CONNECTING THE ALARMS
The Cell Extender provides a dry relay contact for alarming purposes. Both the normally open and the
normally closed states are provided. A separate hermetically-sealed Alarm connector is provided with
wires as specified below:
Wire Color Pin # Function *
Black PIN D Common
White or
Yellow
PIN B Normally Closed
Red PIN A Normally Open
Green PIN C Not Used
* When unit is operational
The dry relay alarm is activated in the following conditions:
Alarm Trigger Conditions
LNA 1 Failure Loss of Gain > 3 dB
LNA 2 Failure Loss of Gain > 3 dB
PA 1 Failure Full Loss of Gain
PA 2 Failure Full Loss of Gain
Power Supply Failure DC voltage < +6VDC
SETTING UP THE BTS MAXIMUM TX POWER
The gain on the CE-1819-10G2 is fixed at the factory. No internal gain adjustments can be made in the
field. The user must verify that the composite input RF power to the Cell Extender does not exceed the
absolute maximum input level (+32.05dBm) in order for the RF output spectral emissions to be
compliant with the FCC spurious emissions limit of -13dBm outside of the assigned frequency block.
The maximum rated composite output RF power for this device is +43dBm.
This equipment complies with Part 24 of the FCC rules. Any changes or modifications not expressly
approved by the manufacturer could void the user’s authority to operate the equipment.
In order to comply with FCC rules for RF exposure, it must be observed that the antenna connected to
this equipment be fixed on an outdoor structure and that it must have a minimum separation distance of
3 meters between it and any person.
In accordance with RSS-131, the manufacturer’s rated output power for this equipment is for single
carrier operation. For situations when multiple carriers are present, the rating would have to be reduced
by 3.5dB, especially where the output signal is re-radiated and can cause interference to adjacent band
users. The power reduction is to be by means of input power or gain reduction and not by an attenuator
at the output of the device.
