Description
The Allegiant LTC 8900 Series is a state-of-the-art video switching and control system for
indoor use only. It is the highest-capacity system in the Allegiant family. The system can switch
and control up to 4096 cameras to 512 monitors. It is also compatible with all the existing
accessories currently available in the Allegiant product line. Various system capacity
configurations are illustratedin , page 68 through , page 68.
Features
The LTC 8900 system can be purchased in either one of two design configurations: standard
and redundant. The standard configuration includes the LTC 8904 Series type CPU, which
contains a single CPU module and a single power supply. If maximum reliability is required,
the system can be purchased to include the LTC 8901 Series CPU which contains dual CPU
modules and dual power supplies. This redundant system design option includes an industrial
model PC, which enables the system to provide automatic switchover in case of failure of the
primary CPU module or of the CPU power supply.
The LTC 8900 Allegiant series systems can accommodate multiple operator keyboards and a
computer system console. They can also accommodate 2048 alarm points. All 2048 alarm
points are available through RS-232 command input; up to 1024 alarm points are available
through contact closure inputs using LTC 8540/00 alarm units and LTC 8713/00 Series port
expander units. In addition, the Allegiant Series have a Satellite configuration capability
through which the system can communicate with up to 256 remote combinations of Allegiant
Series switchers. In standard system configurations, the user can add a Windows®-based PC
to simplify programming of the system using either the supplied LTC 8059 Master Control
Software for Windows package or the optional LTC 8850 GUI software package. In the
redundant design configuration, the system is programmed and continuously monitored using
the supplied LTC 8943/95 System Controller Pentium® PC.
Using the PC-based software, user passwords can be utilized, providing an added measure of
system security; various lockout tables restricting user access to cameras, monitors,
keyboards, and remote camera control are easily programmed using the PC-based software
package. The PC software also supports up to 128 different time-activated events, providing
automated control of video sequencing, monitor message broadcasts, receiver/driver
functions, sophisticated alarm control, powerful system macro capabilities, and several other
functions.
Even with its sophistication, the Allegiant LTC 8900 system is designed for the novice user.
The ergonomic keyboard design contains many user-friendly but powerful functions. A user
can choose from up to 256 sequences that are stored in memory, select any of the cameras to
view on any of the monitors, and take exclusive control of remote pan/tilt camera functions
right from the keyboard. Each monitor can display a system status overlay showing alarm
status, sequence conditions, time/date, and camera information.
The Allegiant LTC 8900 Series systems represent a dramatic breakthrough in CCTV switcher/
controllers, and are backed by years of expertise in designing and manufacturing closed circuit
video equipment.
