STI STI-V6400WIR4 Wireless Exit Stopper with Voice Receiver

Overview

The STI-V6400WIR4 is a wireless exit stopper designed to prevent unauthorized egress while integrating audio feedback into your access control workflow. Operating at 9VDC, it mounts flush to door frames and pairs with wireless control systems to enforce exit delay or full stopper lockdown without hardwired power or alarm runs. The on-site configurable alarm—selectable between audible alarm or silent annunciator mode—lets you tune responses per door risk profile without firmware updates.

Compatibility

The STI-V6400WIR4 integrates with access control systems that support wireless exit stopper peripherals and require audio feedback or alarm annunciation. Verify wireless protocol compatibility (2.4 GHz or proprietary STI wireless) with your controller or wireless conversion board before deployment. Compatible with standard access control door frames where alarm or voice receiver feedback is required for exit delay enforcement or emergency egress monitoring.

Installation Notes

Mount on top, right, left, or adjacent to door frame using provided bracket options—no modification to existing hardware required. The unit draws 9VDC only (no separate transformer needed if your system provides wireless-powered auxiliary supply). Set alarm volume, duration, and delay via on-board circuit board switch configuration before installation; no field reconfiguration without opening the housing. Polycarbonate construction rated for standard indoor commercial environments; avoid direct moisture exposure or extreme temperature swings. Consult STI technical support for non-standard door types or custom mounting scenarios.
