STI 6404 Exit Stopper for Double Door with Remote Horn, Red

  • MPN: 6404
  • JMAC ID: 200061622
Highly effective, alarm alerts you to any unauthorized exits/entries through emergency exits with double doors. Serves as an inexpensive security device and helps stop theft as well.

If the protected doors are opened, the electronic Exit Stopper (STI 6404) emits an ear piercing alarm from the main unit and remote horn for 30 seconds, three minutes or continuously (as preset by the user). A key operated override will silence the alarms and allow authorized exits. Another option is annunciator mode, in this mode it announces a doors opening with a set of 10 beeps and then resets. Exit Stopper is fitted with a long life 9-VDC alkaline battery. It is available in red or green for almost any type of door, mounting or installation.
