Why install a second intercom?
Having only one intercom at home may be insufficient if the house has multiple floors, areas far from the entrance, or if there are elderly people or those with reduced mobility. Adding a second intercom allows you to answer calls from anywhere in the home without unnecessary movement.
Options to add a second intercom
Option 1: Additional monitor or phone in parallel
The most common solution is to connect a second monitor or phone in parallel to the first one, using the existing wiring. In 2-wire systems, this is possible with Tegui expansion kits, such as the EasyKit 367910.
Option 2: Additional universal phone
In 4+N wire installations, the Tegui Universal Phone T-71U can be easily installed as a second terminal without needing to modify the main installation.
Option 3: Mobile opening as a second point
If your monitor is WiFi compatible (like the Tegui T-72), you can use the Tegui Connect app on your smartphone as a second control point, without needing to install additional hardware.
