SFCD: Federal Commander Digital System - Federal Signal

IO Board
Federal Commander Digital System
The IO Board setup screen allows digital inputs and relay outputs to be associated with hotkeys
for interfacing to third party equipment. Note: The IO Board requires additional steps to be taken
during installation to be functional. It is important that IO Board functionality be tested after
installation to verify correct operation.
Use IO Board
Select this option only when the computer is equipped with an IO Board and the special
installation steps have been performed.
IO Board disabled or not present
Select this option if it is desired to disable the IO Board or the Commander computer is not
equipped with the IO Board option.
Inputs
Each of the eight inputs may be associated with a hotkey or disabled. When associated with a
hotkey an active input will cause the respective hotkey to activate as if the hotkey were clicked.
An active input is defined as voltage detected on the input (5 – 28V) for a period of 500 ms.
Outputs
Similar to inputs relay outputs may be associated with a hotkey or disabled. When associated
with a hotkey the relay will close for the duration specified (in seconds) when the respective
hotkey is clicked. All relays will clear if another hotkey activation occurs that is not programmed
to close the relay even if the duration has not yet expired.
