Multifunction Door Alarm
STI’s Exit Stopper continues to help solve the problems of unauthorized exits and entries of fire or emergency
doors. The Exit Stopper (STI-6400) alerts if a protected door is opened by emitting an ear-piercing alarm for 30 seconds, three minutes or continuously (as preset by the user). Sound intensity choices include 95 or 105 dB. The polycarbonate housing is backed by a three-year guarantee against breakage in normal use and one year on electromechanical and electronic components.
