STI’s Exit Stopper continues to help solve the problems of unauthorized exits and entries of fire or emergency doors. The multi-function door alarm is excellent in helping increase workplace security. The highly effective Exit Stopper (STI-6400) alerts if a protected door is opened by emitting an ear-piercing alarm for 30 sec., 3 min., or continuously (as preset by the user). Another option is annunciator mode (loud 95 dB or 105 dB). In this mode it announces door entry/exit with two beeps repeated five times. When used in alarm mode, a key-operated override will silence the alarm and allow authorized exits through the door. The alarm can serve as an inexpensive workplace security device and help stop theft as well.
