What the existing connection tells
A living door, common entrance and business gate have different requirements. The most important thing is not only whether ringing the doorbell stops, but whether residents and visitors can safely go outside.

Intercom in case of power outage and emergency opening
An intercom can fail during a power outage, but the consequences for access and exit vary greatly depending on door hardware.
The technical choice
Determine which lock is present, how it responds to voltage loss, and which mechanical opening remains available. Include existing fire safety or access agreements in the conversation.
What you let me arrange
Choose a suitable emergency provision or clear mechanical solution where necessary. Do not connect a lock without knowing the safe exit and the desired locking during a malfunction.
Delivery to the door
Perform a controlled test where regular power supply is removed. Check output, recovery after tension release, and whether users understand which action applies in an emergency situation.
Frequently asked questions
