1.4.3 General Information

The TGB Transceiver is a high performance burst data radio system. The RF

receiver is configured to receive 3 distinct modulation schemes on 3 adjacent

frequencies in the 896 to 940 MHz frequency range.

The TGB RF Transmitter operates on a single configurable channel (12.5kHz,

13.6 KHz, or 25kHz authorized bandwidth depending on the channel and

FCC Rule section governing it’s operation) in the 935 to 960 MHz frequency

range. The transmitter utilizes yet another type of modulation scheme,

different from the three utilized by the receiver.

Transmitted and received data messages are short in nature, meaning that

the radio is intended for burst telemetry type of applications. Larger packets

may, however, be transmitted by sending successive packets.

The TGB operates as a multi-channel transceiver in a “cellular” type system.

The TGB assembles the received messages and forwards them to the TGB

Controller (one per city) via local phone lines. The TGB Controller eliminates

redundant messages (i.e., messages from endpoints that were received by

more than one TGB) before forwarding them to the NOC via a high-speed

connection (ISDN, T1, etc).

The TGB shall also notify the NOC of any alarm indications, such as

tamper/intrusion, temperature alarms, or power failure.

The TGB is installed inside an equipment enclosure containing a 24 VDC

power supply and battery charger (FCC Part 15 Class B Compliant), a cavity

duplexer/combiner allowing for single antenna operation, and all necessary

grounding and lightning protection hardware needed to protect the TGB under

normal operation.

3.4. Low Voltage Alarm and Disconnect

Upon Commercial AC Power Failure, the TGB will immediately notify the

network via the AC POWER Alarm; at which time the system will begin

operating on battery backup. After duration determined by capacity of

batteries, charge state, temperature, and current draw, the output voltage of

the batteries will decrease.

consent is prohibited.

AMDS CONFIDENTIAL

The system provides for local visual (BATTERY FAILURE) and remote

indication the system output voltage has fallen below a preset level. This

level is set at the factory at 24V. The alarm clears automatically when the

system output voltage increases above this level.

The Low Voltage Alarm is the final indication that the TGB system is about to

shut down. Once asserted the TGB will shutdown in approximately 8 hours

unless commercial AC power is restored..

4. Maintenance

4.1. General

The TGB is designed to require minimal maintenance. Care should be taken

to observe the appropriate precautions when working inside the TGB

enclosure.

!!! The circuit cards used in this equipment contain static sensitive

devices. Observe precautions for handling ESD sensitive items. A, ESD

wrist strap is located inside the front door of the TGB enclosure.

4.2. Preventative or Routine Maintenance

4.2.1. Surge arrestor

The antenna surge arrestor is of the gas discharge tube type. A gas tube

element may not always show outward signs of failure or degradation,

therefore routine maintenance and inspection is recommended. The gas

tube element can be replaced by simply removing the nut and replacing

the element. If the number of thunderstorms in an area is high, gas tubes

should be inspected more frequently. Gas tube degradation is dependant

on the number of strikes as well as the intensity of the strikes. As obvious

as it may seem, gas tube elements should never be inspected, or

replaced, when a thunderstorm is approaching or occurring.

4.2.2. Airflow

Without adequate airflow, TGB performance may degrade due to

increased temperature. At least once per year, the TGB enclosures

should be checked for proper airflow. This includes verifying operation of

all fans and ensuring that any air filters are free of dust and dirt.

4.3. Circuit Card Installation/Replacement

No operator or user serviceable equipment is provided in the TGB with the

exception of battery replacement and other housekeeping items.

IF ANY HARDWARE OR SOFTWARE FAILURE IS REPORTED OR

DETECTED SERVICING IS TO BE PERFORMED BY QUALIFIED AMDS

TECHNICAL SERVICE PERSONNEL ONLY!!

consent is prohibited.

AMDS CONFIDENTIAL

4.4. Battery Replacement

!!! Warning !!!

The batteries are a source of energy and can be hazardous if shorted.

Exercise caution.

The batteries are rated for a 5-yr life at 25˚C and 27.5VDC float voltage.

Extended periods of operation above 25˚C will reduce battery life (rule of

thumb: 50% life reduction per every 10˚C increase. After this time it is

appropriate to have a change-out program. In the event of frequent deep

discharges it is possible that the batteries may require earlier replacement.

Prior to disconnecting batteries, disconnect the battery cable from the right

hand side of the rectifier cabinet. Remove jumpers from the battery terminals

and remove old batteries. Install new batteries and reconnect jumpers.

Before reconnecting battery cable to right hand side of rectifier cabinet,

measure open circuit voltage between pins 1 & 2. The voltage should be

above 22VDC. If the voltage is below 22VDC, do not proceed with

connection—batteries must first be charged before installation.

4.5. Battery Recharging

!!! Warning !!!

The batteries are a source of energy and can be hazardous if shorted.

Exercise caution.

The shelf life of the batteries is 6 months from the date of charge. If the

battery has been stored for more than 6 months, it should be recharged prior

to installation.
