Stopper Emits Ear-Piercing Alarm

STI’s Exit Stopper helps solve the problems related to unauthorized exits and entries of fire or emergency doors while increasing workplace security with this multifunction door alarm. If a protected door is opened, the STI-6400 emits an ear-piercing alarm for 30 sec., 3 min. or continuously as preset by the user. Annunciator mode announces door entry/exit with two beeps repeated five times at 95 or105dB. When the alarm is used in alarm mode, a key-operated override will silence the alarm, allowing authorized exits through the door.
