3.6 R/S/D/P-805 Extension Board Setup
There are four types of expansion boards as follows:
R-805 – The R-805 is an optional expansion board that adds 16 outputs to
the access control panel.
S-805 – The S-805 is an optional expansion board that adds 16 supervised
inputs to the access control panel.
D-805 – The D-805 is an optional door expansion board that adds 4
reader inputs, 4 outputs (Form C, 5 A), and 8 supervised inputs to the
access control panel.
P-805 – The P-805 is an optional expansion board that adds 16 supervised
inputs and 8 outputs to the access control panel.
Each extension board can be either located inside an ME-1515 enclosure or
can be installed directly on a wall using the included DIN rail attachment. Each
ME-1515 can contain up to two extension boards of different types.
One extension board can also be connected to the AC-825IP control panel
using the expansion slot (Figure 16).

When adding an expansion board to the expansion slot of the AC-825IP panel,
make sure the power to the control panel is off.
The system can support up to 12 expansion boards via OSDP.
Each ME-1515 is self-powered.
When multiple expansions are needed, we recommend using a daisy chain
connection.
