STI STI-6402WIR Wireless Exit Stopper Door Alarm for Double Door
Overview
The STI-6402WIR is a wireless-enabled door alarm designed to prevent unauthorized exits and entries on double-door installations. Operating on 9 VDC, it combines hardwired connectivity with wireless transmission capability — a practical retrofit option for existing security systems that need mixed-mode door monitoring without replacing door hardware. Mounts on top, left, right, or adjacent to the frame, making it less costly and less intrusive than traditional horizontal bar units while maintaining perimeter control on emergency doors.
Compatibility
Designed for standard double-door frame installations. Integrates with security systems supporting wireless door monitoring and hardwired annunciator or alarm integration. The dual-mode (wired + wireless) architecture allows deployment in facilities with both legacy hardwired panels and wireless expansion requirements.
Installation Notes
Mounting locations: top, left, right, or adjacent to door frame. Requires 9 VDC power source — verify your control panel or power supply can deliver this voltage to the alarm terminal strip. User-configurable on-site settings for volume, alarm duration, and entry delay — no field reprogramming of the wireless module required. Contact the manufacturer for custom applications or non-standard door configurations.
