Addressable fire alarm systems

The code here refers to the preparation of theaddress code. As we know, in a fire system, each detector, sound & lightalarm, manual alarm are corresponding to a point, and the addressable detector wouldgive a code to every point trough the address code encoder, different codescorresponding to different monitoring areas, thus, when fires happen, the firealarm panel would receive the code information, and could quickly recognizewhich detector sent out the alarm, and help human to find the fire places.While the non-addressable detectors can’t give codes to the points, if we wantto recognize which detector sent the alarm, we have to connect the detectorwith a fire alarm model, and connect the model to the panel.
