This intercom kit could be used for lots of other applications. The outside callbox has a automatic noise cancelling design for fairly loud environments but it does not work well for extremely noisy applications like truck scales.
Pressing the button on the outdoor callbox causes the inside handset to ring. You can then answer the phone and have a conversation.
If you initiate a call from the inside telephone by taking the handset off-hook, the outdoor callbox can be programmed to auto answer and a talk path will be opened between the callbox and the handset.
The callbox can be surface mounted or mounted on a gooseneck pedestal pole.
Both the outside and inside units get their power from the central hub. The power supply is included. Connections to the central hub require RJ-11 telephone connectors.
