about us

our history

Our story began in 2021, when owner and founder, Austin Broadrick, formed Sentinel Alarms LLC.

There was an apparent demand for companies that sold affordable yet quality products and provided expert installation and training in the Nashville TN area.

Sentinel Alarms was formed with this goal in mind.
