Connection of intercoms
The lock is connected to Sigur controllers using the same ports as to the intercom. In this case, the intercom will lose direct control over the lock and will communicate the command to open the door via the controller.
There are two most commonly used intercom connection options:
the lock and the intercom are connected in a series circuit to the power supply unit and the lock is controlled via a relay built into the intercom
voltage is supplied to the lock directly from the intercom
The recommended connection diagrams are usually provided in the intercom manuals.
Control of the lock by the intercom relay
This is the most common type of connection. You can find connection diagrams for Sigur controllers in the manuals on our website.
Connection of an intercom supplying the lock
In this case, the circuit connecting the lock is not just closed or open, it supplies voltage directly.
If the intercom is configured to operate an electromechanical lock, the terminals of the intercom relay are normally open and no additional settings are required.
If the intercom is configured to operate an electromagnetic lock, the terminals of the intercom relay are normally locked and minimal settings are required to reassign terminals in Sigur software.
Integration with CCTV IP cameras
If an RTSP-enabled video intercom (real time video streaming) or IP cameras logically connected to checkpoints are used, access events can be linked to the relevant photo or video footage, which can be accessed in the archive
