Connecting A Device To The Auxiliary Relay - CyberData 11113 Operation Manual

2.2.2 Connecting a Device to the Auxiliary Relay

The VoIP Indoor Intercom with Keypad incorporates an on-board relay which enables users to
control an external relay for activating an auxiliary device such as an electric door strike (see
2-1). The Intercom relay contacts are limited to 1 amp at 30VDC. 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.
