Newsletter 02/2021: Start the year with Siedle
Dear Madam or Sir

Start 2021 by upgrading older intercom systems to enable mobile door communication: Our IQ HTA in-house telephones for 6+n systems are now available from stock.

Here’s to a healthy and prosperous 2021!

Best regards,
Your Siedle Team
The Siedle IQ HTA in-house telephone is now available. In conjunction with the Siedle app, existing systems with 6+n from 1952 onwards can be upgraded to enable mobile door communication. Without a gateway, tedious configuration or structural changes.
