9. Introduction
The D-805 is a 4-door expansion board for the AC-825IP access control
panel.
The D-805 can be installed directly on top of the AC-825IP or installed
on the wall and fitted on a DIN rail as an expansion board with RS-485
communication to the AC-825IP OSDP/RSDP-Bus (S-Bus).
The expansion board supports four Wiegand readers and four doors
with two supervised inputs, including one relay output for each door.

11. 10BWiring Instructions
The reader terminal supports the reader's two data lines. For Wiegand
readers, these are data lines D0 and D1. For Clock & Data readers, D0
is the DATA line and D1 is the CLOCK line.
There is also support for a tamper signal input from the reader and for
one LED control output to the reader.
Proximity and keypad readers are supplied with a limited cable. The
color of the cable cover represents the cable’s function.
In general, the cable length should be no more than 150 m (500 ft)
with an 18 AWG cable. Refer to each reader's installation guide for
specific details.
To wire the D-805 expansion:
1. Connect the RS-485 communication terminal block to the AC-
825IP OSDP/RSDP-bus (S-bus) using daisy chain methodology as
shown in Figure 6.
For RS-485 communication, use a maximum of 1,200 m (4,000
ft) cable length and minimum 22 AWG.

When using AC-825IP and D-805 with AxTraxNG, define input and
output types from the Groups element in Tree View. Input and output
functions are defined using the Links element within each Panel tree
menu item.
