Please be ready to provide the following information:
1. Desired system camera capacity.
2. Desired system monitor capacity.
3. AC line voltage input (120VAC, 60Hz or 230VAC, 50Hz).
4. Specify if either a standard system or a system
containing a redundant CPU/power supply conguration
is required.
5. In systems utilizing a redundant CPU and less than 65
monitors, you can also specify if the design should
employ a redundant system configuration. This type of
configuration would force a design that includes at least
2 monitor bays. The use of 2 monitor bays reduces the
chance of a single point failure causing a loss of all video
signals, even if the system’s redundant CPU remains in
operation.
6. Video input looping requirements.
Optional accessories:
If external contacts will be utilized to activate alarm video
switching, LTC 8540/00 Alarm Interface Units and, if
necessary, LTC 8713/x0 Alarm Port Expander Units can be
added to the system. Follow the table below to determine
the appropriate quantities required.
LTC 8900 Series
For extremely large size, modular based Allegiant
systems.
• Modular construction utilizes multiple video matrix bays
and video modules to realize full matrix crosspoint
switching of 4096 cameras by 512 monitors.
• Standard single CPU or redundant dual CPU / dual power
supply system configurations available.
• Optional external alarm and remote control signal
distribution accessory devices available.
• Full control and programming by up to 64 keyboards.
• RS-232 Serial port for external PC interface support.
• Integral 2-U and 6-U high rack enclosures.
• 2-digit site and 4-digit camera identication mode.
Ordering Information:
Because of the numerous main system components that
comprise a typical LTC 8900 series system, parts list
quantities are determined by Bosch Security Systems
representatives. Please contact your local Bosch Security

Interface Unit when quantities are greater than one. The
TC120PS power supply is used for 120VAC AC line sources,
and the TC220PS is used for 230VAC line sources.
