Napcoˇs UL864/UL1610-listed NetLink Receiver is an advanced, rack-mounted receiver enabling cost-effective, secure Internet alarm reporting designed to address the increasing need for UL central stations to adopt new receiver technologies to combat the widespread adoption of voice over internet protocol (VoIP) services. While in full compliance with UL Central Station applications, requiring primary and mirrored, backup receivers, two NetLink UL Receivers can be installed at the same cost as a single traditional receiver. Both NetLink TCP/IP UL Receivers interface with the conventional CS automation system and are simply connected to each other with a network crossover cable, where the secondary mirrored receiver serves as a Hot Backup, duplicate receiver. The NetLink UL TCP/IP Receivers feature two modes of operation: Automatic Mode, where alarm signals are sent normally to the automation system for processing; or Manual Mode, used when direct operator interaction is desired, accomplished through an easy, menu-driven keypadstyle alphanumeric interface on the face of the receiver.
