Supervised Alarm Board Accessory
Connections
The Supervised Alarm board provides terminal
strips for 16 alarm inputs. The alarm inputs are
connected to the Supervised Alarm board using
connectors J4 through J19 (see Figure 40).
NOTE: Route all cables between the Supervised
Alarm boards and the accessory alarm inputs
through the wire guides provided on the Superterm
cabinet.
Table 41 lists the connections between the
Supervised Alarm board and the alarm inputs.

CAUTION
A When powering-up the Superterm system, at
least one of the supervised alarm inputs must be
in a non-open condition. The Superterm will
not be able to initialize the Supervised Alarm
board if all of the inputs are open.
Supervised Alarm Cable Requirements
Alarm inputs require a 22AWG, 2-conductor,
stranded, shielded cable with drain wire between
the alarm sensor and the Supervised Alarm board.
DO NOT use twisted pair cable.
Table 42 lists the cable gauge-vs-length
requirements for proper operation of the
Supervised Alarm board and the alarm sensor
device.

Supervised Alarm Board Address Selection
Jumper
Proper operation of the Superterm and any
Expansion I/O boards requires that each Expansion
1/O board have a unique address.
The Supervised Alarm board has an on-board
Address Selection jumper that identifies the board
to the Superterm (see Figure 40).
Setting the Address Selection Jumper
The I/O signal definitions (numbers assigned to
inputs and outputs) are determined by the
Expansion 1/O board address settings. Refer to the
section on 1/0 Signal Mapping, page 62).
1)
Install all of the Expansion 1/0 boards in the
Superterm Cabinet before setting the Address
Selection jumper.
2) Determine the location of the Expansion I/O
board in the order,
from right to left, that the
Expansion I/O boards are mounted (see Figure
40).
3) Set the Supervised Alarm board Address
Selection jumper accordingly.
NOTES: The Address Selection jumper has four
possible positions, X1, X2, X3, and X4. Position
X4 is reserved for future use.
Do NOT use position X4 when setting the Address
Selection jumper.
