AMDS CONFIDENTIAL 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.

14 To be used only for the purpose for which it is submitted. All rights reserved to AMDS LLC. Reproduction without written 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!!
