The Dry Contact I/O Accessory provides a hardware interface for connecting the host device of a Network Management Card with peripheral devices. The Dry Contact I/O Accessory includes the following components:
Inputs that are labeled "Zones A and B" for two dry contact devices
One 12V, 25mA power output that is labeled "Pwr"
One Form C relay that has relay outputs labeled as "Output"Dry Contact I/O Accessories connect to universal I/O ports on your Management Card. Through the Management Card software interface, the user specifies which alarms will cause a change in state of the Form C relay. The user also may set the actions that will occur at the host due to a change in state of the dry contact devices.Installation

(1) Screw terminal block (2) Dry contact I/O accessory (3) CAT-5E RJ-45 patch cableInstall the Dry Contact I/O Accessory (2) using the procedure listed below:
Connect the Dry Contact I/O Accessory to the screw terminal block (1) .The screw terminal block accepts 16 AWG to 28 AWG wires.
Connect the CAT-5E RJ-45 patch cable (3) to the Dry Contact I/O Accessory (2) .The CAT-5E RJ-45 patch cable is used to connect the Dry Contact I/O Accessory to a universal I/O port on a Management Card.Note: The Management Card must have application firmware v5.0.2 or greater.Connecting Dry Contact Devices to the Zone A and B Terminals on the Screw Terminal Block
The sensing voltage available on the Zone A and B pins of the Dry Contact I/O Accessory is nominally 5VDC at less than 1mA, referenced to system ground.
