue. If it is
blinking, there is a poor connection, and if it is off, there is
no connection. If there is a poor or no connection, identify a
new location for mounting.
3. Unplug the Wireless Node from the power supply.
4. Mount the Wireless Node in the identified location using the
four 0.27" diameter mounting holes (13). Screws are not
included.
5. Route wires from terminals 7 and 8 of the Junction Box
through the wiring gland (12) and connect to the Wireless
Node at the “Flood” screw terminal (2). Polarity does not
matter. Six feet of wire is supplied with the unit, but the
Wireless Node can be located up to 100 feet away from
the Junction Box. If additional wire is used. it must meet the
required rating for the Junction Box (300V, 16-24 AWG).
6. Route wires for included 12VDC power supply through the
wiring gland (12) and connect to the Wireless Node at the
appropriate screw terminal (1). Polarity must be correct or
the Wireless Node will not operate.

Start-up Instructions
Proper Automatic Control Valve start-up requires bringing the
valve into service in a controlled manner. All adjustments to control pilots and speed controls should be made slowly, allowing
the valve to respond and the system to stabilize. NOTE: Control
Valves should be set up in a dynamic (flowing) condition for
proper start-up. Provisions for flow must be made to ensure
proper settings.
NOTE: Refer to valve schematic on page 3 for components
identified in parentheses.
4. Close Solenoid Bypass Valve and open Manual Reset Ball
Valve. Pilot System Pressure Gauge will drop to zero. Valve
will open fully and is ready for electrical activation. Allow for
cover volume to discharge to floor drain. Refer to the chart
below for Valve Cover Chamber Capacity. Close Manual

Maintenance
We recommend establishing a periodic maintenance schedule to
inspect the ACV’s valve stem for calcium or hard water deposits
and to check the condition of the diaphragm, seat disc, strainers, and port openings.
An annual preventative maintenance schedule can help to identify potential problem situations before emergency repairs are
needed.
For more severe service, semi-annual or quarterly inspections
may be required.
The normal replacement parts are the seat disc and diaphragm.
These are available individually or together in a rubber repair kit.
Rubber repair kits for control pilots are sold separately.
For maximum life expectancy, all rubber repair parts should be
stored in a cool, dry environment and not be exposed to direct
sunlight.
In the event a non-rubber component part is required, review the
cross-sectional drawing in the product specification sheet and
consult your local representative or the factory.
