The DUO IP/LTE module in UNIVERSAL mode can connect to any security system to perform basic alarm notification and status functions, and has both IP and LTE reporting capability built right in.
Add an UNO4 module and use the PGM output to perform remote Arm/Disarm functions as well as add 4 additional inputs.
In UNIVERSAL mode the DUO IP/LTE could also form the basis of a small, standalone, security system, with all the power of a full-size panel.
It can be simply used as a tiny 2-zone system or it can be expanded by adding either the UNO4 or UNO8 modules as needed to grow the system out to as many as 30 zones.
