Description

STI KIT-M05501-C Select-Alert Replacement Lens Clear

Overview

The STI KIT-M05501-C is a clear, tamper-proof polycarbonate replacement lens designed to protect devices like manual call points from environmental damage, vandalism, and accidental operation. It is specifically intended for use with larger, weather-exposed devices, enhancing their longevity and reliability in demanding conditions. This lens fits over the protected device, providing a robust barrier without impeding legitimate use. The model number KIT-M05501-C is key for identifying this specific protective component.

Compatibility

This replacement lens is designed for use with STI Stopper II and Weather Stopper II protective cover frames. It is intended for larger devices that require robust protection against harsh environments and potential tampering.

Installation Notes

Installation involves positioning the frame over the device, marking and drilling four fixing holes (using a 7mm masonry drill bit), and securing the frame with the provided screws. A weather gasket should be positioned over the device before securing the frame. For surface installations, inserts are provided to blank off unused cable entry holes. Ensure the appropriate cable gasket is selected for the wiring system.
