The Post Indicator Valve (PIV) is located at
the control valve for a fire suppression water sprinkler system.
When a PIV is closed, it
activates and sends a data message to the
fire alarm system control panel for processing. When the PIV is open,
it resets and sends a data message to the
control panel, indicating that it is in a normal condition.
Users see status and alarms from the sensor at
keypad. The control panel can also send a message to the monitoring
Reasons to Choose this Sensor
The Serial Interface Module makes any PIV
(Post Indicator Valve) addressable, so it can separately supervise one or
more devices simultaneously, while providing individual identification on
system user interfaces, and at the monitoring station.
It minimizes the need for additional power
supplies because of its low current draw.
Monitoring a PIV is ideal, and usually
required for any fire suppression sprinkler system.
