Alarm Inputs in Satellite Systems

EN | 26
an operator requesting a satellite camera has a higher priority than at least 1 of the
existing operators, the requested camera will be switched. If the operator does not
have sufficient priority, they will receive an error message (i.e., error 81) via the sat-
ellite communication path, and their camera will switch to the Start-up camera spec-
ified in the Monitor Table.
Any alarm inputs to the main site, which have been programmed to activate cam-
eras located at satellites, will operate normally except when limited by the number
of trunk lines available. The software automatically determines trunk usage depend-
ing on the priority level of operators currently viewing satellite cameras. Alarm
inputs applied at a satellite site will not activate the alarm video at the main site. If
the application requires alarms located at a satellite to activate video at the main site,
the remote alarms must be brought back to the main site. If necessary, the main
site's LTC 8540/00 Alarm Interface unit can be remotely located via an RS-232 link.
Since the Alarm Interface capability is an integral part of the LTC 8100, LTC 8200,
and LTC 8300 Series, this is not possible if an LTC 8100, LTC 8200, or LTC 8300
Series system is being used as the main site system. If more than one satellite site
contains alarms, multiple LTC 8540/00 Alarm Interfaces can be remotely located.
The number of alarm interfaces which can be remoted is limited only by the capac-
ity of the main site system to support this capability.
