Intercom function
There are three kinds of intercom function available in the
CHALLENGER PRO system.
1. Guard Unit Call
A Monitor can be assigned to be the guard unit Monitor by setting on the OSD screen of the
Monitor. When the user's Monitor is in standby, press call button or intercom button, the intercom
page will show up on the screen, than select and confirm 'Call Guard Unit' item, and the Monitor
will call the guard unit Monitor, when the guard unit Monitor answers the call, conversation with
the guard person is started.
2. Inner Call
When multi Monitors are installed in one apartment, inner call is available. Note that all Monitors should have the
same User Code, and the Master and Slave address should be set on the Monitor(see page 40 for more detail) .
When the Monitor is in standby, press call button or intercom button, the intercom page will show up on the screen,
than select and confirm 'Inner Call' item, and other Monitors will ring at the same time. When any Monitor answers
the call, other Monitors will stop ringing and go back to standby state.
3. Intercom Call (Namelist)
The namelist intercom is for apartment to apartment calling. The user in one apartment can call other apartments by
selecting the name on the screen. In this way, it's no need to renumber the ID(User Code or room address) of the
other users. A complete namelist of all the users in the system can be upload to the Door Station by the
CHALLENGER PRO CONFIG software, and then the Door Station will send the namelist to all Monitors.
