Important Information
•
Zonecheck should be installed by a competent fire sprinkler installer and wired up by a
qualified electrician.
•
Ensure Zonecheck is installed both mechanically and electrically commissioned and
tested prior to leaving site.
•
Ensure protection to Zonecheck is employed whenever there is an extended period
from installation to commissioning.
•
If the Zonecheck could be wired when the sprinkler system zone is drained down then
it is vitally important that the Zonecheck red and green valves are left in the closed
position, to ensure the motor is not accidentally run dry and damaged. (Please ensure
the commissioning engineer is aware of the closed Zonecheck valve status).
•
Always use a flat faced wrench for Zonecheck commissioning.
•
The suggested location for the key-switch is at low level for visibility and access.
•
The suggested location for Master key-switch (see group testing) is adjacent to the fire
alarm panel.
•
Fix operating instruction to wall, preferably next to key-switch.
•
Each Zonecheck is factory assembled and tested. Do not attempt to reconfigure.
Tampering will void the warranty.
•
Maximum working pressure - 12 bar (175 psi), test pressure - 18 bar (260 psi).
•
Use Zonecheck flow-switch testers in wet-pipe systems only. Do not use in dry pipe,
deluge, or pre-action systems.
•
Only activate the Zonecheck key-switch when the valves are opened and the sprinkler
system is full.
•
The pump direction-of-flow arrow faces the opposite direction to the system flow.
•
A local monitored zone/isolation valve can be wired to the key-switch for added
functionality. If connected, when the valve is not in the fully open position the key-
switch ‘VALVE FAULT’ LED will illuminate.
