STI STI-6400WIR Wireless Exit Stopper Multifunction Door Alarm
Overview
The STI-6400WIR is a wireless-enabled exit stopper and multifunction door alarm designed to prevent unauthorized exits and entries without the cost and installation complexity of a hardwired electric strike. Operating on 9VDC, the unit combines alarm and door-control functionality in a compact footprint (5.375" W × 5.375" H × 2" D), making it practical for emergency doors, retail exits, and secure facility perimeters where wireless communication eliminates conduit runs. The on-site selectable alarm or annunciator mode lets you choose whether the device activates a local sounder or triggers a networked alert through your access control system.
Compatibility
The STI-6400WIR integrates with wireless access control platforms and alarm management systems that support door-mounted annunciators or auxiliary outputs. Before procurement, verify wireless protocol compatibility with your access control or alarm system—confirm that the device's wireless module supports your deployment's frequency and communication standard. The unit is compatible with systems requiring multifunction strike operation (door hold, release, and alarm relay) in retrofit or new-build access control environments.
Installation Notes
Mount on top, right, left, or adjacent to standard door frames. The 9VDC power requirement means you'll need a dedicated power supply or integration with a system that provides 9VDC auxiliary power to the wireless conversion board. Verify local fire codes and ADA requirements for emergency exit devices before installation—some jurisdictions restrict alarm-only solutions on certain door types. Consult STI for custom mounting or integration scenarios not covered in standard documentation.
