We engaged with Adexon to complete the safety certification for the fire curtains installed as part of our new build hotel and H&S sign off regulations.

Their engineer, James, attended site very promptly after arranging the contract with Eileen at their head office. The service provided by both Eileen and James has been swift, professional, and very informative to ensure we meet the certification requirements.

A number of colleagues and I attended Adexon's CPD Webinar on Fire and Smoke Curtains.

We all found the CPD to be very informative and worthwhile. It was especially interesting to note the exact components of a fire curtain and how they interact with each other.

I would highly recommend this CPD to all interested parties.

The fire curtain design of Adexon Fire & Smoke Curtains is a brilliant piece of simple but effective engineering. Great job.

It addresses all the issues. So. if there is a requirement for a fire curtain, yours is at the top of my list.

I was impressed with the recent technology implemented by Adexon in the fire curtain system, where the wear and tear of the curtain system that may lead to the breach of compartmentation is no longer a nightmare.

Thanks for the wonderful presentation, and I will not hesitate to suggest Adexon products to clients if I get an opportunity in some projects.

Fire Curtain Regulations

The Construction Product Regulations (CPR) states that any product covered by a harmonised standard must legally be CE marked to that standard. BS EN 16034 was harmonised on 1st Nov 2019 and covers vertical fire curtains, making it a legal requirement to CE mark vertical fire curtains to this standard, from this date.

In October 2016, EN 16034:2014 was recited in the Official Journal of the European Union.

This meant CE marking of operable fabric curtains would be legally mandatory under the CPR from 1st Nov 2019 (after the 3-year coexistence period).

The simple answer is, “Yes”. For a Certification Body to offer certification that is UKAS accredited they have to submit it to UKAS for auditing and checking e.g. to ensure there are no conflicts of interest. This ultimately protects the consumer. For example, Adexon’s product certifications are from Applus+, who in turn are accredited by an accreditation body called ENAC, a European equivalent to UKAS.

They require scheduled maintenance and servicing, every 6 months as a minimum. They should be tested weekly by site facility management. We recommend servicing and maintaining more often than the minimum due to their critical role in fire-safety.

This is highly unlikely as they’re not often used in situations separating people from escape routes. However, if there were a situation, when there is a power failure, each fire system will stay open for 30-minutes courtesy of the battery backup – unless the fire alarm signals it to close sooner – allowing plenty of time for safe evacuation to avoid being trapped. The standard evacuation time in an emergency is 2½ minutes. This also allows time to get the power back on if required and possible (through the mains or with backup power).

If you are still in the building more than 30-minutes after the power has failed, the curtains will deploy meaning you could be trapped in the rare circumstance you are on the wrong side of a fire curtain after deployment. In this situation you would likely be able to lift the curtain up and escape, due to their lightweight design. This does depend on the overall width of the curtain (wider is heavier). There is an optional extra called an emergency retract button that retracts the curtain (opens it) before closing it again after 30 seconds. However, after the batteries have depleted (30-minutes after power failure) these would not work. If you are concerned these unlikely events could combine in your building, please speak to us about setting the curtains to deploy earlier than the 30-minutes after a power failure so as to conserve some of the batteries for emergency retract button use

Yes, they can be used in a home setting, or anywhere that people reside overnight, for example, in residential schools, residential homes for the elderly, camp houses etc.

Due to their design, they can be used in spaces where a fire door could not be fitted e.g. due to size.

They can also separate areas designed to be open, for example, between floors, or to cover features such as stairs or lifts, which also applies to the open-plan homes.

Despite having names that are remarkably similar, fire retardant curtains and fire curtains have very different applications, safety benefits, and costs, and therefore should not be confused.

Fire retardant curtains are window dressings used to keep out the light, that have a coating applied to the fabric which allows them to withstand ignition for a period of time.

Automatic fire curtains are specialist active fire protection measures that, once deployed, provide compartmentation for the building and help to limit and stop the spread of fire.

The simple answer is – yes.

