1.Operation of the valve control release on a fixed CO2 system must immediately ______.A.release CO2 to the protected spaceB.secure all mechanical ventilation in the protected spaceC.sound the rig’s general alarm signal for a fireD.sound an alarm in the ballast control room

2.第一组An automatic system usually consists of a control system and an information system. A control system is a system which measures the condition of some entity and, with the information, governs the state of a variable; i.e., speed, temperature, pressure, position, etc. The open-loop system is the simplest form. a control system may assume. It is distinguished from the closed-loop system by the lack of an input which measures the state of the controlled variable; such an input is called a feedback. In modern ships the open-loop system has practically disappeared and the closed-loop system which operates with a feed-back is extensively used. An information system serves the parallel function of monitoring system or plant performance. The monitoring function may serve a number of purposes; specifically it may indicate values of controlled variables to guide remote control operations, warn of off-limit conditions and provide record of performance. In many cases a visual and audible alarm may be provided to warn of off-limit conditions on board ship and, associated with this, the important variables will be recorded on demand. The automatic control system can be more sophisticated by incorporating digital-processing equipment, that is, a computer. This computer is usually fed with signals from all sensors. It scans the values of the sensors and generates alarm signals for off-limit conditions, acting as a super-supervisor. Sometimes, it can even make necessary and take the necessary action to optimize performance without human intervention.The closed-loop system differs from the open-loop system byA.the lack of a feedbackB.the presence of a feed backC.the lack of a computerD.the presence of a computer

3.What alarm is NOT found on an inert gas system ________．A.Low oxygen alarmB.Low pressure alarmC.Scrubber high water level alarmD.Deck seal low water alarm

4.The CO2 flooding system is actuated by a sequence of steps which are ______.A.break glass, pull valve, break glass, pull cylinder controlB.sound evacuation alarm, pull handleC.open bypass valve, break glass, pull handleD.open stop valve, open control valve, trip alarm
