Such raceways shall include an easily accessible opening to the roof surface that allows for placement of an exterior antenna and riser access within the building core to each floor within the structure.

Section 510.8 Initial Inspection and Signal Strength Acceptance Test Procedures.

Section 510.8.1

Initial Inspection and Test Procedures. When an engineering study performed for the building contractor or owner has determined that an in-building radio system is required, and upon completion of installation, it will be the building owner’s responsibility to have the radio system tested to ensure that two-way communications coverage on each floor of the building meets the requirements of Sections 510.4 and 510.5. Each floor of the building shall be divided into a grid of approximately 20 equal areas. A maximum of two nonadjacent areas will be allowed to fail the test by not meeting the minimum signal levels established in Section 510.4. Testing of parking garages, stairwells, and non-enclosed areas will be performed as separate tests with statistics gathered separately for signal levels in the primary structure and parking areas. Signal levels shall meet the requirements of Section 510.4 for all areas enclosed by the structure and statistical methods shall not be used to dilute the intent of the coverage requirements established in Section 510.4.

Section 510.8.2

In the event that three of the areas fail the test, in order to be more statistically accurate, the floor may be divided into 40 equal areas. In such an event, a maximum of four non-adjacent areas will be allowed to fail the test. After the 40 area test, if the system continues to fail, the building owner shall have the system altered to meet the coverage requirement established in Section 510.4.

Section 510.8.3

The test shall be conducted using a SERS approved portable radio communicating through the SERS system as specified by the authority having jurisdiction. A spot located approximately in the center of a grid area will be selected for the test, then the radio transmitter will be activated to verify two-way communications to and from the outside of the building through the SERS system. Once the spot has been selected, prospecting for a better spot within the grid area will not be permitted.

Section 510.8.4

The gain values of all systems used to support the signal level requirements of Section 510.4 shall be measured and the test measurement results shall be kept on file with the building owner so that the measurements can be verified each year during the annual tests. In the event that the measurements become lost, the building owner will be required to rerun the acceptance test to re-establish that the facility provides the signal levels established in Section 510.4.

Section 510.9 Annual Equipment Condition Testing.

Section 510.9.1 General.

When an in-building radio system is required, the building owner shall test all active components of the system, including but not limited to amplifiers, power supplies, backup batteries, and related equipment, a minimum of once every 12 months. Amplifiers shall be tested to ensure that the gain is the same as it was upon initial installation and acceptance. These annual tests shall apply to both the bidirectional amplifier method of enhancing signal strength, as well as to any alternative methods that might be employed. The building owner shall notify SERS System Manager in writing two (2) weeks in advance of when annual tests occur, and shall also notify SERS and the Fire District, Fire Marshal by certified mail of the results of the tests. Test records shall be retained on the inspected premises by the building owner.

Section 510.9.2

Backup batteries and power supplies shall be tested under full load for a period of one hour to verify that they will properly operate during an actual power outage. If within the one-hour test period, in the opinion of the testing technician, the battery exhibits symptoms of failure, the test shall be extended for an additional one-hour period until the testing technician confirms the integrity of the battery. Alternative load testing which places a higher short-term demand on the battery system may be required upon verbal request and retested within 10 working days.

Section 510.9.3

All other active components shall be checked to determine that they are operating within the manufacturer’s specifications for the intended purpose.

Section 510.10 Five Year Signal Strength Testing.

Section 510.10.1 General.

In addition to the annual test, the building owner shall perform a radio coverage test a minimum of once every five years to ensure that the radio system continues to meet the signal strength requirements of the original acceptance test. The signal levels established in Section 510.4 and the procedures established in Section 510.8 shall apply to such tests. The results of the five-year test will be provided to SERS System Manager and the Fire District by certified mail. Test reports shall also be retained and be readily available for inspection on the premises by the building owner.

Section 510.10.2

The building owner shall notify SERS System Manager in writing two weeks in advance of the initial, annual, and five year tests.

Section 510.11 Qualifications of Testing Personnel.

Tests shall be conducted, documented, and signed by a person in possession of a current FCC license, or a current technician certification issued by the Associated Public-Safety Communications Officials International (APCO), the Personal Communications Industry Association (PCIA), or a technician employed by SERS.

Section 510.12 Field Testing.

Public safety personnel, after providing reasonable notice to the building owner or his/her representative, shall have the right to enter onto the property to conduct ad-hoc field testing to be certain that the required level of radio coverage is present.

Section 510.13 Additional Frequencies.

The building owner shall modify or expand the emergency responder radio coverage system at his or her expense in the event frequency changes are required by the FCC or additional frequencies are made available by the FCC. Prior approval of a public safety radio coverage system on previous frequencies does not exempt this section.
