4.0 I/O Control
The I/O control feature allows an operator to have input events drive output responses. For example, an
input connected to a vibration sensor or glass-break detector on a window can be linked to an alarm
output so that a broken window will sound an alarm.
I/O control is managed through the I/O Config and Link Config tabs in the Setup System window. I/O
Configuration defines the input and output points, and Link Configuration ties the inputs to the outputs.
Certain I/O points are dedicated to specific input/output functions (i.e. the RTE input, the door switch
input, the door lock output, the door alarm output). These points are not available for I/O control
assignment (refer to “Configure Dedicated I/O Points” on page 17 in section 3).
Manual control for output points is also available, allowing an operator to manually turn-on/enable or
turn-off/disable an output point. This allows an operator to control an output point and to override a link
event that is driving an output.
4.1 I/O Configuration
The I/O Config tab displays the input and output points that are available per controller (see Figure 6-
36 on page 33 of this section). An operator can assign a descriptive name to every non-dedicated input
and output point and can identify if an input is normally-open or normally-closed. Grey input and output
point name fields indicate those inputs and outputs are dedicated by the controller and are not available
for link assignment.
The following steps describe how to configure an input point and an output point for window
monitoring as described above. For this example, controller 3 is a PXL-250 controller with an SB-293
Satellite board. This satellite board is configured for 2-door control. Using dedicated I/O, one input is
automatically configured for auxiliary RTE and one output is automatically configured for door held
open alarm annunciation. This leaves 5 inputs and 1 output that can be programmed into I/O links.
1. To configure input/output points, click on the Setup ⇒ System pull-down menu or click on the
button on the tool bar. Then click on the I/O Config tab.
2. Click on the arrow in the “Controller” field and a list of the controllers with available I/O points
appears. Scroll through this list and click on the controller which has the I/O points to be
configured. For this example, you would click on controller C003.
3. Locate an available input point for assignment. For example, locate input point 4.
4. To assign a name to the input point, click in the Input Point Name field for the desired input point
and type the name to be assigned to the point. For example, for Input Point Name 4, type Window
Sensors.
5. The normal state for this input is normally-closed. If a window is broken the input will be opened.
For the Mode of Input Point 4, click on the N/C radio button.
6. To assign a name to an output point, double click in the Output Point Name field for the desired
output point and type the name to be assigned to the point. For Output Point Name 4, type Window
Alarm.
7. The resulting window should appear similar to Figure 6-36 on page 33 of this section.
