Thank you for purchasing the hands free kits Art. HFX-7000M!
This intercom system uses 2-wire installation and allows you to identify and
communicate with callers at the door, from the security and convenience
of any room in your home or office. Visitors activate the system by pressing
a call pad on the external unit, which sounds a doorbell chime as well as
turning on the inside "hands free video monitor".
A two-way intercom then lets you speak with visitors after first visually
identifying them.
It consists of a hands free monitor station and an external unit.
This kit is capable of expanding up to a total of 4 indoor monitors and 4
external units.
