Rosslare Security Products 4 Door Expander
The Rosslare 4 Door Expander (MD-D04) is an access-control expansion module designed to increase the door capacity of Professional Scalable Controllers, including the AC-425 and AC-425IP. It allows installers to scale up an existing access-control system by adding support for additional doors without replacing the primary controller.
This expander provides connectivity for readers, monitored inputs, and door-control outputs, making it a practical addition for facilities that need to grow their secured-entry footprint. It is well suited for contractors and property owners expanding commercial or multi-door access deployments.
- 4 multi-format reader ports
- 4 supervised inputs, each supporting 4-state / dual end-of-line (EOL) configuration
- 4 Form-C relay outputs rated at 5A
