STI Stopper II® with Horn Flush Mount Fire Label - STI-1100

STI STI-1100 Stopper II Horn Flush Mount Fire Label

Overview

The STI-1100 is a flush-mount audible horn designed for fire alarm circuits and access control system integration in commercial and institutional facilities. It delivers emergency egress signaling at monitored exits, fire panels, and access control checkpoints where simultaneous visual and audible notification is required by code. The fire label marking indicates compliance with emergency signaling standards, making it suitable for healthcare, hospitality, and regulated industrial environments where emergency response documentation is critical to facility compliance.

Compatibility

The STI-1100 integrates with standard 7VDC fire alarm and access control systems. It is compatible with door control panels, fire notification appliances, and annunciators that provide auxiliary horn outputs rated at 7VDC. Before installation, verify your fire panel or access control system documentation confirms horn output availability and voltage rating—mismatched voltage will prevent reliable operation. Consult your fire alarm technician to confirm horn circuit integration and program activation sequences into your facility's emergency response logic.

Installation Notes

Operating voltage is 7VDC—confirm your control panel or relay output matches this specification before wiring. Flush mounting requires a standard electrical box or recessed cavity in the door frame or wall adjacent to the monitored exit. Install per your facility's fire code and ADA egress requirements. Coordinate wiring with your fire alarm technician to ensure horn activation is properly programmed, tested, and documented as part of your facility's emergency notification system.
