STI-1200A-HTR Stopper Ii Heated Pull Station Cover Enclosure

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-1200A-HTR is a heated protective enclosure designed to shield manual pull stations from accidental activation, vandalism, and environmental conditions. The unit includes a 4 inch deep back box, providing the mounting depth needed to accommodate a variety of pull station devices. The integrated heater prevents fogging, condensation, and freeze-related issues that can compromise pull station performance in cold or high-humidity environments. This enclosure is installed by fire alarm technicians and electricians working on life-safety systems in commercial, industrial, and institutional settings.

The STI-1200A-HTR is suited for indoor and outdoor applications where pull stations require environmental protection without sacrificing accessibility or code compliance. The deep back box version accommodates pull stations with greater housing depth, making it a practical fit for retrofit and new-construction projects where standard-depth covers fall short. Typical installations include warehouses, parking structures, cold-storage facilities, and covered outdoor areas subject to temperature extremes or moisture exposure.
