Easy Installation

The Cellular Connection Box can be quickly and easily installed on all Standard and Access Plus 1800 Series Telephone Entry Systems.




Easy Activation

It’s just as easy as activiating a cell phone – no trenches to dig, no wiring to run, no telephone lines or ethernet cables to maintain.

Wide Coverage

Once installed, the 1800 Series Entry Systems use a 4G LTE* cellular connection for voice communication, instead of the traditional copper phone line.

*Where available in the United States

PC Programable over Cellular

Additionally, the 1800 Access Plus and 1830 Series devices also use the cellular connection for programming the system from your PC.
