Monrovia, United States – May 18, 2026 / USA Alarm Systems Inc /

Monrovia, CA – USA Alarm Systems, Inc., a family-owned electronic security and fire alarm company headquartered in Monrovia, California, is marking 47 years of continuous service to Southern California residents and businesses. Established in 1979, the company has built a reputation as a full-service security provider, offering electronic security, fire alarm systems, access control, video surveillance, and 24/7 UL-Listed Central Station monitoring supported by redundant dual-coast communications.

As property crime and commercial security threats continue to shift across Los Angeles County and the broader Southern California region, USA Alarm Systems remains focused on delivering the integrity, reliability, and personalized service that have defined the company since its founding. With a 4.9-star customer rating and decades of community involvement, the company serves as a trusted local alternative to national security providers.

“For nearly five decades, our mission hasn’t changed – we protect the people, homes, and businesses that make Southern California what it is. We’ve grown alongside our customers, many of whom have trusted us for generations. That kind of relationship is something a national alarm company simply can’t offer.”

A Legacy of Industry Leadership

USA Alarm Systems was founded by industry veterans who played a significant role in shaping the modern alarm industry in California. Both founders served as past presidents of the California Alarm Association, and one served as past president of what is now the Electronic Security Association (formerly the National Burglar and Fire Alarm Association). The founders were also instrumental in establishing the Greater Los Angeles Security Alarm Association and the Fire/Life Safety Apprenticeship Program, contributing to the professional standards that continue to guide the security industry today.

The company holds a C-10 electrical contractor license from the California Contractors State License Board for fire alarm installations and is licensed by the California Department of Consumer Affairs Bureau of Security and Investigative Services for security system installation. These credentials reflect a sustained commitment to professional excellence and regulatory compliance that benefits every client the company serves.

Comprehensive, Locally Operated Security Solutions

Unlike national security providers that rely on outsourced installation and impersonal monitoring, USA Alarm Systems manages every step of the customer experience in-house. The company’s full-service approach includes residential security systems featuring custom-designed intrusion detection for single-family homes, condominiums, and multi-family properties throughout Southern California. Commercial security and fire alarm systems are tailored for retail, office, industrial, educational, and multi-tenant properties, ensuring each business receives a solution built around its specific operational and compliance requirements.

Access control systems from USA Alarm Systems include keyless entry, credential management, and audit-trail reporting suitable for businesses of varying sizes. Video surveillance solutions provide high-resolution camera systems with remote access and event-based alerts, giving property owners visibility and control from any location. All systems are supported by 24/7 UL-Listed Central Station monitoring backed by redundant dual-coast communications, maintaining uninterrupted protection even during regional outages or natural disasters.

Serving Southern California’s Communities Since 1979

USA Alarm Systems serves homeowners, businesses, schools, and institutional clients across Los Angeles County and Southern California from its Monrovia headquarters at 138 E. Chestnut Avenue. The company is an active member of the Monrovia Chamber of Commerce, reflecting its long-standing presence and consistent service delivery throughout the region.

“Community involvement isn’t just something we say – it’s how we’ve operated since day one. When you call us, you reach a real person in Monrovia, not a call center across the country. That local accountability is what our customers value most.”

As security technology advances through AI-driven analytics, smart home automation, and cloud-based monitoring platforms, USA Alarm Systems continues to incorporate modern capabilities while maintaining the hands-on, relationship-driven approach that has characterized the company for nearly five decades. Service offerings are regularly expanded to address the evolving needs of Southern California homeowners and business operators, guided by the family-owned values present since 1979.
