We are proud to offer the CEL-FI By Nextivity product line this wonderful product lines to include the  Emergency Responder Radio Communications System (ERRCS)

We have been working with CEL-FI over the past year and Have deployed their products for Cellular and Publics safety  coverage solution and are working with local AHJ to deploy the QUATRA RED in our markets. 

We also provided a pre installation site survey that will clarify if  the need of an ERRCS would be required  for the facility 

to meet the local AHJ compliance for occupancy approval. This will include a Grid type of coverage ERRCS AHJ compliance report and a design if the site does not meet the ERRCS coverage compliance. 

Please review the provided martials to include the video and call or email us with any questions. 

Introduction to Public Safety System

  1.     Communications for First Responders has become mission critical over the last few years. It’s always been                     important, but now  it’s an integral part of the incident response game plan.
  2.     In building public safety coverage is becoming mandatory . Some regions are                 
             already there. Many more are getting there.
    3.    Public safety is incorporating cellular technology into the tool box. (FirstNet,
            and many others globally.)


  • The concept of ERRCS was first introduced in the 2009 International Fire Code Section 510
  • In 2012, ERRCS was included in NFPA 1 section 11.10
  • Apply to new construction or major renovation in buildings over 3 4 floors
  • Apply to commercial buildings only

QUATRA RED Emergency Power-off Switch

Cel-Fi’s QUATRA RED Emergency Power Off Switch (EPO) can instantaneously shut down the ERRCS solution from a single point to eliminate the risk of combustion caused by electricity or static. Designed to prevent inadvertent operation and can be installed in any location designated by the authority having jurisdiction.

QUATRA RED Network Unit

The Network Unit (NU) processes FirstNet and LMR off-air signals digitally to provide reliable and interference-free coverage. PoE based architecture and Cel-Fi patented algorithms for automatic setting of uplink and downlink gain, reduces time and cost of installation significantly, making Cel-Fi QUATRA RED the most compelling public safety solution in the market.

QUATRA RED Coverage Unit

The Coverage Unit (CU) amplifies FirstNet and LMR signals up to 24 dBm and 30 dBm output power. The ease of installation plus the SelfOrganizing Edge Intelligence makes Cel-Fi’s QUATRA RED the most compelling solution in the market.
