Supplies different ring patterns for outside and inside calls. Preserves minimum communication during power failure. May cascade together for extended usage. The FX207 supports one doorphone. When the user presses a button on the doorphone, the phone system rings all phones with a distinctive ring.
Any phone can answer and talk, two-way, with the person at the door.
You must have both the doorphone and the doorphone adaptor to use the doorphone. Wiring is simple, requiring only one pair of telephone wires. The optional rechargable battery maintains system memory and setups during a power failure for up to 5 hours. Note that this battery does not power the whole system, it just keeps the memory intact.
