STI STI-V6402WIR4 Wireless Exit Stopper Double Door with Voice Receiver
Overview
The STI-V6402WIR4 is a wireless-enabled exit stopper designed for double-door egress points in commercial security installations. Operating at 9VDC, this unit combines an electromagnetic strike mechanism with an integrated voice receiver for credential-based access verification. The compact footprint (5.375" W × 5.375" H × 2" D) fits standard door frame mounting without requiring extensive structural modification. Deploy this where you need to prevent unauthorized exits while allowing legitimate egress via voice authentication — typical in secure facilities, server rooms, or controlled-access zones where wireless communication is preferred over hardwired strike wiring.
Compatibility
The STI-V6402WIR4 integrates with wireless access control systems supporting voice receiver protocol. Suitable for double-door frame installations where dual egress control is required. Compatible with STI wireless conversion boards and control systems that operate at 9VDC. Verify wireless frequency and protocol compatibility with your access control panel before installation — the voice receiver must pair with your existing system's radio frequency standard to function.
Installation Notes
Requires 9VDC dedicated power supply — plan your power distribution accordingly, as this device does not draw power over communication lines. Unit can be mounted on top, right, left, or adjacent to the door frame depending on installation constraints. Field-selectable settings allow on-site configuration of alarm duration, delay, and volume without returning to the manufacturer. Wireless communication range and multipath performance depend on building material (concrete, steel, and metal studs attenuate RF signal). Test wireless signal strength at the intended mounting location before final installation to avoid communication dropout.
