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.
