Base Station Receiving or Control Network Antennas
Provide the required antenna system for each network including grounded
lightning-protected, omnidirectional, coaxial antenna, together with all
necessary mounting brackets and supports for installation; line static
arrester, and interconnecting cable in the necessary length for each
receiver. Provide antennas for the dual networks with maximum separation
at the emergency communication center. Antenna supporting structures shall
comply with EIA/TIA-222. Provide antennas tuned to the operating
frequency and designed to withstand destruction by natural elements under
normal operating conditions. The complete antenna assemblies shall be
corrosion resistant and designed for reliable operation under adverse
climatic conditions including [161] [242] km/h[100] [150] mph winds, rain,
ice, and snow storms. Antenna cable(s) shall be minimum 95 percent shielded
type. Run antenna cables in galvanized rigid steel conduit.
2.6.15
Provide lightning arresters for base station antennas in accordance with
NFPA 70. Base stations shall not exhibit mis-operation or failure when
electrical transients of IEEE C62.41 Category B are applied to the AC power
line. [Provide Metal Oxide Varistor (MOV) protection on all primary power
circuits in accordance with ANSI C62.11.]
2.6.16
Field Programming Capability
Furnish field programming capability, including: Interconnecting cables,
software, firmware, hardware, and manufacturer's licenses and passwords
necessary to permit revisions to data stored in memory as follows: Addition
or deletion of transmitters, changes in zone numbers and identification,
changes in alarm level and displayed message (alarm vs. supervisory),
alphanumeric label changes, and password changes, to be made by the
Government after contract completion.

COMPUTER-AIDED DISPATCH (CAD) SYSTEM
**************************************************************************
NOTE: Except for larger consolidated communication
centers, select the single CAD system option. If a
new CAD system is not desired, delete these
paragraphs. Consult the Federal Fire Chief to
determine the requirement for a CAD system and the
historical and anticipated daily (average and peak)
call loading.
**************************************************************************
In the communication center emergency operations room, provide [one] [two]
Class 3 CAD system[s] in compliance with NFPA 1221. Provide hardware,
firmware, and software required for a complete and useable system. Provide
IBM-compatible computer[s] with minimum 4 gigabyte hard drive, 100
megabyte or larger removable drive, 3.5" floppy disc drive, CD ROM drive,
56 Kbps modem, monitor, keyboard, and printer. Provide standard,
commercially-available software loaded on the computer hard drive, and
backed up on CD ROM. System shall be capable of accommodating an average
load of [ ___ ] calls per 24 hour day and a peak load of [ ___ ] calls per
hour.
