Commercial Fire Alarm & Detection Systems
Avenger Fire & Security designs, installs, inspects, and monitors commercial fire alarm systems throughout Greater Houston. Licensed, NFPA 72 certified, and locally owned since 2010.
Fire Alarm Systems We Offer
We work closely with property owners, general contractors, and building managers to recommend and install the right system for your occupancy type, square footage, and code requirements.
Conventional Alarm Systems
A cost-effective fire detection solution for smaller commercial buildings. The property is divided into general zones, and a single control panel identifies where a fire has been detected. Reliable, straightforward protection at a budget-appropriate price point.
Addressable Alarm Systems
Individually monitors each device throughout the building, pinpointing the exact location of an alarm. Critical for larger facilities — office complexes, warehouses, multi-tenant buildings — where identifying the precise point of activation saves critical response time.
Mass Notification Systems
Designed for large campuses, industrial complexes, and multi-building facilities. These systems use voice messaging, visual notifications, and integrated alerts to safely guide occupants during fires, severe weather, and other emergencies.
Air Sampling Smoke Detection
Continuously analyzes air to identify fire particles before visible smoke or smoldering begins. Ideal for data centers, server rooms, clean rooms, and industrial facilities where early detection is essential to protecting both people and high-value assets.
24/7 UL-Listed Monitoring
All Avenger-installed systems connect to our UL-listed central monitoring station. When your system triggers, our monitoring center immediately dispatches the fire department — day or night, weekday or holiday. No long-term contracts. You own the system.
The Avenger Difference
Since 2010, Avenger Fire & Security has been the locally owned alternative to national chains — licensed technicians, direct AHJ coordination, and a commitment to never locking you into a long-term contract.
Years of Local Experience

72 Certified & Compliant
Every installation is designed and documented to meet NFPA 72, Texas Fire Code, and IFC requirements. We pull the permits, coordinate AHJ inspections, and handle the paperwork.
