Manual I/O Test
Press Yes at this prompt to see menus which can help you
test the digital inputs, digital outputs and the CAS200
keypad.
Digital Input Testing
This is a read-only menu that shows the logic state of the 8
digital inputs as H (High- the input is at 5 volts or is not
connected) or L (Low- the input is at zero volts). Inputs 1 to
8 are displayed from left to right. Since inputs are pulled
High when they are not connected, test an input by
shorting it to scanner common and making sure this menu
shows the correct state for that input.
Digital Output Selection
This menu lets you select one of the digital alarm outputs
to test in the next menu.
