What Are Fire Alarm Systems?

Fire alarm systems detect smoke, heat, or flames and then alert building occupants to evacuate. Modern fire alarm systems connect directly to emergency services and integrate with other building or campus safety systems.


A complete fire alarm system has several components that must work together. Smoke detectors sense particles in the air. Heat detectors trigger when temperatures rise rapidly. Manual pull stations let people activate alarms. Control panels manage the entire system and send signals when danger is detected.


Fire alarm systems also include notification devices like horns, strobes, and voice evacuation speakers. These alert everyone in the building, including people with hearing disabilities. In our installations, we ensure every area of your building is properly covered based on California fire codes.

Why Fire Alarm System Integration Matters

Integration connects your fire alarm system to other building systems for better protection. When integrated properly, fire alarms can unlock doors, recall elevators, shut down HVAC systems, and activate video surveillance.


This coordination saves lives during emergencies. We integrate fire alarm systems with access control and door security systems to automatically unlock exits when alarms trigger. Our team connects fire alarms with video surveillance and CCTV systems so security personnel can monitor evacuations in real time.


Many Los Angeles businesses also integrate fire alarms with structured cabling installation (internal link recommendation) to create a unified building management system. This centralized approach makes maintenance easier and improves emergency response.

Our Fire Alarm System Services

Los Angeles Cabling  provides complete fire alarm solutions for commercial, municipal, and residential buildings of all sizes.

Design-Build Services

We design fire alarm systems from the ground up. Our team reviews your building plans, identifies high-risk areas, and creates a system layout that meets California’s fire codes. We handle all permits, inspections, and documentation.

Retrofits & Upgrades

Older buildings often need fire alarm retrofits to meet current codes. We assess your existing system and upgrade components as needed. In our experience working with historic Los Angeles buildings, we find creative solutions that preserve architectural features while ensuring code compliance.

Voice Evacuation Systems

Voice evacuation systems deliver clear instructions during emergencies. In addition to alarms and horns, these systems use pre-recorded or live messages to guide people to safety. We install voice evacuation systems for large commercial buildings where clear communication is critical.

Testing & Inspection

Voice evacuation systems deliver clear instructions during emergencies. In addition to alarms and horns, these systems use pre-recorded or live messages to guide people to safety. We install voice evacuation systems for large commercial buildings where clear communication is critical.

Delayed Egress Integration

Some buildings need delayed egress doors for security without violating fire codes. We integrate these doors with fire alarm systems so they release immediately when alarms activate. This setup works well for data center and server room cabling  projects where security is essential.

How Fire Alarm Installation Works

Our fire alarm installation process follows a proven methodology that ensures quality, reliability and compliance.


First, we conduct a site survey. Our technicians visit your location, measure the space, and identify the best locations for detectors and devices. We note any challenges like high ceilings, HVAC vents, or areas with temperature extremes.


Next, we create detailed installation plans. These plans show every component location and meet California Title 19 requirements. We submit these plans to your local fire marshal for approval before starting work.


After approval, our licensed technicians install all components. We run security cabling behind walls and above ceilings to keep installations clean. Each device gets mounted securely and tested individually.


When installation is complete, we program the control panel and conduct full system testing. Our team simulates alarms in different building zones to verify proper operation. We also train your staff on system operation and maintenance.


Finally, we coordinate final inspections with the fire marshal. We provide all required documentation and certificates of compliance. Our clients receive complete system manuals and maintenance schedules.

Frequently Asked Questions

  • What does a fire alarm system cost?

    Fire alarm system costs depend on building size, features, and local requirements.

Los Angeles Cabling  provides free on-site estimates to give you accurate pricing for your specific needs.

  • How often do fire alarms need inspection?

    California requires annual fire alarm inspections by licensed technicians. Some buildings with critical operations need more frequent testing. We provide scheduled maintenance plans that ensure your system stays compliant and operational year-round.

  • Can you integrate fire alarms with existing security systems?

    Yes, we integrate fire alarm systems with most existing security infrastructure. Our team connects fire alarms to access control systems, video surveillance, and building automation systems. This integration improves both fire safety and overall building security.

  • Do fire alarm systems work during power outages?

    All code-compliant fire alarm systems include battery backup that maintains operation during power outages. We test backup batteries during annual inspections to ensure reliability.

  • What is a voice evacuation system?

    Voice evacuation systems use speakers to deliver clear verbal instructions during emergencies working together with horns and strobes. These systems guide people to safety more effectively than traditional alarm bells. Buildings with complex layouts or high occupancy often require voice evacuation systems.
