STI STI-6602 Replacement Horn Kit
Overview
The STI-6602 is a replacement horn assembly for the STI-13000 Universal Stopper electric strike series. This accessory is installed when the integrated sounder requires replacement due to wear, damage, or component failure — a common maintenance scenario in door access control systems subject to repeated alarm cycles. Operating at 9VDC, it integrates directly into existing STI-13000 installations without additional power infrastructure or system reconfiguration.
Compatibility
The STI-6602 is compatible exclusively with the STI-13000 Universal Stopper series electric strikes. Verify your installed strike model before ordering — this kit will not retrofit other STI strike families or third-party systems. Installation fits within the sounder cavity of the STI-13000 frame, making it suitable for retrofit applications where the original horn has failed or requires upgrade.
Installation Notes
Horn replacement requires removal of the existing sounder assembly from the STI-13000 frame. Power down the strike system before beginning work. Secure the replacement horn unit into the sounder cavity using the mounting provisions integrated into the STI-13000 housing — no additional brackets or adapters are required. Reconnect the 9VDC wiring harness to the horn terminals, matching polarity. Test alarm activation before restoring the system to service. If the strike operates within an access control system or integrated fire alarm interface, confirm the replacement horn meets any decibel or tone requirements specified in your system design documentation.
