Smoke control system and fire fighting linkage control
In a fire control center, transmission information is collected by means of an alarm bus or multi wire system.
Your diagram, the logic diagram of the smoke control system in the basement for the fire control center of the city, first demonstrates his control.Fire control console with pre programmed automatic logic relations, but when someone is on duty, in order to reduce false positives, fire caused unnecessary losses, and the automatic switch switch into manual files. In this way, there is the confirmation procedure, that is, the discrimination of Y.N. When Y, you convert the fire engine to automatic, and when N, you reset the fire engine and return to the initial state.
The fire engine host receives or sends the corresponding instruction, then connects the corresponding fire fighting equipment by the linkage control cabinet, realizes manual, automatic, long-distance control.
From the fire alarm system to the fan control box, it must be connected by cable. Each signal shall be no less than one. And fire smoke evacuation signal. There is also a fire judgment, also from the upwind control box has a set of signals. Connect by cable. Mainly when the host to determine the error, do not start smoke exhaust air supply signal. See design drawings in detail.
