Thank you for purchasing the hands free kits art. HFX-700B!
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.
