Product specifications

The Acknowledge Mode menu determines whether an alarm is acknowledged
manually by the operator, momentary so the alarm remains active until the alarm
state is eliminated, or automatically after a predetermined period of time (up to 89
seconds). In simplex mode, the dome should be programmed to acknowledge
alarms in some way to force the dome into reporting the alarm to the system.
Note: In simplex mode, be sure to program the dome to somehow acknowledge
alarms. The system will stop responding to subsequent alarms. In duplex
mode with a NOVA system, never set up an alarm set and reset action. The
system will call up the reset action before the set action could finish
because NOVA systems immediately acknowledge alarms. It is
recommended that the NOVA systems be used for alarm processing.
The next two menus program what happens during an alarm event. Each alarm is
actually two events, set and reset. In many cases, we can have 4 alarm functions
per dome. Set Actions occur when alarms are triggered. In our example this
occurs when the door is opened. The Reset Actions occur when the alarm
conditions are removed, in this case when the door closes again. Since each
action may be programmed individually, we can handle many more functions than
are immediately apparent.
The Set Actions menu calls up a sub-menu for each of the four alarm inputs. The
Reset Actions menu calls up an identical sub-menu for the reset actions. Choices
for action upon triggering the alarm are as follows:
• No Action — Nothing happens on this alarm action.
• Preset — Allows any one of the 79 dome presets to be called.
• Turn On AUX — Allows the Relay Driver to be turned on.
• Turn Off AUX — Allows the Relay Driver to be turned off. Please note that
a Set Action can turn on the driver, while the corresponding Reset Action
can turn off the driver.
• Tour — Activates one of the 8 (22X and 23X) or 4 (18X) preprogrammed
tours. Since a tour consists of up to 32 steps, and a tour can call other
tours, by combining tours with alarm actions, multiple actions can be
triggered from a single contact closure.
• Autotour — Activates one of the 2 preprogrammed autotours. An Autotour
is a tour created dynamically with the pan, tilt and zoom functions. This
function is not available for the 18X version.
The final menu choice available on the Alarm Input Controller menu is to
Program Alarm Titles. This function and sub-menu are also available from the
Source Titling menu and will be reviewed in that section.
