Heat-sensitive member envelops glass tube. Breaking member is made as three diametrical screws uniformly arranged from outer surface of ring-shaped heat-sensitive member and facing glass tube by sharpened ends thereof. Glass tube comprises heat-insulation washers having holes for receiving sharpened ends of corresponding screws.EFFECT: increased speed of sprinkler response and improved reliability of sprinkler actuation.2 cl, 5 dwg
