Commercial Alarmed Panic Bar Installation and Repair on US-1
Installed and repaired an alarmed exit-device panic bar on a US-1 commercial building — code-compliant egress with a loud local alarm.

A US-1 commercial tenant needed to keep an emergency-exit-only rear door available for egress while stopping employees from using it as a shortcut. The right answer is an alarmed panic bar: full code-compliant single-motion egress, but any use triggers a loud 100 dB local alarm audible throughout the space.
The alarmed exit device we installed is a standard rim panic bar with an integrated alarm module. It runs on a 9V battery and re-arms after a keyed reset. When someone pushes the bar, they leave — the door is fully code-compliant — but the space knows about it. That combination changes staff behavior instantly.
Installation followed standard panic-bar practice: verify the door is the correct hand, transfer the bar's template to the door face, drill and mount the bar chassis, install the strike, and confirm the deadlatch pin engages the strike face against loiding. The alarm module was then armed, tested with a live push, and reset with the supplied cylinder key.
We also repaired a second, older panic bar on the same building whose latch had begun sticking on humid days — a common Florida issue where the latch grease dries and dust gets in. That repair was a strip-and-relube plus a strike re-alignment, not a full replacement. Panic bars are usually repairable; we only replace when internal linkage is bent or replacement parts are no longer available.
The tenant now has one alarmed emergency-egress door on the back of the building and one clean-repaired panic bar on the primary rear exit — both compliant, both quiet under normal use, and both properly serviced for coastal conditions.
Project highlights
- Alarmed exit device with 100 dB local alarm and keyed reset
- Code-compliant single-motion egress preserved
- Second panic bar on the same building repaired and re-lubricated
- Deadlatch engaged for anti-loiding protection
