Safety Technology Intl STI-1102 Replacement Horn Stopper Ii

Product Description

The Safety Technology International STI-1102 is a replacement Horn Stopper II cover designed to protect pull station devices from accidental or unauthorized activation. This cover fits over existing pull stations and provides a physical deterrent against unintentional alarm pulls. When the cover is lifted or displaced, an integral local horn sounds an audible alert, notifying nearby personnel of tampering or unintended contact. The STI-1102 is installed by fire alarm technicians, electricians, and building maintenance professionals in commercial and institutional facilities where false alarm reduction is a priority.

The STI-1102 is suited for commercial, institutional, and light industrial environments where pull station protection is required. Typical installation locations include schools, hospitals, office buildings, and other facilities where high foot traffic increases the risk of accidental or malicious alarm activation. The cover is a direct replacement unit intended to restore an existing Horn Stopper II installation to full working condition without replacing the entire assembly.

Ensure the replacement cover is properly seated and secured before restoring power to the circuit. Verify audible horn function after installation is complete.
