Important Information
• 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, 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.
