Automatic Gates in Storm Season: Power Outages, Lightning and Flooding on the Gold Coast

From November through to March the Gold Coast gets its share of afternoon storms, and with them come the blackouts, lightning strikes and flash flooding that test every piece of outdoor electrical equipment on a property. An automatic gate is one of the most exposed. It sits at the lowest point of the driveway, it is wired to the house, and it is the thing you need to work when you are trying to get home in the rain. Here is how to get a Gold Coast gate through storm season without being locked in or out.

Power outages: the battery is everything

The first thing a storm takes out is the power, and a gate with no backup battery is a fixed fence until it comes back. Every gate motor we install has a backup battery, but a battery is a consumable. It loses capacity over a few years, faster in Queensland heat, and a battery that has quietly died will not announce itself until the lights go out.

Before storm season, have the battery tested under load, not just checked for voltage. If it is more than a few years old, replacing it is cheap insurance. On solar-powered gates the battery is the whole system, and its condition matters even more.

Know how many cycles your backup gives you. A healthy battery will typically open and close the gate a handful of times during an outage, which is enough for a family to come and go for an evening. It is not designed to run the gate for days. If outages in your area tend to run long, particularly on the hinterland side around Tamborine and the rural blocks, talk to us about a larger battery or a solar top-up.

The manual release: find it before you need it

Every automatic gate has a manual release that disengages the motor so the gate can be pushed open by hand. It is usually a key-operated lever on the motor housing. The number of people who discover they do not know where theirs is, or where the key went, during a blackout at ten at night in the rain is remarkable.

Find it now. Try it. Make sure every driver in the house knows how it works and where the key lives, and keep a spare key somewhere reachable from the street side of the gate, because the point of the release is to get in when you are outside. On a sliding gate, check the gate can actually be pushed by hand once released; a heavy gate on a track that has not been cleaned will not move easily.

Lightning and surges

A gate motor is an electronic control board at the end of a long cable, which is close to a description of a lightning target. A direct strike is rare. Surges through the mains during a storm, and induced surges from a nearby strike travelling down the cable to the gate, are not, and they are a common cause of a dead control board the morning after a big storm.

A surge protector on the gate circuit, at the switchboard or at the motor, reduces the risk considerably and costs a fraction of a control board. Photocells and intercoms on separate cable runs benefit from the same protection. If your gate was installed without surge protection, it is a worthwhile addition before the season starts.

Flooding and water

Gold Coast storms dump a lot of water quickly, and the gate sits where the driveway meets the street, which is often exactly where it runs. Above-ground motors are weather-resistant but not designed to be submerged, and a motor that sat in floodwater needs to be checked before it is powered up again. Underground swing gate motors are more vulnerable; their housings can fill with water and silt in a flash flood, and drainage of the pit is something to check every season.

If water has been over the motor, leave the gate on manual release and call for an inspection before switching the power back on. Powering up a wet control board is how a repairable problem becomes a replacement.

Wind and debris

Solid-panel gates catch the wind, and a storm gust loading a closed gate puts real stress on hinges, posts and the motor drive. Slatted and open designs shed wind better and are the usual recommendation on exposed sites. After a storm, check the gate for a bent rack, a shifted post or a hinge that has moved, and clear branches and debris from the track and the photocell line before running it. A gate that stops partway after a storm is very often just seeing a stick across the photocells.

Before the season: a checklist

Have the backup battery load-tested and replace it if it is old. Locate the manual release, try it, and put a spare key where you can reach it from outside. Fit surge protection if the gate does not have it. Check the drainage around an underground motor pit. Clean the track and the photocells. Make sure remotes have fresh batteries so you are not diagnosing two problems at once.

Most of that is covered in an automatic gate maintenance visit, and booking one in October or November puts it ahead of the storms rather than behind them.

After a storm: what to look at

If the gate is behaving oddly after a storm, check the obvious first: power at the breaker, debris in the track, photocells aligned and clean, and whether the battery has simply run flat after an outage and needs time to recharge. If the gate is dead with power restored, or behaves erratically, or has been under water, stop and call. Our mobile gate repairs and servicing across the Gold Coast, from Nerang and Robina to Helensvale and the Tamborine acreage, cover all the common brands, and storm damage is something we see every summer.

The short version

A gate that is ready for storm season has a battery you trust, a manual release you can find in the dark, surge protection on the circuit, and a clear track. That is an hour of preparation for a season of not being locked out.
