Emergency release on the garage door: safe opening in case of power failure
No side entrance, power outage – now what? Here's the direct way: Use an external emergency release, choose a sensible battery backup, and make your system self-sufficient.
Introduction
In the event of a power outage, a good emergency release cleanly disconnects the drive from the gate – allowing you to open it manually. A suitable battery backup ensures you remain able to operate the motorized gate. This guide explains selection, sizing, and installation basics. It also includes clear links to tested products and a mini-news item based on our practical experience. The goal: access at any time – safe, quiet, and stress-free.

✅ Advantages & Benefits
External emergency release opens manually – even without a side door.
Battery backup bridges outages – gate remains motor-operated.
Clean decoupling, controlled running, reduced material load.
⚙️ Technical Background
Lock in the gate leaf, pull cable to the drive head. Pulling the cable separates the drive and the gate – the balanced gate can then be moved manually.
24V battery units provide temporary power to the drive. Capacity determines the possible cycles – IP20 for indoor use, IP65 for weatherproof installation.
Work on springs/ropes should only be carried out with expertise and tools. Emergency release/backups are not critical; however, please follow the instructions.
🧭 Selection & Decision
- No side entrance? External emergency release is mandatory.
- Frequent use? Plan for a larger battery capacity.
- Outdoor mounting location? IP65 enclosure preferred.
- Old system? Consider an external receiver/upgrade.
