STI Door Alarm is Easy to Install

STI’s newly redesigned exit stopper door alarm - SDM Magazine

STI’s newly redesigned exit stopper door alarm now flashes while it emits an audible alarm, helping to further deter wrongful use of a protected door. STI-6400 is easy to install and the stop sign shape helps deter misuse. When activated, it sounds a warning alarm and now includes a flashing LED. User selects on location the ear-piercing alarm volume and length (30 sec., 3 min. or continuous). Another option is annunciator mode. In this mode the alarm will beep several times and reset when the door is closed. When used in alarm mode, a key-operated override will silence the alarm and allow authorized exits. For indoor use only.
