NOTE: To allow for automatic or
remote starting (e.g. by SMS) the
keystart must be left in the “ON”
position. Operation via SMS is only
possible where your pump Remote/
Auto Control Centre is within
reception range.
WARNING: Always disconnect battery
from engine prior to working on pump,
engine, or controller. Turning the key
start switch to “OFF” may allow a
remote start signal to enable engine
“cranking”, but not starting.
The black battery lead should be
connected to the negative terminal
(-ve) on the battery. Only once ready,
including after all necessary external
wiring connections are complete,
should the red lead be connected to the
positive terminal (+ve) on the battery.
Fire sensors: (Davey part number 402939). These
must be connected in series. The looped wiring is
connected to the Fire Sensor (NC) terminal and the
adjacent “GND“ terminal inside the Remote/Auto
Control Centre. The bridging wire included must be
removed if the fire sensors are installed.
The wire used to connect the sensors should be
suitable for extra low voltage usage in the outside.
Wiring such as is used for automatic irrigation
control valves is ideally suited. Sizes 7/0.30 or
7/0.43 are more than sufficient for the purpose.
These should be protected from damage as an
open circuit (e.g. broken or cut wire) will result in
automatic pump start.
Sensors should be mounted on the edges of the
building or the property to be protected every 10
to 20 metres. The connecting wire must be in one
continuous loop.

Once the pump is started via Fire Sensor it can only
be stopped via manual stopping (Turn the key to
“off”) or an SMS command to “stop” or the pump has
run out of fuel / oil alert shut down.
Emergency Switch or Button: These are used for
localised remote starting via a normally open push
button or switch. This is not an “on/off” switch, only
an “on” switch.

Figure 7.6
Once the pump is started via Emergency Switch or
Button it can only be stopped via manual stopping
(Turn the key to “off”) or and SMS command to “stop”
or the pump has run out of fuel / oil alert shut down.
Flow/Pressure LOP Switch: This function allows for
a flow or pressure switch to be connected to detect
correct operation and shut down in the event of
closed head (flow switch option only) or loss of prime
(no flow or no pressure dependant on sensor used).
This option works best with a basic flow switch,
as the initiation time delay of 4 minutes is built in
allowing for a pump to gain prime (manual or SMS).
Once the pump is running LOP is also tied to a shut
down in the event of no flow after 30 seconds.
