The smoke detector is installed in the office building and needs to be networked with the property. They can see anomalies from the system in time and locate them accurately. How much will it cost?

I don't know what brand of cigarettes are used in your office building, but 500 cigarettes is really too high. In fact, it is to buy a coded smoke sense, then connect it to the host computer of the property, and finally code and debug it. I don't know what the quotation basis of the property right unit is, but I feel it is black money.

And this kind of cigarette has an address code. After a fire breaks out, the duty room can see the code from the host computer, thus quickly determining the location of the fire.
