Commercial Fire Alarm Systems for Houston Businesses
Fire Alarm Services From Design to Final Inspection
Design, installation, inspection and monitoring from one licensed local team. We get your project through final inspection and keep your building compliant after.
Design and permitting. We design systems to NFPA 72 and local code, prepare the submittal, and work with the fire marshal through approval.
Installation. Rough-in through trim-out for new construction, tenant improvements and renovations, scheduled around your project.
Inspection, testing and maintenance. Required inspections with documented reports you can hand to the fire marshal or your insurer.
24/7 monitoring. Alarm signals go to our Texas-based monitoring center, which dispatches the right responders. Already have a system? We can take over monitoring from your current provider.
Service and repair. Troubleshooting, device replacement and panel upgrades on existing systems, including Fire-Lite, Silent Knight, Potter and most major brands.
