HOME FIRE ALARM SYSTEMS
Fire and Smoke pose a serious threat to every type of structure—and to the people inside.
At Commercial Fire & Security, Inc. we go to great lengths to make sure your property and assets are safe, 24 hours a day. We offer an extensive array of fire detection systems, smoke and heat detectors, manual pull stations, sprinkler monitoring, gas leak detection and voice evacuation systems, just to name a few.
Behind it all is our TMA-Five-Diamond, nationally recognized, UL-listed 24-hour monitoring center. In an emergency, our highly trained personnel will notify you and the authorities in seconds.
No matter how extensive your fire detection system needs, we're happy to help. We provide full-service system design, installation, system maintenance, testing and inspections services.
