DI/DO Alarm Cable Requirements
Alarm inputs require 22AWG, 2-conductor,
stranded, shielded cable with drain wire. DO NOT
use twisted pair cables.
NOTES: Route all cables between the Expansion
1/O boards and the Superterm circuit board through
the wire guides provided on the Superterm cabinet.
Cable length between the DI/DO board and an
alarm device is limited to a maximum of 1000 ft
(305m).
Table 45 lists the cable gauge-vs-length
requirements for proper operation of the DI/DO
board and the alarm device.
