Refer to the drawing of a valve motor control circuit (see figure below) for a valve that is currently fully open and has a 10-second stroke time.
Note: Limit switch (LS) contacts are shown open regardless of valve position, but relay contacts are shown open/closed according to the standard convention for control circuit drawings.
The operator takes the control switch to CLOSE.
Two seconds later, after verifying the valve is closing, the operator releases the control switch.
Which one of the following describes the valve motor control circuit alarm response after the switch is released?
A. The alarm will continue to actuate for approximately 8 seconds.
B. The alarm will continue to actuate until additional operator action is taken.
C. The alarm will actuate after approximately 8 seconds.
D. The alarm will not actuate until additional operator action is taken.
