8' 4-conductor cable
B. Cellular Gateway with
mounting hardware
Requirements
• 1/2" Wrench for flood sensor size 21/2" to 3" or
for flood sensor size 4" to 10" (retrofit installation only)
• #2 Phillips screwdriver
• Wire stripper
• A suitable location within 8 feet of the flood sensor for
mounting the Cellular Gateway on a wall or structure,
Installing the Flood Sensor
NOTICE
Only for existing installations of the backflow preventer
without the flood sensor.
Lay out the flood sensor, O-ring, mounting bolts, and wrench
for this segment of the installation.
1. Insert the O-ring into the groove on the top of the
flood sensor.
2. Use the two mounting bolts to attach the flood sensor to
the relief valve.
If an air gap is attached, use the mounting bolts to install
the flood sensor between the relief port of the backflow
valve and the air gap.
3. Use the wrench to tighten the bolts up to 120 in-lb (10 ft-lb).
Do not overtighten.
NOTICE
The connection kits are suitable only for new or existing
installations of the specified valve assemblies.
C. 24V Power adapter (requires a
120VAC, 60Hz, GFI-protected
electrical outlet)
D. Included in the retrofit kit
only: Flood Sensor, size
21/2" to 3" or size 4" to 10"

NOTICE
Retain the dust cover to protect the flood sensor during
temporary instances when the activation module may need
to be removed or replaced.
Custom Flood Sensor Settings
DIP switches on the activation module
can be used to specify the wet threshold
(sensitivity to water discharge) and the
timer delay (duration before alarm). Scan
the QR code for more information.
Mounting the Activation Module
The activation module receives a signal from the flood sensor
when a discharge is detected. If the discharge meets the con-
ditions of a qualifying event, the normally open contact is closed
to provide a signal to the Cellular Gateway input terminal.
1. Use the Phillips screw-
driver to remove the
dust cover from the
flood sensor.
2. Remove the O-ring
from the cover and
place it on the activa-
tion module to create
a seal between the
module and the
flood sensor.
3. Attach the activation
module to the flood
sensor with the four attachment screws.
