2.3.4 Digital Input
The Digital Input Board (
) provides connections for up to eight dry contact switch inputs. The two
position connectors are identified as DI-1 through DI8. The board plugs into a Carrier Board to complete a
Digital Input Stack.
The Digital Input board enables the user to connect the outputs from foreign devices including switches or
alarm only gas monitors. Digital inputs require an end of line 4.7K resistor for supervised monitoring.
The board polls the status of the inputs and converts data into the common serial protocol for
communicating with the SBC. The Digital Input status can be used in Sentry Commander logic relay
management algorithms. The board includes:
(1) Eight Digital Input field connectors to support addresses DI-1 through DI-8
(2) Factory installed ribbon cable connection for power, inter-stack and SBC communication
Digital Input Stacks can be installed in any stack position in the controller, generally the Stack 2 or Stack
3 position. A maximum of two Digital Input Stacks are allowed per standard channel controller.
NOTE: Digital Inputs must be conventional initiation type devices with dry contacts and must be
located in the same room.
