 4. Procedure
_________
 Subtask 26-17-00-720-051
 A. Test of the Lavatory Smoke-Detector Sensitivity (ionization type
 smoke-detector)

 NOTE : The voltage is between 6 and 6.5 V DC when the SDCU does an
____ automatic test of the smoke detectors. The sensitivity check must be done after approximately 10 seconds, with the detector in stand-by condition.
 (1) Do this test.
 -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the test plug assembly: On the multimeter:
 -read the voltage shown on the multimeter. - the voltage is between 4 and 5 V DC.
