N-8640DS IP SUB-STATION PCB ASSEMBLY- 191 MAX. PER SYSTEM

  • UM : EA

The N-8640sb is an IP station kit that allows contractors to fabricate custom door stations. A rear cover and gasket are provided for outdoor applications. It provides full duplex audio to/from Master Stations. The N-8640sb is equipped with one control input and five control outputs (1 relay and 4 open collector) for integration with security or other 3rd party systems. An external speaker output provides .5W @8O. External or internal speaker priority is programmable. The -8640sb may be powered by PoE (recommended).
