Is the fire alarm linkage switch automatic or manual?
I figured out the meaning of this problem, is that the fire control equipment is usually in manual or automatic state, is two choose a topic
The answer is in the automatic, because a lot of equipment there is a linkage relationship, only in order to achieve this state of automatic transport, reach the purpose of system design (of course, a lot of units because of fear of misoperation before playing in the manual, but this does not meet the requirements of specification, high value class staff also put forward quality).
