ERRCS/Public Safety

Emergency Responder Radio Coverage Systems

In-building radio communication enhancement systems also known as Emergency Responder Radio Coverage Systems (ERRCS) and Public Safety Distributed Antenna Systems (DAS) are installed so that emergency service personnel such as fire, paramedics, police, and other governmental agencies can communicate inside buildings and structures where service would otherwise be impossible. These systems are particularly necessary in places where RF penetration is difficult such as underground parking structures, basements and stairwells.

Cosco Fire Protection has an experienced team with the relevant FCC and manufacturer certifications as well as extensive experience in fire/life safety and in-building distributed radio coverage enhancement systems to evaluate, design, plan, install, and maintain your ERRCS system.

  • Radio repeater systems designed to give first responders reliable radio coverage in your building.
  • Systems are designed to comply with NFPA 1221, International Fire Code Section 510, and any other applicable AHJ codes.
  • We install ERRCS systems of any size.


Cosco DAS can deploy your private network. Nearly any industry can benefit from a private CBRS, DAS, or WiFi network whether it be for increased security, connectivity, or data capacity and coverage.

Maintenance & Monitoring

NOC (Network Operations Center) monitoring is available 24 hours a day to ensure network performance of Cellular, Enterprise, and Public Safety network systems. Our services monitor repeaters, network equipment, generators, climate control, power plants, battery backups, and more. When there is a problem, our team of engineers can be deployed to troubleshoot and solve the issue, often before users have become aware of it.
