Important
Please Read Carefully And Save
This instruction manual contains important information about the instal-
lation and operation of a Zonecheck Flow Switch Tester. Purchasers who
install waterflow detectors for use by others must leave this manual or a
copy of it with the user.
Read all instructions carefully before beginning. Follow only those instruc-
tions that apply to the model you are installing.
Use Zonecheck Flow Switch Testers in wet-pipe systems only. Do NOT use
them in dry pipe, deluge, or preaction systems.
Do not use in potentially explosive atmospheres. Do not allow unused
wires to remain exposed.
Principles Of Operation
Retrofit Model
Zonecheck Flow Switch Tester shall mount on any clear steel pipe span of
the appropriate nominal size, either in a vertical upflow or horizontal run,
between 6″ and 12″ from the flow switch. Flow Switch Tester shall consist
of a recirculating pump, operating at nominal 110V or 220V as appropriate,
two (2) sets of valves and elbows to facilitate the circulation of the water,
a System Sensor vane-type waterflow 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 operation. The activating key switch shall
provide the means to be wired locally to one Flow Switch Tester, or inter-
connected with other key switches for group activation. Flow Switch Tester
shall be available for manifold and retrofit installation applications.
Manifold Model Specifications
Zonecheck Flow Switch Tester manifold models shall consist of a sched-
ule 10 pipe assembly of the appropriate nominal size. Manifold assembly
