# True state and Long State button

## **True state button**

True state is a crucial parameter designed to address issues related to false button presses caused by interference in your system. When configured, this parameter dictates the signaling delay to the Central Unit (CU) once the button is pressed. This delay serves as a protective measure against erroneous inputs—specifically, if a false press occurs within a duration shorter than the time specified in the True State parameter, the information will not be transmitted to the CU. Consequently, the unit will intelligently disregard such short-lived signals, ensuring that only valid button presses are acknowledged and acted upon. This feature enhances the reliability and accuracy of your system, especially in environments prone to interference, offering a more robust and secure user experience.

## **Long state button**

Long State plays a pivotal role in mitigating challenges associated with BUS interference and slow communication in your system. Specifically, this parameter sets the signaling delay to the Central Unit (CU) when a button is released. In installations where BUS communication faces sluggishness due to interference, the Long State parameter proves invaluable.

In scenarios where a button press is short and the BUS communication is slow, there might be a risk of the unit not being able to transmit the information to the CU in a timely manner, especially regarding the acknowledgment of a press and subsequent release event. To address this concern, the Long State parameter comes into play. It extends the press time by the specified value, allowing the unit to compensate for the sluggish BUS communication. This ensures that the CU receives the necessary information regarding the button press and subsequent release, even in situations where the standard communication speed may be compromised. As a result, Long State contributes to the reliability and responsiveness of your system, offering a solution tailored to environments with BUS-related challenges.
