L104.2.2Technical criteria. The fire code official shall maintain a document providing the specific technical information and requirements for the emergency responder radio coverage system. This document shall contain the various frequencies required, the location of radio sites, effective radiated power of radio sites, and other supporting technical information.

L104.2.3Secondary power. Emergency responder radio coverage systems shall be provided with an approved secondary source of power. The secondary power supply shall be capable of operating the emergency responder radio coverage system for a period of at least 24 hours. When primary power is lost, the power supply to the emergency responder radio coverage system shall automatically transfer to the secondary power supply.

L104.2.4In-building coverage system requirements. If used, in-building coverage systems shall meet the following requirements:

1. All in-building coverage system components shall be contained in a National Electrical Manufacturers Association (NEMA) 4-type waterproof cabinet.

2. Battery systems used for the emergency power source shall be contained in a NEMA 4-type waterproof cabinet.

3. The in-building coverage system and battery system shall be electrically supervised and monitored by a supervisory service, or when approved by the fire code official, shall sound an audible signal at a constantly attended location.

4. Equipment shall have FCC certification prior to installation.

L104.2.5Additional frequencies and change of frequencies. The emergency responder radio coverage system shall be capable of modification or expansion in the event frequency changes are required by the FCC or additional frequencies are made available by the FCC, or public safety entities operating in a given jurisdiction make modifications, changes, or upgrades to their communication system(s) that change the frequencies such systems utilize.

L104.2.6Availability. The in-building coverage system, in general, shall operate according to its intended specification with "5-9s" availability of 99.999 percent of each year; i.e., no critical component of the system shall be out of normal operation for more than 5.26 minutes of each year.

L105Installation requirements. The installation of the public safety radio coverage system shall be in accordance with Sections L105.1 through L105.5.

L105.1Approval prior to installation. Amplification systems capable of operating on frequencies licensed to any public safety agency by the FCC shall not be installed without prior coordination and approval of the fire code official.

L105.2Minimum qualifications of personnel. The minimum qualifications of the system designer and lead installation personnel shall include at least one of the following:

1. Certification of in-building system training issued by a nationally recognized organization or school.

2. A certificate issued by the manufacturer of the equipment being installed.

These qualifications shall not be required where demonstration of adequate skills and experience satisfactory to the fire code official is provided.

L105.3Acceptance test procedure. When an emergency responder radio coverage system is required, and upon completion of installation, the building owner shall have the radio system tested to ensure that two-way coverage on each floor of the building is a minimum of 95 percent. The test procedure shall be conducted as follows:

1. Each floor of the building shall be divided into a grid of 20 approximately equal test areas.

2. The test shall be conducted using a calibrated handheld or hip-worn device of the latest brand and model used by the agency talking through the agencys radio communications system.

3. Failure of a maximum of two nonadjacent test areas shall not result in failure of the test.

4. In the event that three of the test areas fail the test, in order to be more statistically accurate, the floor shall be permitted to be divided into 40 equal test areas. Failure of a maximum of four nonadjacent test areas shall not result in failure of the test. If the system fails the 40-area test, the system shall be altered to meet the 95 percent coverage requirement.

5. A test location approximately in the center of each test area shall be selected for the test, with the radio enabled to verify two-way communications to and from the outside of the building through the public agencys radio communications system. Once the test location has been selected, that location shall represent the entire test area. Failure in the selected test location shall be considered failure of that test area. Additional test locations shall not be permitted.

6. The gain values of all amplifiers, if applicable, shall be measured and the test measurement results shall be kept on file with the building owner so that the measurements can be verified during annual tests. In the event that the measurement results become lost, the building owner shall be required to rerun the acceptance test to reestablish the gain values.

7. As part of the installation, a spectrum analyzer or other suitable test equipment shall be utilized to ensure spurious oscillations are not being generated by the subject in-building coverage system. This test shall be conducted at time of installation and subsequent annual inspections.

8. A test shall be considered a "failure" when a transmission from the test device within the building fails to deliver intelligible audio or data to the appropriate public safety dispatch center or equivalent as would be expected during normal operation; and/or when a transmission from a public safety dispatch center or equivalent fails to deliver intelligible audio or data to the test device within the building as would be expected during normal operation.

L105.4FCC compliance. The emergency responder radio coverage system installation and components shall also comply with all applicable federal regulations including FCC 47 CFR Part 90.219.

L106Maintenance. The emergency responder radio coverage system shall be maintained operational at all times in accordance with Sections L106.1 through L106.4.

L106.1Testing and proof of compliance. The emergency responder radio coverage system shall be inspected and tested annually or whenever structural changes occur including additions or remodels that could materially change the original field performance tests. Testing shall consist of the following:

1. In-building coverage test as described in Section L105.3.

2. Signal boosters in-building coverage systems shall be tested to ensure that the gain is the same as it was upon initial installation and acceptance.

3. Backup batteries and power supplies shall be tested under load of a period of one hour to verify that they will properly operate during an actual power outage. If, within the one-hour test period, the battery exhibits symptoms of failure, the test shall be extended for additional one hour periods until the integrity of the battery can be determined.

4. All other active components shall be checked to verify operation within the manufacturers specifications.

5. At the conclusion of the testing, a report, which shall verify compliance with Section L105.3, shall be submitted to the fire code official.

L106.2Additional frequencies. The building owner shall modify or expand the emergency responder radio coverage system at their expense in the event frequency changes are required by the FCC or additional frequencies are made available by the FCC, or public safety entities operating in a given jurisdiction make modifications, changes, or upgrades to their communication system(s) that change the frequencies such systems utilize. Prior approval of a public safety radio coverage system on previous frequencies does not exempt this section.

L106.3Field testing. Agency personnel shall have the right to enter onto the property at any reasonable time to conduct field testing to verify the required level of radio coverage.

L106.4Planned outages. Any planned outages of the in-building coverage system, such as for replacement or upgrade of the system, shall be done with the written approval of an entity legitimately representing public safety agencies operating within the jurisdiction, such as a county sheriff.
