C. 
Radio coverage.
(1) 
Prohibition. Except as otherwise provided in this section, a person may not erect, construct, or modify a building or structure or any part thereof that is subject to this section in accordance with Subsection B above if that building or structure fails to support adequate radio coverage for firefighters, police officers, or emergency medical services personnel.
(2) 
Frequency range. The Chief of Police and Fire Chief or their designee or designees, in consultation with the appropriate police, fire, and emergency medical services personnel, shall determine the frequency range or ranges that must be supported under this section.
(3) 
Adequate radio coverage. For purposes of this section, obtaining "adequate radio coverage" means performing a successful communications test meeting the requirements of Subsections D and E as outlined in Subsection I.
D. 
Required radio field strength inbound to the building or structure.
(1) 
Required minimum average radio field strength. Except as provided in Subsection D(2), for inbound communications, a minimum average radio field strength of one microvolt for analog systems and five microvolts for digital systems is required throughout 85% of the area of each floor of the building when transmitted from the City communications center, or, alternatively, a designee of the Chief of Police or Fire Chief must determine that 85% of the area of each floor of the building or structure meets a minimum signal level of DAQ 3.5 (delivered audio quality) as set forth in the following chart:
Delivered Audio Quality Definitions
DAQ
(Delivered Audio Quality)
Subjective Performance Description
1

(2) 
Exception. If the radio field strength outside the building or structure where the receiving antenna system is located is less than one microvolt for analog systems and five microvolts for digital systems and less than 85% of the area of each floor of the building or structure meets a minimum signal level of DAQ 3.5 (delivered audio quality), the minimum average radio field strength for inbound communications must be equal to or greater than the radio field strength that is delivered to the receiving antenna of the building or structure.
E. 
Required radio strength outbound from building or structure. For outbound communications transmitted to the City communications center, a minimum average radio signal strength of one microvolt for analog systems and five microvolts for digital systems is required, or, alternatively, a designee of the Chief of Police or Fire Chief must determine that 85% of the area of each floor of the building or structure meets a minimum signal level of DAQ 3.5 (delivered audio quality) as set forth in the chart in Subsection D(1) above.
F. 
Amplification; authorization required. If amplification is used in the communications system of a building or structure, all necessary authorizations from the Federal Communications Commission must be obtained prior to the use of the system. Copies of such authorizations must be available to the City communications center on request.
G. 
Enhanced amplification systems.
(1) 
Enhancements. If, in order to achieve adequate radio signal strength under this chapter, a building or structure must enhance its communications systems, the building or structure may use any of the following:

(c) 
A voting receiver system or systems; or
(d) 
Any other system approved by the Chief of Police and Fire Chief or their designee or designees.
(2) 
Battery. If any part of the enhanced amplification system installed to achieve adequate radio signal strength under this chapter contains an electrically powered component, the system must be capable of operating on an independent battery or generator system for a period of at least eight hours without external power input or maintenance. Any independent battery system used pursuant to this subsection must automatically charge in the presence of external power. The building owner, controller, or occupant shall check the status of the battery backup at the same time as required by the Fire Prevention Code for checking the emergency lighting battery backup.

(4) 
Physical location of equipment. The control box for amplification equipment installed pursuant to this section must be clearly marked "Emergency Communications" and physically located in an area that:
(a) 
Is free of hazardous materials, including but not limited to fuel; and
(b) 
Is accessible at all times to City emergency personnel.
(5) 
Provision of information to City communications center. The owner of a building or a structure subject to this chapter shall provide the following to the City communications center:

(b) 
Schematic drawings of the electrical equipment, backup power equipment, antenna system, and any other equipment associated with the amplification equipment.
H. 
Ground system.
(1) 
Single point; internal tie. The communications system, including any amplification systems, cable, and antenna systems, of a building or structure subject to this chapter must be grounded with a single-point ground system of five ohms or less. The ground system must include an internal tie point within three feet of any amplification equipment.
(2) 
Protection. System transient suppression and grounding protection are required for the telephone circuits, alternating-current circuits, and radio frequency cabling in communications systems of buildings and structures subject to this chanter.
I. 
Testing.
(1) 
Testing procedure. Tests of the communications systems pursuant to this chapter must be coordinated with the City communications center. Such testing must be conducted on actual emergency services frequencies authorized by the Federal Communications Commission.
(2) 
Measurement guidelines. Measurements for testing communications equipment pursuant to this chapter must be in accordance with following guidelines:
(a) 
Measurements must be made with a service monitor using a unity gain antenna on a small ground plane;
(b) 
Measurements must be made with the antenna held in a vertical position at three to four feet above the floor;
(c) 
A calibrated service monitor may be used to conduct testing;
(d) 
Where simultaneous measurements for purposes of verifying the accuracy of the measurements are made, a variance of three decibels between instruments is permissible.
(e) 
If varying measurements in one location are obtained, the measurement for that location is the average of those varying measurements;
(f) 
Signal strength must be measured in stairwells and parking areas.
(g) 
The building or structure must be divided into fifty-foot grids, and measurements must be taken as close as possible to the center of each grid.

(4) 
Annual test. A designee of the Chief of Police or Fire Chief shall conduct annual tests of the communications system of the building or structure, at no expense to the building owner.
(5) 
If the communications system of a building or structure fails to demonstrate adequate radio coverage, the owner of the building or structure shall remedy the problem and restore the functioning of the communications system consistent with the requirements of this chapter. In such instances, a designee of the Chief of Police or Fire Chief may retest the communications system at no expense to the building owner,
J.
