The STI STI-6400 is the Exit Stopper Multifunction Door Alarm for single doors, in red with white "Stop / Alarm Will Sound" graphics. First, the unit mounts beside the door with the supplied reed switch on the frame. Then, when the door opens, the alarm flashes and sounds. As a result, the STI-6400 deters unauthorized exits and reports door activity.
What the STI STI-6400 is built for
Side exits, stairwells, and back-of-house doors are common targets for theft and policy violations. However, hard-wiring an alarm at every door is expensive. Therefore, the battery-powered STI-6400 mounts in minutes and runs without panel integration.

When the STI STI-6400 is the right choice
Specifically, the STI-6400 fits single-door applications where the goal is deterrence, not panel integration. For example, retail back doors and clinic side exits. In addition, the annunciator mode also works as a door-chime for staff stations.
Application context
The STI-6400 is a stand-alone device and is not a UL-listed fire alarm signal. Therefore, do not substitute it for code-required notification appliances. Also note: the housing is indoor-only and should not be exposed to water.
