The Domus TRAK 3-Circuit Adaptor is the connector between a light andthe track 709040mm,240V, in black or white.

The small part that makes the three circuits real

• A 3-circuit track carries three live conductors. The adaptor is whatselects which one a given head connects to.
• SO THE ADAPTOR IS WHERE THE SYSTEM’S WHOLE POINT IS DELIVERED. The trackprovides the capability; the adaptor assigns it; the switchboard makes it usable. Get any of the three wrong and the other two are wasted.
• SETTING IT IS DONE AT INSTALLATION and rarely revisited which iswhy circuit assignment is worth writing down. A shop that cannot remember which headsare on which circuit ends up switching all three together, which is exactly the outcome the system wasbought to avoid.
• RECORD IT ON A CEILING PLAN AND LEAVE IT WITH THE BUILDING ittakes five minutes at handover and saves a survey later.

It is also what lets a non-track fitting go on track

An adaptor is the standard interface between the track and whatever hangs from it. THAT MEANS PENDANTS AND OTHER FITTINGS CAN BE PUT ON TRACK, not only purpose-made trackheads which is a genuinely useful thing in a retail or hospitality fitout wherethe pendant over a table may need to move when the table does. Confirm the fitting’sweight and its fixing arrangement with us first; the adaptor’s own load limit is notpublished.

Its datasheet belongs to something else

• The sheet attached to this listing is flagged contradicted, and its item listnames four other products. It publishes a voltage and an IP rating that describe thetrack system generally rather than this adaptor.
• THE RECORD’S OWN FIGURES ARE WHAT WE HAVE PUBLISHED 709040mm, 220240V AC, 3-year warranty and those arecorroborated by the title and by the family description.
• WHAT IS NOT PUBLISHED ANYWHERE IS THE ADAPTOR’S CURRENT AND WEIGHT LIMIT. On a component that carries a fitting from a ceiling and passes its full load, those are thespecifications that matter. Ask us before hanging anything heavier than a standard trackhead.

70 90 40 mm small, and visible

The adaptor sits between the track and the fitting, so it is seen on every head in therun. MATCH IT TO THE TRACK, NOT TO THE FITTING. A black adaptor onwhite track is a row of dark blocks along a white line, and it draws the eye to the hardware rather than thelight. Where the track, adaptor and head all match, the run reads as one continuous pieceof equipment. On an exposed-services ceiling, black throughout usually disappears best;against plastered white, white does.

Count them against the head count, not the run

One adaptor per fitting. THAT IS OBVIOUS AND STILL THE COMMONEST OMISSIONON A TRACK ORDER because the track is ordered by length and the heads byquantity, and the adaptor belongs to neither list. Some heads ship with an adaptorincluded and some do not. Tell us which heads you are using and we will say how manyadaptors the order needs.

A system of parts, and the ones people forget

A track run is a system rather than a product. Tell us the run length, thehead count and the mounting and we will list everything it needs in one go.

What is published

Where it works

• Every fitting on a 3-circuit track one each.
• Putting pendants on track movable feature lighting.
• Where the circuit split is the reason for the system.
• Not forgotten from the order it belongs to no other list.
• Not with a heavy fitting without confirming the limit.

Specifying it

3-circuit track adaptor. 70 90 40mm, 220240V AC. Black or white. 3-yearwarranty. THIS IS THE SMALL PART THAT MAKES THE THREE CIRCUITS REAL. The track provides the capability,the adaptor assigns it, and the switchboard makes it usable get any of the three wrong and the other twoare wasted. SETTING IT IS DONE AT INSTALLATION AND RARELY REVISITED, so record the circuit assignment ona ceiling plan and leave it with the building: a shop that cannot remember which heads are on which circuitends up switching all three together, which is exactly what the system was bought to avoid. ONE PERFITTING, and it is the commonest omission on a track order because it belongs to neither the length listnor the head list.

Questions

What does the adaptor do?

It selects which of the three live conductors a given head connects to. A 3-circuit track carries three; the adaptor assigns the head to one. So the track provides the capability, the adaptor assigns it, and the switchboard makes it usable get any of the three wrong and the other two are wasted.

Is the setting permanent?

Practically, yes it is done at installation and rarely revisited. Which is why circuit assignment is worth writing down: a shop that cannot remember which heads are on which circuit ends up switching all three together, exactly the outcome the system was bought to avoid. Record it on a ceiling plan and leave it with the building; it takes five minutes at handover and saves a survey later.

Can I put a pendant on track?

Yes an adaptor is the standard interface between the track and whatever hangs from it, so it is not limited to purpose-made track heads. That is genuinely useful in a retail or hospitality fitout where the pendant over a table may need to move when the table does. Confirm the fitting’s weight and fixing arrangement with us first; the adaptor’s own load limit is not published.

How many do I need?

One per fitting obvious, and still the commonest omission on a track order, because the track is ordered by length and the heads by quantity and the adaptor belongs to neither list. Some heads ship with an adaptor included and some do not. Tell us which heads you are using and we will say how many the order needs.

Black or white?

Match it to the track, not to the fitting. The adaptor sits between the two and is seen on every head in the run a black adaptor on white track is a row of dark blocks along a white line, and it draws the eye to the hardware rather than the light. Where track, adaptor and head all match, the run reads as one continuous piece of equipment.

Are its published figures reliable?

The record’s are. The attached datasheet is flagged contradicted and its item list names four other products, describing the track system generally rather than this adaptor. We have published the record’s own figures 70 x 90 x 40mm, 220240V, 3-year warranty which the title and family description corroborate.

What else does a track run need?

More than most people order. Track by length, heads by quantity, one adaptor per head, a feed or live end per run, a connector per join, an end cap per run end, and suspension every 1.5 to 2 metres if it is not fixed directly. A track run is a system rather than a product. Tell us the run length, head count and mounting and we will list everything in one go.
