WARNING
!
Freeze sensor solely provides alerts about a possible freeze
event and cannot prevent a freeze event from occurring.
User action is required to prevent freeze conditions from
causing product and/or property damage.
NOTICE
For Australia and New Zealand, line strainers should be
installed between the upstream shutoff valve and the inlet of
the backflow preventer.
If installed on a fire sprinkler system, all mechanical checks,
such as alarm checks and backflow preventers, should be flow
tested and inspected internally in accordance with NFPA 13
and NFPA 25.

800M4FR-FZ
Series 800M4 and LF800M4 antisiphon PVBs (FR and QT
versions) include a freezer sensor to signal building/irrigation
management systems when temperature nears the freezing point.
NOTICE
An add-on connection kit is required to activate the freeze sensor.
Without the connection kit, the sensor is a passive component
that has no communication with any other device. (The kit can
also be used to retrofit existing installations. See "Add-on/Retrofit
Sensor Connection Kit," for ordering details.)
NOTICE
Use of the freeze sensor and activation kit with FZ models does
not replace the need to comply with all required instructions,
codes, and regulations related to installation, operation, and
maintenance of the PVB assembly.
Watts is not responsible for the failure of alerts due to connectivity
or power issues.
