Emergency Responder Radio Coverage Systems (ERRCS)

Why ERRC?

First Responders must be able to maintain 2-way radio communications throughout a building in an emergency situation. Whether they are responding to a fire, medical emergency, or domestic threat, they cannot be in a situation where their radios fail to communicate, this is literally a matter of life and death.

Emergency Responder Radio Coverage Systems (ERRCS) are utilized in large buildings and underground structures to provide this critical need to communicate. Emergency Responder Radio Coverage Systems are an important lifesaving technology that enables emergency responders to have effective and reliable communications.

What is ERRC?

The emergency responder radio systems include a combination of a repeater also known as a Bi-Directional Amplifier (BDA), a Distributed Antenna System (DAS), and an electrical power backup system, which in most cases is a Battery Backup System (BBU).

The antenna system is comprised of a Donor Antenna that is attached on the outside of the building or structure and a Distributed Antenna System (DAS) which is an array of multiple antennas that provides the signal transmission coverage for the building’s interior compartments and levels.
Through the Antenna System, the BDA transmits and receives boosted radio transmissions between a base station and the interior of large structures that would otherwise not be able to communicate with the outside environment.

The BDA is supported by an emergency Power Backup System or Battery Backup (BBU) system which includes a power supply, energy storage, and battery charging systems.

The combination of these systems is known by many names such as:
• Emergency Responder Radio Coverage Systems (ERRCS)
• Emergency Responder Communications Enhancement Systems (ERCES)
• Public Safety Distributed Antenna System (PSDAS)
• Two-Way Radio Communications Enhancement Systems
• Public Safety DAS Systems
• Public Safety Radio Enhancement Systems

Why Choose U.S. Mobile Communications?

You need to hire experienced professionals that are able to mitigate the challenges faced in the installation and provisioning of these ERRC systems. The challenges include the environment in and around the buildings i.e. the type of construction and materials used and the nearby terrain and structures, all that can impede the signals path.

With the knowledge of our experienced professionals and through the hundreds of Emergency Responder Radio Coverage Systems that we have designed and installed, we have the expertise to provide the best and most reliable ERRC systems available. All of our Emergency Responder Radio Coverage Systems are fully compliant with all applicable International Fire Code (IFC) and the National Fire Protection Association (NFPA) codes for public safety DAS systems.

Along with ensuring IFC and NFPA codes are met, our specialists will also provide other services, including:

• Tests for RF coverage.
• Plans for system maintenance.
• Local fire code requirements and ordinances consultation.
• Complete installation of the ERRC systems and total integration.
