The Control panel supports fire extinguishing Hold (EN 12094) / Abort (UL 864) buttons.
A device defined as a fire extinguishing Hold (EN 12094) / Abort (UL 864) button delays
fire extinguishing activation as long as the button is pressed.
Releasing the button will resume the countdown that had been suspended while the
button was pressed, if the countdown had not ended. If the countdown had ended, fire
extinguishing will activate within 5 seconds after the button was released.
Pressing the Extinguishing activation call point overrides this function.
See chapter 8 on page 41 for a detailed explanation about device programming.
