The figure shows a zoomed out version of a programmable alarm sequence. The upper waveform is 3 activations which do not exceed the Alarm Delay Time of 3 seconds followed by a fourth activation which exceeds the Alarm Delay Time of 3 seconds. When the activation exceeds the Alarm Delay Time the alarm mode is started and continues for the Alarm Hold Time, which in this case sounds the alarm for 4 seconds.
