The Intercom relay contacts are limited to 1A at 30 VDC. The Intercom relay activation time is selectable through the web interface and is controlled by DTMF tones generated from the phone being called. The DTMF tones are selectable from the web interface as well.

Note The three digit code for the auxiliary relay must be sent in conformance with RFC2833 DTMF generation.
