supplies are recommended for higher reliability. The dual
AC power supply system also contains two charge controllers
and two sets of standby battery to provide power during
AC power failures. Each battery is float charged while the
power supply is on and has 100 amp-hours as standard
capacity. Additional batteries can be purchased if the system
requirement needs.
•
In locations where commercial power is not available and
solar panel charging is impractical, primary cell batteries
capable of powering an RF-2000E/EW repeater in excess of
a year are available. In such applications, the battery instal-
lation should be given an environmental shelter according to
the manufacturer’s recommendations.
3. ALARMS
•
The RF-2000E/EW repeater can be provided with an
optional alarm system to remotely monitor the repeater site.
Conditions that are typically monitored are listed below:
Standard Telemetry:
a) A and B Battery Voltage
b) Battery Temperature
Standard Trip Points:
c) A and B Battery Major Alarm (2)
d) East and West RF Output Low (2)
e) Amplifier Alarm
f) Cabinet Door Open
g) 6 Each User Points, Strappable:
Closed or Open = Alarm

FCC ID: EK2A101
5. ORDERING
•
The RF-2000E/EW RF Repeater As-sembly is ordered by
specifying the system model number RF-2000E/EW-XX
(Tables 5.1, and 5.2). Spare amplifiers and in-service
amplifier change kit (Ref. Sec. 8.07) are listed in Table 5.3.
Attenuators are provided by specifying their part numbers.
Transmission engineering must be completed before ordering
because the necessary attenuator values are determined from
the path calculations. Part numbers are listed in Table 5.4.
•
When doing the initial system layout of a radio hop which
includes a RF-2000E/EW RF Repeater Assembly, several fac-
tors must be considered prior to ordering, to ensure correct
antenna connections.
(a) Terminal transmit-Repeater receive frequencies (F1
and F2 or F1, F3 and F2, F4).
(b) Physical mounting of RF-2000E/EW repeater on tower
(or crossarms) in relation to mounting of antennas.
The RF-2000E/EW repeater may be factory-tuned so that f1
RCV (LEFT) associates with the lower of the two frequencies
and f2 RCV (RIGHT) with the higher; or vice versa. By com-
paring the factors listed above, correct antenna/coaxial
feeding connections will result. The equipment order must
specify the f1 and f2 frequencies. For example:
f1 RCV=2204MHz and f2 RCV=2245MHz
or
f1 RCV=2245MHz and f2 RCV=2204MHz
