Indicators

Status Indicator

The red LED, labeled “STATUS”, should be lit whenever the unit is synchronized with the Master GTI (the LED should flicker approximately twice a second). The unit should automatically synchronize, but in the event that it doesn’t, momentarily press the button labeled “RESET”.

Repeater Indicators

Of the two red LEDs for the “REPEATER” interface, one is lit when the “RADIO (is) CONNECTED” and the other is lit when “DTMF (is) DETECTED” from the radio.

Telephone Indicators

Of the three red LEDs for the “TELEPHONE” interface, one is lit when the “MODEM (is) IN USE”, one is lit when “DTMF (is) DETECTED” from the telephone line, and one is lit when the telephone “LINE (is)

CONNECTED”.

Power Indicator

Whenever power is applied, the green LED, labeled “POWER”, should be lit (there is no off/on switch).

Resets

Soft Reset

A soft reset does not alter any user-configurable parameters in a GTI unit’s user database. Pushing the RESET button on the front panel of a standard GTI unit

initiates a soft reset for that GTI unit only. Pushing the RESET button on the Master GTI initiates a simultaneous soft reset for all the GTI units. A simultaneous soft reset of all GTI units can also be made through the GTI Configurator software.

Hard Reset

A hard reset returns each user-configurable parameter in each GTI unit’s user database back to the factory default value, but does not alter any voice prompts that have been recorded. A simultaneous hard reset of all GTI units can only be made through the GTI Configurator software. Power-cycling the GTI units does not perform a hard reset.

Alarms

The Site Controller computer can receive two types of alarm messages from the Master GTI. One, called the LIC alarm (after an earlier interconnect system), indicates a connection problem between the Site Controller computer and the Master GTI, or a problem in the Master GTI itself.

The other type of alarm message, called the RIC alarm (after a second part of the same earlier interconnect system), indicates a connection problem between the Site Controller computer and a specific GTI unit, or a problem in the specific GTI unit itself. A RIC alarm can be received for each specific GTI unit.

IAM

Skip this section if your ELI system is not equipped with an IAM. The locations of the DIP switches, indicators, and reset button on the front panel of the IAM are shown in Figure 44.
