Configure a contact

Use the System Design view to check and change properties for contacts.

When using a contact in your project, the physical change of the contact’s state might not always result in a single open-to-close or close-to-open state change, but rather bounce between states multiple times before the final state is reached.

To eliminate false notification of the contact state to the Control4 system, you can configure a 'Debounce Timer' to allow the system to see only a single state change.

In the System Design view, you can set this option in the Properties pane when you select a contact.

To set this option:

  1. Select the contact object from the project tree. View its properties in the Properties pane.

    2. Modifiable properties include:

    Invert Sensor—Depending on the sensor type, the controller sends a small amount of voltage through the sensor to close it, if for example when a door is closed with feedback indicating such. You use Invert Sensor if you want to feedback to be the opposite.

    Enable Debounce Timer—Sets an amount of time that lapses before the sensor triggers to on.

    Debounce Time(ms)—The amount of time in milliseconds before the sensor state changes to on.

  1. Check the Enable Debounce Timer box.
  1. In the Debounce Time(ms) (in milliseconds) drop-down menu, select to delay notification of the contact state (the default is 100 milliseconds).
