A fire curtain is a fabric barrier stored in a ceiling or wall box that drops automatically when a fire is detected. It closes an opening, such as an atrium edge or lift lobby, to resist fire spread. In UAE buildings, curtains let designers keep open layouts while still dividing the building into fire compartments. Smoke control needs separate testing, and curtains must be approved like any fire barrier.

Fire curtains are often confused with smoke curtains, which do a different job. This guide explains how each type works and where each suits UAE buildings best. It covers the main standards, including BS 8524, EN 1634-1 and UL 10D. It also explains how curtains are tested and maintained after installation.

What is a fire curtain?

A fire curtain is an active barrier made from fire-resistant fabric, usually woven glass fibre with a protective coating. It stays rolled inside a steel box until the fire alarm sends a signal. The curtain then descends to close the opening it protects, forming a fire barrier.

Most fire curtains descend by gravity under controlled speed, so they still deploy if power fails. A motor and control panel raise the curtain again and manage the descent in normal conditions. Battery backup keeps the controls working during a mains power failure.

Quick Answer

A fire curtain is a fire-resistant fabric barrier rolled in a ceiling box until the fire alarm triggers it. It normally descends by gravity, so it deploys during power failures.

What is the difference between a fire curtain and a smoke curtain?

A fire curtain resists fire and heat for a rated time, while a smoke curtain mainly controls smoke movement. Fire curtains are tested for integrity, and sometimes radiation, under EN 1634-1. Smoke curtains are classified under EN 12101-1 by their exposure temperature and duration.

Smoke curtains often form fixed or deployable screens that channel smoke towards extract fans. EN 12101-1 uses D classes for 600°C exposure and DH classes for the standard fire curve. A single product can carry both kinds of rating if it has been tested for each.

Quick Answer

Fire curtains resist fire for a rated time under EN 1634-1, while smoke curtains control smoke under EN 12101-1. Some products are tested and then classified for both functions separately.

Where are fire curtains used in UAE buildings?

Fire curtains are used where a solid wall or door would spoil an open design or daily use. Typical locations include atrium edges, escalator openings, lift lobbies, open-plan retail frontages and hotel reception areas. They can also protect service counters and openings between compartments.

Curtains cannot simply block escape routes, because occupants must still be able to leave. A curtain crossing an exit path needs an approved means of escape, such as an integrated door. Atrium designs usually combine curtains with atrium smoke control, so both systems must work together.

Quick Answer

UAE buildings use fire curtains at atrium edges, escalator openings, lift lobbies and open retail frontages. Curtains crossing escape routes need approved escape arrangements that still work once it deploys.

Which standards apply to fire curtains in the UAE?

Fire curtains in the UAE are usually tested to European, British or American standards. BS 8524-1, updated in November 2025, specifies design, testing and classification of active fire curtain barrier assemblies. BS 8524-2 covers their application, installation and maintenance.

American products are commonly tested to UL 10D, with installation and maintenance following NFPA 80. Whatever the standard, the product and design must be accepted by local Civil Defence under the UAE Fire and Life Safety Code. Our guide to fire rated doors in Dubai explains how opening protectives are approved.

Quick Answer

UAE fire curtains usually follow BS 8524-1 and BS 8524-2, EN 1634-1 testing, or UL 10D with NFPA 80. Civil Defence must also accept both the product and the design.

How are fire curtains tested and maintained?

Fire curtains need regular functional tests confirming they descend fully and at the correct speed. Technicians check the fabric, guides, bottom bar, motor, brake, batteries and control panel. Any tear, jam or obstruction must be corrected before the curtain returns to service.

The manufacturer's instructions and the applicable standard set the testing frequency, commonly including an annual drop test. Tests should be coordinated with the fire alarm contractor, because the alarm signal starts each deployment. Keeping the area below each curtain clear is as important as the servicing work itself.

Quick Answer

Fire curtains need functional drop tests and inspection of fabric, guides, motors, brakes, batteries and controls. Follow the manufacturer's intervals, and keep the drop zone permanently clear of stored items.

Frequently Asked Questions

How long does a fire curtain resist fire?
Fire curtains are available with fire resistance ratings from about 20 minutes up to several hours. The required rating depends on the fire-rated wall or opening that the curtain replaces.
Can a fire curtain replace a fire door?
A fire curtain can replace a door or wall only where the approved design allows it. Civil Defence must accept that the curtain provides equivalent protection for that particular opening.
Do fire curtains work during a power cut?
Most fire curtains descend by gravity with a controlled speed, so they still deploy without mains power. Battery backup keeps the control panel, warning sounders and lights working during outages.
What triggers a fire curtain?
A signal from the building's fire alarm system usually triggers the curtain to descend. Some installations also use dedicated local smoke detectors or key-operated controls for routine testing and reset.
What is an EW rating on a fire curtain?
An EW rating means the curtain maintains integrity and limits radiated heat for the stated time. It is tested under EN 1634-1 and then classified under the EN 13501-2 standard.
Can people walk under a descending fire curtain?
Curtains descend slowly and many include audible warnings and safety edges to protect people underneath. Nobody should stand beneath a curtain, and the drop zone must stay clear during tests.
Are fire curtains suitable for lift lobbies?
Yes, lift lobby curtains are common because they protect lift openings without needing permanent lobby doors. The product must be tested for that specific application and accepted by Civil Defence.
What happens if something blocks the fire curtain?
An obstruction can stop the curtain closing fully, leaving a gap for fire and smoke. Keep furniture, displays, trolleys and stock well away from the drop zone at all times.
How often should a fire curtain be serviced?
Service frequency follows the manufacturer's instructions and the relevant standard, commonly at least once a year. Busy retail or hotel areas with heavy traffic may benefit from more frequent checks.
Can fire curtains be retrofitted into existing buildings?
Yes, fire curtains are often retrofitted because they need less floor space than new walls. The retrofit design still needs Civil Defence approval and enough ceiling space for each box.

Main Takeaways

A fire curtain is a fabric barrier that descends automatically, usually by gravity, when the building fire alarm operates. Fire curtains resist fire under EN 1634-1, while smoke curtains control smoke under EN 12101-1. BS 8524 and UL 10D are the main product standards used for UAE projects. Regular drop tests, fabric checks and clear drop zones keep curtains reliable.

Using fire curtains well

Fire curtains let UAE buildings keep open atria and lobbies without giving up fire compartmentation. They only work when they are specified correctly, approved by Civil Defence and kept clear. The right rating depends on the opening they replace and the wider design around them. Coordination with the fire alarm and smoke control systems is essential from design to handover.

If you are planning curtains or inheriting existing ones, confirm their test standard, fire rating, approval status and service history. Then arrange a full functional drop test with the fire alarm contractor present to trigger it. QSERV maintains fire protection systems and opening protectives for commercial buildings across the UAE.
