STI KIT-M05603-R Replacement Lens for SA5600
Overview
The KIT-M05603-R is a red replacement lens assembly for the SA5600-series access control hardware. This component is a direct replacement for damaged, clouded, or faded lens elements in existing door lock and strike installations. Install this when the original lens has deteriorated visibility or physical damage — a cost-effective alternative to full device replacement.
Compatibility
Designed specifically for STI SA5600-series door strikes and locks operating at 9VDC. Verify your existing hardware model matches SA5600 before ordering. This lens is a direct mechanical fit for SA5600 assemblies and does not require controller or firmware changes.
Installation Notes
Replacement is a mechanical swap — remove the old lens from the SA5600 housing and install the new red lens. No wiring changes or reconfiguration needed. Ensure the 9VDC power supply remains stable during swap to avoid strike release. If the SA5600 is wired into an access control panel, power down the lock circuit before removal to prevent accidental door release.
