Gate motors run on electricity. Without a backup battery, the gate stops the moment the power goes. Prepare these four things in advance.

1. Backup battery

Many motors can take a backup battery. When the power fails, the motor switches to the battery automatically and can open and close a number of times. How many depends on the gate weight and the battery size.

• Ask your installer whether your motor already has a backup battery
• Batteries wear out; most should be replaced every 2 to 3 years
• Test once a year by switching off the power and opening and closing the gate

2. Release key

Every motor has a key or lever that disengages it so the gate can be moved by hand. Keep it somewhere everyone knows and can reach, not in a car parked behind the gate.

3. Opening by hand, safely

• Make sure the power is really off, or switch off the motor's breaker first
• Unlock and pull the release lever as shown in the manual for your model
• Move the gate slowly; do not shove it or let it run on its own
• When power returns, re-engage the motor so automatic operation works again

At handover, ask the technician to show everyone in the house how to do this once.

4. Other options

• Solar panel: charges the motor battery during the day; useful where power cuts are frequent or the gate is far from the house
• Pedestrian gate: if you have one, keep its key handy
• UPS or generator: for larger buildings where the gate must always work

Safety

• Keep the release key and remotes away from children
• After operating by hand, test the safety sensors again
• If the gate is very hard to push, the track or wheels may need attention; ask a technician
