General 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.

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.
12 To be used only for the purpose for which it is submitted. All rights reserved to AMDS LLC. Reproduction without written consent is prohibited. 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 !!! 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. Before replacing any circuit cards in the TGB Electronics Assembly (Chassis), first halt the Fusion Processor, then after it has successfully shutdown, switch the circuit breaker/ disconnect to the OFF position. Once the circuit cards
13 To be used only for the purpose for which it is submitted. All rights reserved to AMDS LLC. Reproduction without written consent is prohibited. are replaced, switch the circuit breaker/disconnect to the ON position to restart. 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.
