995004: Universal Expander
The Universal expander is connected directly to the Concept 485 LAN. Up to 64 expander modules may be installed in a single panel system.



The Universal Expander enables the installer to configure an Access 4000 System to virtually any application.
The number of Expanders and the combinations of Zone Inputs, Auxiliary Expanders and Relay boards offer infinite possibilities.
The Universal Expander Module connects to either a Concept 3000, Access 4000 system to provide an additional 16 Zone inputs, 8 Auxiliary outputs and 2 Siren drivers. Up to 64 Expander modules can be installed in a Concept 3000 or Access 4000 system, depending on the memory option fitted to the Control Module.
