This is calculated by the
SG software based on
DRM board
address
– see
Step-11 for board
addressing.

- max 120 Relays per DSI Section
1 thru 15 –
Set via binary dipswitch
address on output board.

At the actual job site, the “max devices per section” can be less than what the system supports, due to physical factors such as
signal strength, physical topography of the building, or total line distance (4,000 feet).
**
R
emote readers
can be up to 500 feet from the DRM board. You can have any mix of reader types or card format.
The DRM Boards must be within the 4,000 ft max line distance for the DSI Board.

Install
Terminal Resistors
(or onboard Termination Jumpers)
at the extreme end of the RS-485 wire run
. When installing
resistors at the device, get as close to the device as possible. DSI board and Input Board have onboard jumpers - leave them open
unless the board is truly at the extreme end of the line.
