Security I/O Wiring
Security I/O wiring is covered in the following subsections:
• "Supervised Input,"
"Relay Output," page 11
•
"Digital Input," page 12
•
Supervised Input
The Remote IO Security module has eight (8) supervised inputs, on two 6-position connectors (see
Terminals are labeled SI1, GND, SI2, SI3, GND, SI4 and so on. This means when wiring, two conductors are
typically landed to each GND terminal.
Each supervised input can monitor dry contacts, either normally-open (N.O.) or normally-closed (N.C.). One
end-of-line resistor pack
shows wiring of supervised inputs SI1 and SI2 used for monitoring door position and request-to-exit.

End-of-Line Resistor Pack
You must install an end-of-line (EOL) resistor pack at the monitored device for proper operation. Eight (8) EOL
resistor packs are shipped with each Remote IO Security Module. Each resistor pack has four leads:
New style: One red, one white, two black leads. Wire as shown in

Old style: Two white, two black leads. Wire black leads across contacts, and wire the white lead shown

internally connected to the black lead (common) to the "GND" input, and the other white lead to the "SIn"
input. See the detail in lower right of
Install each EOL resistor pack as close as possible to the actual monitored switch/contacts.
