the external power supply used to power the
LTC 8540/00 Alarm Interface unit is not
connected to a wall outlet.
2. Using the cable supplied with the LTC 8540/00
Alarm Interface Unit, connect one end of the
cable to "PORT 1" on the rear of LTC 8713
Series Alarm Port Expander. Connect the other
end of the cable to the "RS-232" port on the

Series Alarm Port Expander, connect one end
of the cable to the connector marked
"SYSTEM" on the LTC 8713 Series. Connect
the other end of the cable to the connector
marked "ALARM" on the Allegiant series
system.
In this configuration, 256 alarms can be
configured using one LTC 8713 series unit and
four LTC 8540/00 units. A LTC 8713,
configured as an alarm port expander hub, may
be used to extend the number of alarms to
1024. The LTC 8713 Series units can be
configured as an alarm port expander hub via
DIP switches S402-5 and S402-6. See Typical
LTC 8713 Series Alarm Port Expander
Application For More Than 256 Alarms under
ILLUSTRATIONS. Note that when using the
LTC 8713 as an alarm port expander hub, the
baud rate must be set to 57600 via DIP switches
S401-1 through S401-3. Refer to the applicable
Allegiant system installation instructions to
configure its alarm port to the 57600 baud rate.

OPERATION

1. Connect the external power to the LTC 8540/00
Alarm Interface Units. The power LED on the
LTC 8540/00 Alarm Interface Units should be
on.
2. Turn on the Allegiant Series main bay and the
LTC 8713 Series Alarm Port Expander. The
power LED on the LTC 8713 Series unit should
be on.
3. Note that the system Tx LEDs on the front
panel of the LTC 8713 Series indicate whenever
alarm data is being sent to the Allegiant series
unit from the LTC 8713 Series. The system
Rx LEDs indicate when alarm data is being
received from the Allegiant series unit. This
data consists of "alarm verification" and "relay
action" data. Both types of data are sent to the
LTC 8713 unit immediately after the Allegiant
series unit receives alarm data. This data will
also be sent back and forth on an occasional
basis to maintain current system status.
4. The "alarm" port Rx LEDs will indicate when
alarm data is being received from the
corresponding LTC 8540 Series Alarm Interface
Unit. The "alarm" port Tx LEDs indicate that
"alarm verification" data and "relay action" data
is being sent to the respective LTC 8540/00
unit. This data will also be sent back and forth
on an occasional basis to maintain current
system status.