For a Certification Body to offer certification that’s UKAS Accredited they have to submit it to UKAS for auditing and checking e.g. to ensure there are no conflicts of interest.

Adexon’s product certifications are from Applus+, who in turn are accredited by ENAC, a European equivalent to UKAS.

Yes! We realise it sounds odd, but active fire curtains are a form of passive fire protection – they don’t suppress the fire, they merely compartment and stop spread like walls, fire rated glazing, fire doors etc.

The word ‘active’ describes them in contrast to static fire curtains. Active fire curtains are ‘invisible’ (out of sight) until needed and then deploy on fire alarm, to provide the passive fire barrier required. Static fire curtains are permanently in place e.g. in loft spaces where no access is required.

Fire curtains are powered by an electric tubular motor, connected to a control panel. The motor unrolls the fabric of the fire curtain, allowing it to deploy.

The fabric unrolls, either horizontally or vertically, until the opening being protected is sealed by the bottom bar of the glass fibre fabric reaching and creating a seal with the floor.

For a horizontal curtain, instead of a ‘bottom bar’, the curtain has a ‘leading-edge bar’ that travels to the other end of the opening, creating a seal, or it meets the leading-edge bar of the curtain that is travelling from the other side, if it is a bi-parting fire curtain.

This deployment is crucial for the prevention of flame and/or smoke spread, as it separates and compartmentalises the space. This allows the creation of a protected escape route and keeps the fire from the next space.

They’re connected to the alarm system, which when sounded, triggers the deployment.

This deployment speed is carefully calibrated so as not to be too fast and cause injury for people passing underneath it, or too slow and become ineffective, with a descent speed of between 0.03 – 0.3 mps (metres per second).

If the curtain is in the Vertical or Concertina orientation, then it will have a gravity fail-safe to ensure deployment in the event of power failure.

Horizontal curtains have a secondary power source, such as rechargeable batteries to ensure that the curtain can still move across the space if the primary power source fails.

We recommend that all fire curtains have smoke control as standard. It is not always requested by the fire strategy but we all know ‘there is no smoke without a fire’.

We can help design the installation so as little of the curtain as possible is visible once installed in the space.

Fire curtains can be installed so they sit flush with ceilings and edges, so it is visible only once deployed.

Yes, it is essential that all fire curtain systems have battery-back up to ensure they continue to function if they lose mains power.

Horizontal fire curtains, due to the direction of closure, require a secondary power source to ensure deployment. This secondary power source is a rechargeable, 30-minute, battery backup, so you have peace of mind that no matter what the situation, your space will be protected. This curtain cannot utilise a gravitational fail-safe due to the direction of closure.

Vertical and concertina fire curtains also have a battery back-up which means they will stay in their ‘open’ position for 30 minutes after loss of mains power e.g. in a fire situation. This is to allow safe evacuation prior to the fire alarm signalling them to close (deploy). They also have gravitational fail-safe to ensure deployment after the 30-minute battery back-up is depleted.

With a concertina fire curtain, these come fire tested but without smoke (, or just smoke tested, ( (to EN 12101-1)

The reason you cannot have smoke on a concertina fire curtain is due to the EXAP for the associated smoke test, BS EN 1634-3, prohibiting the use of overlapping fabrics. This is because the smoke test on fire doors (which the concertina fire curtain and all fire curtains are tested as) is a test of leakage around the perimeter and obviously overlapping fabric would have a significant impact on that (voids the measurement). The leakage allowed is 3m3/ linear meter of perimeter (excluding the threshold)/ hour at the pressure differential.

EXAPs are the test method for products bigger than the furnace, which just about all concertinas are. Concertina fire curtains are made from a series of overlapping fabrics, and this makes them outside the scope of BS EN 15269-20:2020.

BS EN 15269-20 is the EXAP for BS EN 1634-3:

You can have a dedicated concertina smoke curtain tested to EN 12101-1 as this is a separate test series to the fire products and the scope doesn’t limit the use of overlapping fabrics as it is a permeability test as opposed to a perimeter leakage test.
