Description

STI STI-13220FR Universal Stopper with Horn, Surface Mount

Overview

The STI-13220FR Universal Stopper is a surface-mount protective enclosure designed to safeguard devices like fire alarm pull stations, intercom units, keypads, and emergency buttons from vandalism, accidental damage, dust, and harsh environmental conditions. Its low-profile design meets ADA requirements, making it suitable for public-facing installations where both protection and accessibility are critical. This unit includes a 105 dB horn, providing an audible alert.

Compatibility

This model is engineered to protect a wide range of devices, including most fire alarm pull stations, numeric keypads, intercom stations, emergency buttons, and electrical light switches or outlets. It is designed for interior and exterior use, offering broad application across commercial and industrial settings. The unit is compatible with STI's optional relay output, which requires a 12-24VDC power source.

Installation Notes

The STI-13220FR is designed for surface mounting. The enclosure features threaded openings on the top and bottom for standard 3/4-inch rigid conduit, facilitating secure wiring. It is rated IP56, indicating protection against dust ingress and low-pressure water jets, but not full submersion. Gaskets are included to aid in sealing the unit against the mounting surface.
