Nurse Call Relay Test
Patient Leakage Current With Mains Voltage Testing
Figure 3-6 S(3) Patient Leakage Current, Single Fault Condition (S.F.C.) Mains on an
Applied Part
Expected Test Results:
Maximum leakage current, x 50A @ 250V (IEC60601-1 and ES 60601-1)
Measures patient leakage current from applied part to earth caused by external main
voltage on applied part. Each polarity combination possible is tested using S2 and S6.
This test is applicable for each applied part in turn.
Note — To test the patient leakage current of the Mainstream CO
2
connector, if
present, connect the cable to the monitor. Wrap the sensor with foil and
connect it to the safety test equipment. Then test the Mainstream CO
2
as an
applied part.
Nurse Call Relay Test
If your facility uses the nurse call function on the monitor, perform the following
procedure to test the nurse call alarm output relay.
The nurse call alarm output in the monitor uses a phone jack connector tip or ring and
is capable of both normally closed and normally open relay operation.
The nurse call connector jack has three contacts that connect with those on a phono
connector as shown in the following illustration.
