Supp. No. 9
(f)
All BDA equipment, cable and antenna systems should be grounded with a single
point ground system of five (5) ohms or less. The ground system must include an
internal tie point within three (3) feet of the amplification equipment. System
transient suppression for the telephone circuits, ac power, radio frequency (RF)
cabling and grounding protection are required as needed.
(g)
A minimum average in-building field strength of 3.9uV (-95 dBm) throughout
95% of the area of each floor of the building for inbound and outbound signals
transmitted from or to the appropriate emergency service radio systems providing
coverage for public safety services (law enforcement, fire, and medical) to the
building. (95% coverage or reliability means the radio will receive and transmit
100% of the time within 95% of the building's area) If the field strength
OUTSIDE the building, where the receive antenna system for the in-building
system is located, is less than the -95 dBm, then the minimum required in-
building field. Strength shall equal the field strength being delivered to the receive
antenna of the building.
(h)
The Noise floor must be determined and the in-bound signal must be 15 dBm
above the noise floor determined level, meeting the requirements of current
version of TSB-88A standards.
(i)
The BDA System must be rebanding capable and/or compliant.
(j)
This BDA System should also accommodate the 24 MHz of public safety
spectrum, being redesigned for broadband use to allow for nationwide
interoperable broadband communications by public safety users. The frequencies
used shall be those that are currently in use by the Morrisville Fire/Rescue
Department. The install should include all appropriate bi-directional
Amplifier/repeaters, cable hangers, coax cable extensions (measured to distance
and cut to size), RF splitters, proper antenna placement, proper antenna type, RF
connectors, lightning protection, and grounding equipment. Installation should be
as clean and professional as possible to minimize visual impact at each location.
The vendor is required to furnish (2) complete bound system manuals upon
completion of the system installation along with one electronic copy. This manual
should include the following; a complete instructions manual for all equipment in
the system be provided, Instructions for the determination of trouble reporting,
including all trouble report telephone numbers and personnel contact information
be provided with the system. A complete schematics and parts list for all
equipment in the system.

(a)
Where buildings and structures are required to provide amenities to achieve
adequate signal strength, they shall be equipped with any of the following to
achieve the required adequate radio coverage; radiating cable system(s), internal
