635-INPUT MODULE – INSTALLATION OF BOARDS IN CONTROLLER PANELS
If you are not installing an Input Board, then skip this section.
PART 4.6.1 PREP STEPS -
BEFORE INSTALLING THE INPUT BOARDS
1.
You must know how many boards will be on each DSI 485 Channel (Section).
The last Input Board on the RS485-Section must be within the 4,000 ft. max line length.
A. INPUT BOARD:
•
MAIN PANEL: must have a
CPU board
and a
DSI board
; and Relay Boards on separate power supply.
•
SECOND PANEL: second or additional panels may have only the Relay Boards.
General Input (AMM)
Number of Relay Boards
Total Number of Relays
Per RS485 Section (port):
Up to
16 Boards
Up to
256 Inputs
per Section
Per DSI Board:
Up to
32 Boards
Up to
512 Inputs
per DSI Board
NOTICE: Each Input Board counts as 1 DEVICE toward the CPU’s 64-Device maximum – regardless of how many
inputs are connected to the board. This makes a max of 64 Input Boards per CPU.
However, you may have those 64 boards scattered across multiple DSI boards depending on the topology of your
building. The more DSI boards you put in the main panel, the less room for input boards.
Input Boards must be installed in a Multidrop configuration (daisy-chained) on the DSI RS485 Section.
