First out.
Displaying the visual device in intermittent flashing pattern and activating the
audible devices until the first function is reset distinguish the first alarm. The
acknowledged first alarm is distinguished by changing the visual display as slow
flashing. Subsequent alarms follow the basic sequence A. Because the Reset
pushbutton is used to reset the first out function, Acknowledge can be used to
sequence the subsequent alarms through a standard sequence. This makes it
possible to distinguish the new subsequent alarms from the previously
acknowledged subsequent alarms. Also the subsequent alarms lock in until they
are acknowledged. Once acknowledged, they can automatically return to normal
state when the input points return to normal.
