Note: The alarm input must be a zero volt switch. Any voltage signals will damage the

dome. When multiple alarm signals are triggered the dome will respond to them, one by

one, and the response time interval will be 2 seconds. When more than one alarm signal is

received, the dome will not respond to “line scanning”, “tracking” and “self-learning”

functions.

Connect the alarm lines as Figure 25

4 channel alarm input activation & single channel alarm output

One of the special features of this dome is that it has four in-built alarm channels to call four

independent presets. This means that for example you may have a door contact and when the

contact is closed, it sends a 0 volt alarm switch to the dome on one of the four alarm channels.

The dome will then call a previously set preset position and lock the camera onto that position.

A single channel alarm out, allows the connection of an audible alarm, lighting or other warning

device. When more than one alarm input channel is utilised and activated, the dome will switch

to the next channel after two seconds. However once an alarm input channel has been activated,

the dome will remain locked to the preset position/s and will not resume a patrol, auto scan or a

record pattern until the alarm condition is cleared. However the Alarm Setup options in the

System Setup menu can be set to restart a tour if necessary.
