The NAPCO NetLink NL-MOD-UL is a device that allows the reporting of alarms over a TCP/IP based (Intranet or Internet) network. Alarm reporting, previously performed via Telco only, can now be performed over both a TCP/IP network and/or Telco, or via the TCP/IP network as a backup. The NLMOD-UL is housed in a separate plastic enclosure, and is connected to the Local Download receptacle for the GEMP816 / P1632 / P1664 / P3200 / P9600 and X255 Napco control panels, and is connected via the parallel inputs with the MA3000 and other file alarm control panels.
