It’s critical for residents and staff to stay safe in a building during an emergency, as well as for law enforcement, firefighters, and other emergency responders who might need to enter. In this case, Emergency Responder Radio Communication Systems, or ERRCS, are helpful. A weak radio or cellular signal inside your building could be a violation of local safety codes. But don’t worry, we’ll explain everything in this post so you know what ERRCS is, why it’s important, and how to stay in compliance with the code.
What is ERRCS?
ERRCS stands for Emergency Responder Radio Communication System. In order to ensure that first responders, such as police, firemen, and emergency medical services, can communicate via radios, a specialized system has been installed inside buildings. Radio signals are blocked by a lot of big buildings, particularly those composed of steel, concrete, or underground levels. By intensifying and dispersing those signals indoors, ERRCS aids in the solution. Many jurisdictions have laws requiring this system, particularly those governed by codes such as the International Fire Code, NFPA 72, and the Florida Fire Prevention Code. To find out what’s required in your area, check the requirements of your local fire code.
Why Is ERRCS Important?
Imagine a firefighter in a burning building, unable to contact their team because there’s no radio signal. That’s a life-threatening risk. ERRCS is important because:
- It keeps communication strong during emergencies.
- It helps save lives, both the people inside and the responders.
- It makes sure your building passes fire code inspections.
It may be legally required before you get a certificate of occupancy.

When Is ERRCS Necessary?
While many buildings do require an ERRCS, not all do. It may be necessary if your building is composed of steel, concrete, or Low-E glass and:
- Is larger than a specific number of square feet (typically over 50,000 sq ft)
- Features subterranean spaces like parking garages or basements
- Does not pass a test of radio signal strength conducted by your local fire department or a certified technician.
Regular testing is crucial because even if your building has passed previously, coverage may be impacted by new tenants, renovations, or changes to nearby buildings.
ERRCS Requirements: Key Points to Know
ERRCS Requirements: Important Things to Understand
Here are the guidelines that most building owners must adhere to in order to remain in compliance:
- Signal Power
All floors of your building, including basements and stairwells, must have minimum signal levels (typically -95 dBm or higher). - Area of Coverage
While general areas need 95% coverage, critical areas like fire command rooms, mechanical rooms, and stairwells need 99% coverage. - Monitoring of the System
Two crucial elements of ERRCS systems are battery backup and 24-hour fault or failure monitoring. - Examination and Upkeep
Most codes require an annual inspection and recertifying by a certified professional. - Adherence to the FCC
All FCC regulations must be followed by your system, and it must not interfere with public safety frequencies.
How to Get Started
If you’re not sure whether your building needs an ERRCS or complies with the regulations, follow these steps:
- Set up a signal test.
Employ a certified ERRCS technician to determine the strength of the current signal in your building. - Consult the Local Government
Speak with your local fire marshal or code official to find out what is required. - Get a Specialized ERRCS Solution
If required, work with a reputable supplier to install a system that complements your building’s size, composition, and design. DAS System Installation and BDA System Installation often go hand-in-hand with ERRCS, depending on the building layout. - Keep Up Your Upkeep
Installing ERRCS is not enough; in order to keep it code compliant, you must test and maintain it annually.
Final Conclusion
An ERRCS isn’t just a tech upgrade, it’s a lifesaving safety system. For property owners, facility managers, and developers, installing and maintaining an ERRCS is often not optional, it’s part of building code. Make sure you stay up to date, get your building tested, and work with experts who understand the rules.
