L105.3 Acceptance 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 agency's 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 agency's 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.

L105.4 FCC 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.

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