The tablet utilized a secured wi-fi connection to ONLY communicate with the paired SAM Control
Center and only one tablet can be paired to the associated SAM Control Center (apparatus). This
allows multiple apparatuses to operate on the same fire scene without undesired tablet interac-
tions and prevents other devices from being connected to the tablet.
Figure 51. SAM Tablet
The tablet is essentially a duplicate of the SAM Control Center in Auto Mode. The operator can
control the active intakes, discharges and tank valves from the tablet (including receiving Warn-
ings or Errors). The tablet is designed to allow freedom of movement around the apparatus
(truck) and allow operator positioning to be the most effective and safe. The tablet is intended to
provide close proximity remote control of the SAM system and is not intended to place the opera-
tor far away from the apparatus (where manual intervention would take additional time).
However, SAM manual control (Manual Mode) is not available from the tablet. If Manual Mode is
needed the operator must return to the apparatus and the SAM Control Center.

SAM Automated Pump Cooling
SAM automatically attempts to prevent the pump from overheating using the auxiliary cooling so-
lenoid and if required the tank fill valve.
The auxiliary cooling solenoid (located on top of the pump in one of the pressure taps) opens
when the onboard water tank is selected. This condition is indicated by the aux cooling icon (ro-
tating orange and green arrows) being displayed on the Pump Controller (superimposed over the
TANK FILL and TANK-TO-PUMP valve position icons) and causes water to be circulated thru the
onboard water tank.
If the pump temperature reaches or exceeds 105 ° F (40° C), SAM automatically opens the
TANK FILL valve to the 30% open position (indicated by the AUTO icon being displayed for the
valve) to further attempt to automatically prevent the pump from overheating. The HIGH PUMP
TEMPERATURE WARNING (see Section 6.3.7, Operator Responses To SAM Alarms, page 106) is
activated.
NOTES
A small onboard water tank circulating water for an extended period may allow the
tank water temperature to rise.
COOLANT TEMPERATURE is used to indicate pump water temperature.
