Positive Alarm Sequence
The Velocity MMP is equipped with a positive alarm sequence that will program a delay to the NAC’s, Alarm relays and Auxiliaries for a
period of between
1-15 seconds
. If the alarm is acknowledged, it will silence the piezo sounder and start a timer which will prevent
activation of these outputs for an additional time duration which can be user programmed between
1-180 seconds
. After the
programmed delay, if the source of the alarm is not cleared, all the outputs will activate. If the alarm is not acknowledged or reset
during the first time delay of 15 seconds, all the appropriate outputs will be activated. If a second alarm occurs during either time
delays, or if a manual alarm is activated, this will immediately cause the activation of the appropriate outputs.

Go to the engineer menu, and select the Delays Icon
