3.0 Installation and Operating Instructions
Original Installation and Operating Instructions
3.1 Sequence of Operation
The Grundfos FireSAFE+ supplies water, usually from a storage tank, via a riser system within
the building to a system of sprinkler heads.
Should the pressure in the sprinkler system decay, through minor leakage, then the FireSAFE+
unit will detect this pressure drop, via inbuilt pressure switches and run the pump to
re- pressurize the system (Jockey Mode). If the pressure switches remain active or re-activate
within a small-time window, then the FireSAFE+ will enter Possible Fire Mode.
Possible Fire Mode runs the pump until it is manually stopped via the restoration of pressure
in the system and the pressing and holding of the Reset button on the front of the cabinet.
If the unit is connected to a Fire Alarm panel, it will send a Fault signal from the FireSAFE+ unit
to the Fire Alarm Panel. During Possible Fire Mode the cooling line is active. This protects the
pump from a potential no flow condition.
Should a sprinkler head activate then the resulting flow in the system will trigger the system
flow switch which will report a flow of water to the FireSAFE+ unit which in turn will put the
pump in Fire Mode. Fire Mode runs the pump until it is manually stopped via the restoration
of pressure in the system, resulting in the end of the flow signal, and the pressing and holding
of the Reset button on the front of the cabinet. If the unit is connected to a Fire Alarm panel, it
will send a Fire signal from the FireSAFE+ unit to the Fire Alarm Panel.
The FireSAFE+ unit also performs an Auto test on a weekly basis to ensure that it is fault free
and the pump is available on demand. During this test the Cooling line valve opens, releasing a
small amount of water, causing a system pressure drop. The controller monitors both pressure
switches and detects the drop in pressure. The controller activates the pump and continues to
monitor. It runs the pump to increase the pressure until it detects the de-activation of both
pressure switches. Upon de-activation of both pressure switches, the pump is stopped, and
the system should be back up to desired pressure. The Auto test result is recorded in the Log
file. A failed Auto test results in the unit flagging a Fault condition.
Auto test can be replicated at any time, Refer to section 3.2
All Controller/Pump activities are logged in the FireSAFE+ units’ memory for extraction via USB
in report formats.
