How much wattage is the number of watts?
600W or more generally no use, at home open and run long-distance two have been enough to ring, more than 600W belong to a waste of money fever level
This is what you want to use, if you are at home open, get hold with 150W is enough, if you are running long distance with 300W
Private 150W is enough, need to consult with more information please log on alarm siren network = customer service staff of this site will answer your questions for various sirens
