Expansion Boards and Accessories
Memory Expansion

Standard Memory : The standard version uses
a static 128K x 8 RAM (U61) to support
downloadable code, to provide working RAM,
and to support the card database.

256K Expansion : Static RAM (U61) expands
to 512K x 8 for support of 20,000 card holders.
Downloadable code is also expanded by this
option.

2 MB Expansion : An optional 2MB of RAM
may be added to the Superterm, providing
support for a maximum 200,000 card holders
(see Figure 2).
NOTE: Standard RAM (128K x 8) must be
installed along with the 2MB expansion board.
Digital Input/Digital Output (D1/DO) Board
The DI/DO Board supports up to eight, non-
supervised inputs and provides 16 relay outputs to
devices controlled by two state signals (see Figure
2).
Supervised Alarm Board
The Supervised Alarm Board supports 16
supervised alarms, with each alarm having five
states (normal, abnormal, open, short, and ground
fault).
Battery Backup
During power interruptions, the Superterm
continues operating for a maximum of 4 hours via
an on-board 7AmpHour back-up battery (standard
version) or a 12AmpHour back-up battery
(expanded version).
The backup battery provides DC power for all
Superterm access control and alarm monitoring
functions. After charging for 48-hours, the battery
carries the rated load for four or more hours. A
low-voltage battery sensing circuit protects the
Superterm by disconnecting the battery from the
main circuit if the battery discharges too much
current.
To provide adequate power for a minimum of four
hours, the standard Superterm 7AmpHour battery
allows the installation of only one DUDO board.
The expanded Superterm version includes a 12AH-
backup battery to provide adequate power for two
DI/DO boards for a minimum of four hours.
Power Transformer
The step-down transformer provides 14VAC to the
on-board linear power supply. An AC power
terminal block and grounding screw provide
connection points for the three incoming 120VAC
service lines.
