How it Works

The Entraguard NPL II system uses an existing phone line as a means of direct communication with individual suites (rather like an intercom) to control building access. It does not dial out to a telephone company system. It replaces old or costly hard wire intercoms and eliminates monthly phone bills.

The Entraguard NPL II is ideal for housing authorities, apartment complexes, and office buldings. The panel is constructed of a vandal resistant 16 gauge stainless steel cover with backbox.
