Zonecheck is a remote flow-switch testing device. It works by using a closed loop system that re-circulate water to simulate sprinkler head operation and test the flow-switch without discharging water.
Zonecheck connects into a wet-pipe sprinkler system using two grooved couplings (not included). When fitted correctly, the red and green stripes on the pump are always horizontal. On horizontal runs, the flow-switch must always be on the top of the pipe. For vertical flow applications, only mount Zonecheck where upflow conditions exist.
