6.10 LTC 8569, LTC 8570, LTC 8571, LTC 8572 Series Code Merger Units
These series are control code merger and line driver units used to combine Allegiant
biphase control code from two (up to four with LTC 8570 and LTC 8572 versions)
systems for communicating to AutoDome Series cameras, receiver/drivers,
switcher/followers, and Allegiant Satellite systems.
The LTC 8569, LTC 8570 Series provides 32 separate outputs capable of driving up
to 256 remote devices. The LTC 8571, LTC 8572 Series provides 64 separate outputs
capable of driving up to 512 remote devices. Either “star” or “daisy chain” wiring
configurations may be used. The unit will accept signal input either from an Alle-
giant main CPU bay, LTC 8568/00 output, LTC 8780 biphase output, or an output
from another LTC 8569, LTC 8570 Series or LTC 8571, LTC 8572 Series unit. Multi-
ple units may be cascaded to obtain additional outputs.
6.11 LTC 8770 Switcher Follower Series
The LTC 8770 Series is an accessory unit which provides relay contact closures cor-
responding to cameras displayed on system monitors. The LTC 8770 may be config-
ured to follow manual activations, non-alarmed video, alarmed video, or both. Each
unit provides 24 relay contact outputs. In addition, six (6) functional operating
modes are available, including one user activated test mode.
6.12 LTC 8712 Series Console Port Expander Units
The LTC 8712 Series “expands” an Allegiant system's console port to permit up to
four (4) external computing devices to communicate with the system via RS-232
protocol. Any computing device that can normally communicate directly with an
Allegiant via its RS-232 console port can be used with this port expander. The exter-
nal devices may consist of PCs running the Allegiant system's MCS package, the
Allegiant GUI, access control systems, Allegiant RS-232 protocol keyboards, or
other devices utilizing the Allegiant system's Command Console Language (CCL).
6.13 LTC 8713 Alarm Port Expander Units
The LTC 8713 Series interfaces to the alarm port of an Allegiant system to permit
additional LTC 8540/00 Alarm Interface units to be connected. In a LTC 8500 sys-
tem, two (2) LTC 8540/00 units can be connected to a LTC 8713 Series unit provid-
ing up to 128 alarm inputs. In LTC 8600 systems, up to eight (8) LTC 8540 Series
units can be connected to three (3) LTC 8713 Series unit providing up to 512 alarm
inputs. In LTC 8800 systems, up to sixteen LTC 8540 Series units can be connected
to five (5) LTC 8713 Series unit providing up to 1024 alarm inputs.
