R  A. Test: 

R R R R  (1) - Open the circuit breakers 11WQ and 12WQ - Wait 20 seconds - Close the circuit breakers and wait again 1 minute before start of the next test.
 (2) Do the operational test of the lavatory smoke-detection system (Ref. AMM TASK 26-17-00-710-001).
 4. Fault Isolation_______________ 
R R R A. If the test gives a different maintenance message: - Do the trouble shooting procedure related to the maintenance message. 
B. If the test gives the maintenance message TEST OK, no other maintenance action is necessary.

 C. If the test gives the maintenance message SMOKE DET LAV X (YWQ):
 NOTE : X/Y shows the related lavatory location.

____

 - replace the related lavatory smoke detector (Ref. AMM TASK 26-17-15-000-001) and (Ref. AMM TASK 26-17-15-400-001).
