Emergency doors serve a critical purpose, but unauthorized access can compromise safety and security. The STI-6400 Exit Stopper provides a reliable solution to protect your business, facility, or organization from unwanted entries or exits through emergency exits.
When someone opens the protected door, this alarm emits an ear-piercing 105 dB warning horn that draws immediate attention. That's louder than most power tools and similar to the sound of a car horn right beside you—impossible to ignore in any environment. You can choose from three alarm durations: 30 seconds for quick alerts, 3 minutes for persistent warnings, or continuous mode for maximum security.
The Exit Stopper doesn't just sound alarms—it gives you control. The key-operated override allows authorized personnel to silence the alarm and exit when needed. For quieter environments, use the annunciator mode, which announces door opening with a series of 10 beeps before resetting automatically. This versatility makes it perfect for offices, schools, retail stores, healthcare facilities, and any location where emergency door security is important.
Mounting this security device is straightforward—simply attach it to the top, right, left, or beside almost any door using the included hardware. The highly visible "stop sign" design serves as an effective deterrent even before anyone attempts to open the door. Powered by a long-life 9-volt alkaline battery, it's completely self-contained and requires minimal maintenance. Available in red or green to match your facility's color scheme and installation requirements.
Backed by a 3-year guarantee against polycarbonate breakage and 1-year coverage on electronic components, this alarm system delivers reliable security when it matters most. Protect your property, your people, and your peace of mind with the STI-6400 Exit Stopper.
