Don't Get Stuck! How to Operate Your Roller Shutter During a Power Cut or Malfunction

Understanding Your Roller Shutter's Manual Override Options

Modern security roller shutters are designed with safety and convenience in mind, and most electric models come equipped with a manual override system. The type of override depends on the shutter's design and motor.

1. Crank Handle Override:
   • Common For: Smaller to medium-sized commercial and domestic shutters, including garage roller doors.
   • How it Works: Usually involves a small eyelet or loop accessible near the motor or on the shutter box. You insert a manual crank handle and turn it to raise or lower the shutter.
   • Key Consideration: This method is effective but can be slow and requires some physical effort.
2. Chain Override:
   • Common For: Larger, heavier industrial and commercial roller shutters.
   • How it Works: A chain hangs down from the motor mechanism. Pulling the chain in one direction will raise the shutter, and in the other, it will lower it.
   • Key Consideration: Designed for heavier applications, this system is robust but still requires manual effort. Ensure the chain is free from obstructions before operating.
3. Uninterrupted Power Supply (UPS) / Battery Backup:
   • Common For: High-security applications, critical access points, or when frequent power cuts are an issue.
   • How it Works: An integrated battery system automatically takes over power supply to the motor when the mains electricity fails, allowing the shutter to operate normally for a limited number of cycles.
   • Key Consideration: Provides seamless operation during short power outages. The battery system will need regular maintenance and eventual replacement.

Step-by-Step Guide: Manual Operation During a Power Failure

Before attempting any manual operation, always prioritize safety.

1. Ensure Power is Off: If the power cut is localized or suspected, switch off the main power supply to the shutter at the fuse box to prevent accidental activation.
2. Locate the Override: Find the designated manual override point on your roller shutter motor or control panel. Consult your shutter's manual if you're unsure.
3. Engage the Override: Follow the specific instructions for your shutter type (e.g., insert and turn the crank, pull the chain). Some systems may require disengaging a clutch first.
4. Operate Slowly and Carefully: Do not force the mechanism. Apply steady, even pressure. If you encounter significant resistance, stop immediately.
5. Secure the Shutter: Once the shutter is in the desired position (fully open or fully closed), ensure it is securely locked or engaged to prevent accidental movement.

My Roller Shutter is Not Working (Beyond a Power Cut)

If your electric roller shutter isn't responding and there's no power cut, the issue could be more complex. Here's an overview of
