Conditional Response
SWITCH P/MVS
To enable P/MV switching on sensor input, each station in
the aected Flow Zone should be set to call for both P/MV
outputs.
When the sensor is alarmed, or changes position, it should
then be set to “Close P/MV” for the P/MV that is not wanted.
In this way, only one P/MV would be active at any given
moment, because the stations are calling for both of them,
but one is disabled by the sensor input.
Example: There are two points of connection available, one
potable water, and one non-potable. Each has its own Master
Valve. A oat switch is installed to monitor the non-potable
level. All stations are set at Station Setup to call for both
Master Valves.
When the oat switch is closed, it disables the P/MV for the
potable water supply, so only non-potable water is used.
When the oat switch is open, it disables the P/MV for the
non-potable supply, so only potable water is used.
They will not both be disabled at the same time, since only
one position can be in eect at a time.
