Storage
Functional Description —The LIFEPAK 9 shock advisory adapter contains a SAS Adapter PCB, a amy
High Voltage Connector Cable Assembly, a Pushbutton Switch Wire /
Harness, and two Test Load Wire harnesses. The Functional Block
Diagram in Figure 1-3 illustrates the main functions of the instrument.
Power for the adapter is supplied by the SW BATT line from the Power
Conversion PCB in the defibrillator/monitor. Four separate voltages are
generated by the Power Supply circuit on the SAS Adapter PCB from
SW BATT.
During ECG analysis, the FAST-PATCH disposable defibrillation
electrodes capture incoming patient ECG. The Preamp circuit conditions
the ECG signal for sampling by the microcontroller in the
Microcontroller Core circuit. Pressing ANALYZE on the front panel stores
sampled data into this circuit, otherwise data is not saved. The
Microcontroller Inhibit circuit shuts down the Power Supply circuit to
protect the microcontroller from transient voltages.
Commands from the adapter front panel are isolated by the Instrument
Interface circuit. Serial communication between the microcontroller and
the Power Conversion PCB in the defibrillator/monitor is also isolated by
the Instrument Interface circuit.
