Logic Output Terminals
The logic outputs are open collector type designed to drive externally-mounted relays or other indicating
circuits. Each output can sink up to 100 mA of current when active. External circuitry (relays, indicators,
etc.) must be powered from an external power supply of the same voltage used to power the ARC module
(12 to 24 V dc). The ground (or dc common) terminals of the external power supply must be tied to either
of the GND terminals of the ARC. The following table outlines each output’s active state:
Output Function Notes
1 AMI Fault This output will become active when the ARC receives an error message
from the AMI; or when the ARC no longer detects audio on the AMI
output during the playing of an alarm message or page.
2 Ethernet Fault This output becomes active when the Ethernet/Network connection is
broken between the ARC modules and they can no longer communicate
with each other.
3 Priority Under normal operation, this output is active only on the ARC module
that is controlling the alarm play.
If the Ethernet connection is broken between ARCs, this output will be
active on both units.
4 Data Fault This output is active when the ARC loses data communication with the
AMI. This can indicate a problem with the RS-232 or RS-485 cable
connection.
5 Spare Reserved for future use.
6 Spare Reserved for future use.
7 Spare Reserved for future use.
8 Data Fault
During Message
This output is active when the ARC loses data communication with the
AMI while the AMI is playing a message.
In this case, the output should be used as a “reset” input to the AMI. This
resolves the issue where RS-232 or RS-485 communication is lost, and the
ARC has no means to command the AMI to stop playing a message or
page.
