About the Cel-Fi QUATRA RED ERRC System

Cel-Fi QUATRA RED is a true ERRCS System

Cel-Fi QUATRA RED is the premier public safety amplifier. It is designed to provide consistent coverage in the most challenging structures and to guarantee compliance with the most recent fire codes.

Cel-Fi QUATRA RED is a scalable amplifier consisting of one Network Unit (NU) and up to 6 Coverage Units (CUs). Each CU can provide up to 200,000 sq ft of coverage, equivalent to a 1 watt system, meaning each Cel-Fi QUATRA RED public safety amplifier can provide up to 1,400,000 sq ft of Class A or B and FirstNet radio coverage.

The Cel-Fi QUATRA RED has three key features that differentiate it from other public safety ERRCS:

  • Automatic Isolation - Adapts system to provide exact dB based on jurisdiction requirements
  • Automatic Uplink and Downlink Calculation - Save on equipment costs, manpower, and time.
  • Grid Test - Allows for testing of system without contacting AHJ

The Cel-Fi QUATRA RED Network Unit is to be installed in a fireproof area. The system features optional Battery Backup Unit (BBU), Remote Anunciator, and Emergency Power Off (EPO) Switch to ensure compliance with any jurisdictional regulations. It uses plenum rated coaxial and CAT-5 power-over-ethernet for easy cable runs.

The system reduces the near-far effect common to radio amplification systems and features talk-through capability to alert the end user if they will pass their building inspection.

  • Class A with 56 Channels
  • Class B with 28 Channels (100 kHz & 150 kHz)
  • 700/800 MHz for Public Safety with dedicated FirstNet
  • Automatic Isolation
