Public Safety DAS Systems
In an emergency, reliable communication saves lives.
Graystone designs and installs Public Safety ERRCS (Emergency Responder Radio Communication Systems) that keep firefighters, police, and EMS connected throughout your building.
What Are Public Safety DAS Systems?
Public Safety and ERRCS systems boost radio signals inside buildings, ensuring clear two-way communication for first responders.
Concrete, steel, and low-E glass can block radio frequencies, creating “dead zones.”
A properly designed ERRCS eliminates those gaps with antennas and amplifiers that deliver strong, consistent coverage from the basement to the rooftop.
In short: ERRCS keeps first responders connected when it matters most, even in the most challenging environments.
Meeting Fire and Safety Code Requirements
Most cities now require ERRCS installations for new construction, major renovations, and certain occupancy types.

Our systems are engineered to meet NFPA, IFC, and FCC requirements, as well as each local jurisdiction’s amendments.
We work directly with AHJs (Authorities Having Jurisdiction) to make sure your system passes inspection the first time. From plan submittal to acceptance testing, our team handles every detail.
Design
Public Safety & ERRCS Design and Installation Process
Site Assessment
We study your building layout, materials, and current signal strength.
RF DESIGN & ENGINEERING
Our engineers plan antenna placement for the best performance.

INSTALLATION
Installation of Public Safety ERRCS Systems
Before installation, our engineers perform a detailed RF site survey to identify weak coverage areas.
We design a compliant system using high-quality equipment and cabling.
During installation, everything is tested for performance and reliability.
We work night shift, and don't leave footprints behind.
We don't leave footprints behind. You customers may not even notice we were there.
Once complete, we perform grid test, document results & verify compliance, ensuring your building passes final inspection.

Ensure your building meets public safety communication requirements.
Our engineers can test your signal strength, identify coverage gaps, and provide a full compliance plan.
Maintenance and Certification
ERRCS systems require annual testing and recertification to remain compliant.
Our maintenance plans include:
- Annual signal testing and documentation
- Battery and component checks
- Equipment repairs or upgrades if standards change
We keep your system performing and inspection-ready all year long.
Often Installed Together with DAS or Small Cell Solutions
Public Safety ERRCS systems are often installed alongside Distributed Antenna Systems (DAS) or Small Cell networks for full in-building coverage.
If you’re planning a DAS or cellular enhancement project, we can design both systems together to save time, cost, and coordination.
