3.2 Configuring Door Held Open Outputs
The Door Held Open (DHO) alarm uses a general purpose output on the SB-293/SB-593 Satellite board
to provide separate alarm annunciation for a door held open condition. Output 4 can be assigned as the
A-Door DHO alarm and output 3 can be assigned as the B-Door DHO alarm. When DHO is configured,
a door forced alarm continues to be annunciated on the original alarm output.
In this example, the DHO output will be configured for Door-B on a controller with a satellite board
configured for 2-door control.
1. Click on the Setup System pull-down menu or click on the icon on the tool bar. The Setup/
System window appears.
2. Click on the I/O Config tab. The I/O config window appears (see Figure 3-11 on page 17 of this
section).
3. Output points 1 and 2 correspond to the Door-B door lock and to the Door-B alarm output. They are
pre-configured and cannot be changed.
4. Output point 3 is available as either a general purpose output point (Output3) or as the DHO output
for Door-B (DoorB DHO alarm out). (Output point 4 is available as either a general purpose output
point or as the DHO output for Door-A. It is not configured in this example).
5. To configure point 3 as the Door-B DHO alarm output, click in the check box in the “Dedicated Y/
N” column beside Output Point 3. When there is a check in the box, the point is dedicated (see
Figure 3-13). The name changes to “DoorB DHO alarm out” to show the point has been dedicated.
To return this point to a general purpose input, click in the check box again and remove the check
mark.

6. Once the point has been configured, click on the button. If the point configuration is not
saved before clicking any other button or exiting the I/O config window, the configuration change
does not take affect.
7. Now update the access control network with the new information. Click on the button on
the tool bar (for details on the update process refer to “Update the Network” on page 35 in
section 5).
