¾ Alarm 1-4 Types: These fields represent what to do when a signal is

received from the alarm board connector. There are two types of alarm
signals. The first is N.O. which stands for Normally Open circuit. The
Second is N.C. which stands for Normally Closed circuit. The default
setting is N.O. This option would be set according to the type of alarm
input connected to the alarm board. For example if you connected a door
sensor which was a Normally Open circuit you would set the alarm type to
N.O. To change this, simply use the arrow keys on the DVR which also
represent the channel 1-4 keys (These are the top four buttons). Use the
up and down arrow keys to make your selection.

ƒ Please note: Refer to Appendix D for more information about setting

up the alarm board.

¾ Alarm Reset Type: This field is to set the alarm signal back to normal. If

you have a N.O. alarm in the alarm types you would set it back to N.O. If
you have a N.C. circuit you would set it back to N.C. To change this,
simply use the arrow keys on the DVR which also represent the channel 1-
4 keys (These are the top four buttons). Use the up and down arrow keys
to make your selection.

the up and down arrow keys to make your selection.
