110V or 220V as appropriate, two (2) sets of
valves and elbows to facilitate the circulation
of the water, a System Sensor vane-type water-
flow detector, and a key switch to activate the
recirculating pump. When activated, the pump
shall circulate the water within the sprinkler
riser around the waterflow detector vane to
simulate the flow of one sprinkler head in oper-
ation. The activating key switch shall provide
the means to be wired locally to one
Zonecheck Flow Switch Tester, or intercon-
nected with other key switches for group
activation. Flow Switch Tester shall be avail-
able for manifold and retrofit installation
applications. Zonecheck Flow Switch Tester
retrofit models shall be listed by Underwriters
Laboratories, Inc.
