EXPANSION BOARD CONNECTIONS
Superterm CIC1800 / CICP1400UL 66
DI/DO Alarm Output Connections
The DI/DO board incorporates 16 relays (K1
through K16) that provide 16 "Form C" contact
sets. Connections to these relays are made through
the Alarm Output terminal strips labeled J 1
through J 16 (see Figure 45)
.
Each contact set consists of a normally open (NO),
a common (C), and a normally closed (NC)
connection point.
Where Jxx is to be interpreted as J1-J16,

Jxx-1 = Normally Closed

Jxx-2 = Common

Jxx-3 = Normally Open
NOTE: The contact rating is 3 Amperes
(resistive).
In order to reduce electrical noise generated by
controlled devices such as electric door strikes or
magnetic locks, a Metal-Oxide-Varistor (MOV)
has been placed across each of the relay contact
sets.
NOTE: These MOVs have a voltage rating of 56
Volts DC.
Maximum efficiency of the Superterm requires
installing additional MOVs across each door strike
or magnetic lock, as close to the device as is
possible.
NOTE: Additional MOVs are available from
Continental Instruments as part number 480-1048,
Rv0005.
CAUTION
Door strike wiring must not be placed in the
cables, bundles, or conduit with other wiring.
Transients produced by these wires may cause
unreliable operation of the Superterm.
Maintain a minimum of six inches distance
between door strike wiring and all other input
wiring.
DI/DO Alarm Board Address Selection
Jumper
Proper operation of the Superterm and any
Expansion I/O boards requires that each Expansion
I/O board have a unique address.
The DI/DO Alarm board has an on-board Address
Selection jumper that identifies the board to the
Superterm (see Figure 45).
Setting the Address Selection Jumper
1) Install all of the Expansion I/O boards in the
Superterm Cabinet before setting the Address
Selection jumper.
2)
Determine the location of the DI/DO Alarm
board in the order,
from right to left , that the
Expansion 1/O boards are mounted (see Figure
44).
3)
Set the DI/DO Alarm board Address Selection
jumper accordingly.
NOTE:
The Address Selection jumper has four
possible positions, Xl, X2, X3, and X4. Position
X4 is reserved for future use.
Do NOT use position X4 when setting the Address
Selection jumper.
