After buying several intercom systems over the last 30 years, I've seen all kinds of problems with them.
Some squawk, some have static, some the call buttons don't work half the time and they don't work at
all in a power outage. If something goes wrong you need an electronics degree to fix them, so they get
thrown away. This one is easy to build and if ever you have trouble it's a simple fix.
You will get a parts list and step by step instructions and plenty of drawings for each step to wire it up.
All you need is a wire stipper/cutter and a screwdriver.
