Important Information
•
Zonecheck Retrofit should be installed by a competent fire sprinkler installer and wired
up by a qualified electrician.
•
Ensure Zonecheck Retrofit 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 Retrofit could be activated 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. This is 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 (optional, see group testing) is adjacent
to the fire alarm panel.
•
Fix operating instructions to wall, preferably next to key-switch.
•
Each Zonecheck Retrofit 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.
