Rotating Beacon: Halogen or LED, 24V DC or 230V AC

A forklift comes through the roller door at the end of the shed, and nobody walking the other way gets any warning. A rotating beacon over the door fixes that, but the order form still wants a lamp type, a supply voltage, an IP rating and a mounting style. The sections below take those choices one at a time, for fixed installs on a factory floor, site gate, roller door or machine.

Rotating or Flashing

A rotating beacon sweeps a beam around the area, so the light travels across the floor and walls and is seen from several sides. The Clipsal mirror model in the range uses a rotating mirror for 360° visibility, with a listed speed of 120 RPM. A flashing or strobe lamp is a sharper on and off pulse.

For a gate or door where people approach from different directions, a sweeping beam is a common choice. If a flash is enough, the strobe beacons range also lists flashing and strobe lamps, and the flashing beacon LED options are covered separately.

Halogen, Mirror or LED

The range covers three builds. Allen-Bradley halogen beacons come in 60mm, 120mm and 160mm sizes at 24V AC/DC, such as the 120mm blue halogen beacon. Mirror beacons like the Clipsal rotating mirror beacon put a high-brightness LED in front of a rotating mirror. Multi-LED beacons, such as the Moflash 18 LED units, list 80 to 120 RPM.

The LED listings show a low draw, and the Clipsal listing mentions long LED life, so there should be fewer lamp changes on a beacon nobody wants to climb to. For a like-for-like swap on a site that already runs halogen units, check the voltage and size before assuming an LED unit will fit.

24V DC or 230V AC Supply

Settle the supply first. A 24V beacon can run from a machine's control supply or another low-voltage source, which keeps the signalling on extra-low voltage. Mains beacons, listed as 230V AC on the Moflash and 240V AC on the Tesla, need the same protection and isolation as any other mains circuit.

The 230V AC wall or surface beacon from Moflash is rated 60 W with an E14 lamp holder and a listed 0.29A draw. Where the supply is not certain, the 85-280V AC/DC LED rotating beacon lists 0.06A across that range, which can save a re-order if the supply is not what the drawing said.

Check the nameplate before connecting. A 24V beacon on mains is likely to be damaged, and a mains beacon on 24V will not run properly.

Wiring 12V and 24V DC Beacons

Low-voltage DC beacons are more sensitive to cable length than mains units, because the same voltage drop is a bigger share of a small supply. For a long run to a gate or the far end of a shed, work out the cable size for 12V runs before you pull cable, and use the same approach for 24V.

The range includes 12V DC and 12 to 24V DC units, such as the 115mm IP66 heavy-duty warning light. A wide input like that gives some room if the supply is not yet fixed, but check the listed current draw before sizing the cable.

IP Rating and Mounting

Several beacons in the range are listed at IP65. That generally means dust-tight and protected against water jets, which is a better starting point for an exposed gate than IP54, where the protection is generally against dust ingress and splashing. The IP54 orange LED rotating beacon from Clipsal sits at the lower end, and the 70mm IP67 LED rotating beacon from Allen-Bradley goes higher.

The Moflash 230V and LED models are surface mount, and the Clipsal mirror beacon lists surface or pole mounting. Check the base dimensions against the bracket or wall box you plan to use, and confirm the surface can carry the listed weight, which runs from 1.0 kg to 1.5 kg on the Moflash and Clipsal units. The Clipsal listing also gives an operating range of -30°C to +50°C, which is worth checking for a cold room or an exposed site.

Adding a Siren or Sounder

A beacon on its own is silent. At a gate or door where someone may have their back to the light, a sound with the beacon usually gets attention faster. If you want both on one circuit, sounder beacon selection covers the sound, light, voltage and IP rating choices.

When a Rotating Beacon Is Not the Right Tool

If the real job is showing machine status rather than warning an area, choosing a stack light with colour segments tells the operator more. A rotating beacon says something is happening, not what.

If the only job is showing that a circuit is live, a rotating beacon is more than the job needs.

Common Mistakes When Ordering a Rotating Beacon

• Ordering before checking the supply. A 24V beacon and a 230V beacon can look the same in the catalogue, and the wrong one on the wrong supply can be damaged or will not run properly. Write the supply voltage on the order before choosing the model.
• Ignoring the lamp holder. The Moflash 230V beacon lists an E14 lamp holder and 60 W, so a spare lamp has to match both. Note the lamp details at install, not at the first failure.
• Trusting the IP rating at the cable entry. An IP65 beacon only stays IP65 if the cable entry is sealed too. An unsealed entry lets water in, and the rating on the box no longer means much.
• Choosing the lens colour last. The listings come in amber, blue, red, orange and clear, so the model that fits the supply may not come in the colour the site uses. Check supply, size and colour together.

Frequently Asked Questions

Choosing a Rotating Beacon

Should I use a rotating beacon or a strobe at a roller door?

A rotating beacon sweeps a beam around the area, and a strobe gives a sharp flash. Both are in the range, so pick on how people approach the door and how much light is already in the shed.

Is an LED rotating beacon better than a halogen one?

LED units list a lower current draw, and the Clipsal listing mentions long LED life, so there are fewer lamp changes. Halogen units are still in the range, and for a like-for-like replacement the voltage and size matter more than the lamp type.

Which rotating beacon works from a 12V DC supply?

Pick a unit listed for 12V DC, such as the 125mm 12V DC red LED revolving light, or a 12 to 24V DC model. A 24V-only unit may not run properly on 12V.

Wiring and Supply

What cable size do I need for a 24V DC rotating beacon?

It depends on the beacon's current and the length of the run. Take the listed current, add a sounder if one shares the circuit, and check it against the twin core cable amp rating before choosing the cable.

Can a sounder share the same 24V supply as the beacon?

It can if the supply covers both loads and both are listed for the same voltage. Add the currents together first, and see warning sounder selection for output, tones and voltage.

Compliance and Outdoor Use

Does a rotating beacon need a licensed electrician?

Wiring to a 230V supply is generally licensed electrical work in Australia. The Clipsal listing states that installation by a licensed electrician is required, and the Moflash listings recommend professional installation. Rules for extra-low voltage work can differ by state, so check with your regulator.

Can a rotating beacon be mounted outdoors?

Check the IP rating on the listing. IP65 generally means dust-tight and protected against water jets, but the base and cable entry still need to be sealed properly.
