Install the HTS 811-0 indoor telephone inside the building and connect it to the transformer TR 603-0. Use the front nameplate to label the call button and configure the info sign as needed. When a visitor presses the call button, communication is established via the integrated loudspeaker; the resident can speak, open the door using the release button and adjust the indoor volume using the external control.
Usage recommendations
For reliable operation, ensure correct 1+n wiring and secure mounting. When expanding the system with additional indoor stations or secondary signal units, follow Siedle wiring and power guidelines and verify transformer capacity. For outdoor installations, position the door station to minimise direct exposure to water and use appropriate sealing around the mounting edges if necessary.
