To deactivate the alarm on the Polon-Alfa 4000 control panel, press the backlit ‘ACKNOWLEDGEMENT’ button. This cancels the fire alarm at the control panel. However, fire alarm signaling cancellation requires at least 2nd level access authorization.

    ID-E342-001GB Depending on the expected fire types, it is possible to use various combinations of smoke (ionization, optical) and heat detectors. An individual fixed temperature detector actuation in a zone evokes also an alarm in this zone and the 2nd stage fire alarm at this control panel. Note: The 4043 model range detectors (DIO-4043, DOR-4043, DUR-4043, and TUN-4043) are unable to operate in a zone programmed in an interactive alarm variant.
