You can program up to eight alarm inputs and two relay outputs per dome. Each alarm input can call up any
preset, macro (preset tour or programmed routine), or ShadowTour. The eight alarms are numbered from
1 to 8.

Programming tips for dome alarms

Legend IP domes do not handle alarms the same way as most other alarm equipment. You need to be aware of
the differences to manage the dome's inputs and outputs effectively. Here are some key concepts.
• You can set each alarm to have up to three components: a dome action (preset, tour, or macro), a
relay 1 action (on or off), and a relay 2 action (on or off). The relays can be used to trip such devices as
lights, doors, or alarm inputs on other devices. A dome action is not required. You could have an alarm
action one or both relays. An alarm with no action or relay settings does not affect dome operation.
• The priority that you set for the alarms determines which one is actioned.
• When an alarm action is set to a preset, tour, or macro, the camera will remain with that action until the
operator issues another camera command from the keypad. The Resume feature is disabled by alarms.
• Alarms are not held in a queue. Only the highest priority alarm that is activated is actioned. If several
alarms are activated at the same time, then the one with the highest priority is actioned. After that
alarm has finished, the next highest priority alarm will be actioned only if it is still active. If a higher
priority alarm is activated while a lower priority alarm is being actioned, then the higher priority alarm
overrides the lower priority alarm and is actioned instead. After the higher priority alarm has finished
being actioned, then the lower priority alarm will have its action restarted. But only if it is still active.
• You do not need to acknowledge dome alarms in the same sense as required by typical alarm
equipment. To move the camera from the position of the alarmed action and reenable the Resume
feature, however, you do need to issue a command from the keypad. An alarm that has been triggered
and cleared will not be recognized again by the dome until another alarm is triggered, or a command
from a keypad is received.
• Faulty dome alarms cannot be shunted. If you cannot readily repair the alarm wiring and/or contact of
a faulty dome alarm, you can lower its priority and program the alarm box to display only the highest
priority alarms, or you can reprogram the faulty alarm with no action or relays.
• The only time you need to "clear" a relay state is when you have set a relay with the Infinite duration.
• If you have a relay set to the Infinite duration, you can clear it one of three ways. One, you can
manually clear it by selecting a Relay Off button on the Relay State page. Two, you can automatically
clear it by using another programmed alarm number that sets that relay with a duration of at least five
seconds. And three, you can clear it with a remapped preset command that activates a macro from the
keypad. To remap preset commands, see
scenario would be Alarm 1 being used with a badge reader to open a door and Alarm 2 being used with
a PIR on the other side of the door to lock the door. Alarm 1 would energize a relay with an infinite
duration to open the electronic door lock and Alarm 2 would deenergize the relay with at least a five-
second duration to close the electronic door lock.
• If you select the Relay 1 on or the Relay 2 on button on the Relay Status page, and select OK, then
you are programming the dome to activate either or both of these relays each time the dome is powered
up. The relay action becomes a default.
• Even though you can create an alarm block title and alarm titles that are up to 60 characters, we
suggest limiting titles to 15 characters to reduce the size of the video obstruction.
