DAS System Installation in Orange County / Orlando – Summary

Byorlandodassolutions

In Orange County and the City of Orlando, Distributed Antenna Systems (DAS) must comply with public safety communication requirements as outlined in IFC Section 510. These regulations ensure reliable in-building radio coverage for first responders during emergencies.

Key Compliance Requirements:

  • Code Reference: International Fire Code (IFC) 510
  • System Standards: NFPA 1225 (2022 Edition) is used as the reference standard for the design, installation, and testing of Emergency Responder Communication Enhancement Systems (ERCES).
  • Performance Threshold: DAQ (Delivered Audio Quality) of 3.0 or higher must be achieved for both uplink and downlink.
  • Coverage Area: 95% general building coverage and 99% in critical areas such as fire command rooms, exit stairwells, and emergency generator rooms.

Installation and Testing Process:

  1. Conduct a site survey to determine signal strength and system needs.
  2. Design the DAS system following NFPA 1225 standards.
  3. Install the system components, including donor antennas, coaxial cabling, fiber optics, and indoor antennas.
  4. Perform field testing using proper testing equipment (spectrum analyzers, signal generators, etc.).
  5. Submit the final report, including DAQ maps and test results, to the AHJ (Authority Having Jurisdiction) for approval.

Important Notes:

  • All equipment must be FCC-certified and UL-listed where applicable.
  • Backup power (24 hours minimum) is required.
  • Annual testing and maintenance are mandatory.

By following these steps and code requirements, DAS integrators can ensure full compliance and help save lives by enabling seamless emergency radio communication inside buildings.
