Local building or plumbing codes may require modifications to
the information provided. You are required to consult the
local building and plumbing codes prior to installation.
If the information provided here is not consistent with

Need for Periodic Inspection/Maintenance: This product
must be tested periodically in compliance with local codes,
but at least once per year or more as service conditions war-
rant. If installed on a fi re suppression system, all mechanical
checks, such as alarms and backflow preventers, should be
fl ow tested and inspected in accordance with NFPA 13 and/
or NFPA 25. All products must be retested once maintenance
has been performed. Corrosive water conditions, and/or
unauthorized adjustments or repair could render the product
ineffective for the service intended. Regular checking and
cleaning of the product's internal components helps assure
maximum life and proper product function.
Do not impede or prevent sleeve movement by installing riser
cradle clamps or other obstructive elements on or around the
sleeve. Sleeve movement is required to service the backflow.
NOTICE
For Australia and New Zealand, line strainers should be installed
between the upstream shutoff valve and the inlet of the backflow
preventer.
C400-OSY with supervisory switches and flood sensor
Series C400, C500, and LFC500 each include a flood sensor on
the relief valve to detect excessive discharge and trigger notification
of potential flood events. To provide protection against fire,
the series also include the option for an integrated supervisory
switch on the OS&Y gate valve to signal when the water supply
to the sprinkler system is being either tampered with or shut off.
NOTICE
An add-on connection kit is required to activate the flood sensor.
Without the connection kit, the sensor is a passive component
that does not communicate with any other device. (A retrofit
sensor connection kit is also available for existing installations. See
"Add-on and Retrofit Sensor Connection Kits," for ordering details.)
NOTICE
Use of the flood sensor does not replace the need to comply
with all required instructions, codes, and regulations related
to installation, operation, and maintenance of this product,
including the need to provide proper drainage in the event of
a discharge.
