The Main site system must be programmed via the MCS LTC 8059/00 or the LTC 8850/00 GUI to identify camera trunk line inputs as well as remote satellite cameras. All systems must be configured with no duplicate camera numbers any- where in the system. The installer should verify that the camera numbers pro- grammed into the
In addition, it is recommended to program Lockouts for all system keyboards so that they do not have access to unused monitor outputs. This prevents operators from inadvertently selecting a satellite camera on a
Keyboard User Function 41 (See Chapter 14, “User Information,” on page 38) offers additional programming options if a
Any alarm inputs to the Main site configured to activate satellite cameras operate normally except when limited by the number of available trunk lines. The software automatically determines trunk usage, depending on the priority level of operators currently viewing satellite cameras.
Alarm inputs applied at a satellite site will NOT activate alarm video at the Main site. If the application requires alarms located at a satellite to activate video at the Main site, the Main site's LTC 8540/00 Alarm Interface unit must be remotely located. Multiple LTC 8540/00 Alarm Interfaces may be remoted via the LTC 8713 alarm port expander accessory, located at the Main switcher site in LTC 8800 and LTC 8900 systems. Up to two (2) LTC 8540/00 alarm interfaces with a LTC 8713 alarm port expander can be used in a LTC 8600 system. One LTC 8540/00 can be used in LTC 8500 systems. Since the LTC 8100, LTC 8200, and LTC 8300 Series contain an integral alarm interface, the remote alarm interface application does not apply.
A unique time and date synchronizing feature provided in the Time Event Table of the MCS or the GUI Software may be programmed into the Main site switcher. This permits periodic synchronizing of the time and date to all remote switchers in the system based on the Main site's clock.
