16.2 Basic Alarm Response Mode
In the Basic alarm response mode, any or all of the monitors can be selected as
alarm display monitors. Each alarm can then be armed to display its camera(s) on
any set of armed monitors. Multiple alarms, on the same monitor, will sequence at a
1 second rate. Note that monitors and alarms can be armed and disarmed individu-
ally as required. Alarmed video automatically clears when the alarm input signal is

1 second rate. Note that monitors and alarms can be armed and disarmed individu-
ally as required. Alarmed video automatically clears when the alarm input signal is

16.3 Auto Build Alarm Response Mode
This mode uses a set of monitors as alarm display monitors. All system monitors
may be armed if desired. Each triggered alarm will display its alarm video on a dif-
ferent monitor, starting with the lowest numbered armed monitor. If all the armed
monitors are already displaying alarm video, subsequent alarms will build on the
existing alarmed monitors; and each monitor will sequence through its alarm videos
at a 1 second rate. Note that monitors and alarms can be armed and disarmed indi-
vidually as required. Alarmed video will automatically clear when the alarm input
signal is reset.

the keyboard. When the first video is cleared from the
the keyboard. When the first video is cleared from the
DISPLAY monitor, the next
alarmed video (“next” meaning the camera that enters an alarmed state second) is
displayed until cleared; operation continues in this manner. Note that alarms can be
armed and disarmed individually as required. Note also that all alarms must be man-
ually cleared; the presence of alarm video is not dependent upon the duration of the
alarm input signal to the system.
