STI Stopper II® with Horn and Clear Spacer Fire Label - STI-1130

STI STI-1130 Emergency Egress Alarm with Horn and Clear Spacer

Overview

The STI-1130 is a Stopper II® emergency egress alarm configured with integrated horn and clear spacer, fire-rated label. It operates on 28VDC input, making it compatible with standard access control power supplies and building security infrastructure. The clear spacer provides visual indication of alarm status while maintaining a compact wall or surface mounting footprint. Fire-rated labeling ensures compliance with life safety code requirements for emergency egress routes and controlled access points.

Compatibility

The STI-1130 integrates with 28VDC access control systems, emergency egress applications, and building fire/life safety infrastructure. Verify your power supply outputs exactly 28VDC before installation. Compatible with standard STI Stopper II mounting hardware and surface-mounted or recessed configurations on metal or composite door frames.

Installation Notes

Requires 28VDC regulated input with adequate current capacity for alarm horn operation (draw specifications depend on final horn configuration). Mount securely on door frame or surface using provided hardware. Clear spacer should face the exit path for maximum visibility. Fire label must remain visible and unobstructed for code compliance. Ensure wiring terminations are strain-relieved and protected from moisture on exterior-facing installations.
