STI KIT-AP2100-YZA Concise Descriptor

Overview

The STI KIT-AP2100-YZA is a yellow, notched replacement shell designed for the STI Stopper® Station series, specifically the Stopper II and Weather Stopper II models. This protective cover fits over manual fire alarm call points and similar devices, shielding them from environmental factors like rain, dust, and extreme temperatures, as well as preventing accidental or malicious operation. Its bright yellow color also serves as a visual deterrent and aids in quick identification in emergency situations. The design ensures legitimate access to the device is not restricted during an actual emergency.

Compatibility

This replacement shell is engineered for use with the STI Stopper II (STI-1250 & STI-3150) and Weather Stopper II models. It is designed to fit over manual call points and other larger, weather-exposed devices that require protection.

Installation Notes

Installation involves positioning the frame over the device to be protected and marking four fixing hole locations. Drilling is required using a 7mm masonry drill bit. The frame is then secured with the provided screws. For Weather Stopper II installations, a weather gasket is positioned over the device before securing the frame. For surface installations, inserts are used to blank off unused cable entry holes, and an appropriate cable gasket should be selected for the wiring system.
