What We Do
Regulation 4 Testing
City of Los Angeles Compliance Services
Regulation 4 (Reg 4) testing is required for certain buildings within the City of Los Angeles to ensure that fire alarm and life safety systems remain fully operational and compliant.
Advanced Alarm & Fire provides comprehensive Reg 4 testing services for essential facilities and commercial properties throughout Los Angeles. Our team performs detailed system testing and manages all required documentation to help facility teams maintain compliance with confidence.
What Is Reg 4?
Reg 4 is a City of Los Angeles requirement that mandates periodic testing and certification of fire alarm and related life safety systems in designated buildings. These tests verify that systems function properly and are capable of performing as designed during an emergency.
Reg 4 testing typically includes:
- Functional testing of fire alarm systems
- Emergency voice/alarm communication systems
- Device and notification appliance verification
- System performance confirmation
- Completion of required compliance documentation
What Is an Essential Facility?
An essential facility is a building that must remain operational during and after an emergency event due to its role in public safety, healthcare, education, or critical infrastructure.
Examples of essential facilities may include:
- Hospitals and healthcare facilities
- Emergency response buildings
- Public safety facilities
- Certain government buildings
- Critical infrastructure sites
Because these buildings serve the public during emergencies, their fire and life safety systems are held to heightened reliability and documentation standards.
Advanced Alarm & Fire understands the importance of precision, organization, and minimal disruption when working in essential environments.
