Smoke compartments are formed to prevent smoke spreading throughout a building. Our draft curtains are impermeable to smoke-leakage, within set criteria and offer a level of resistance to heat. Automatic Draft curtains are also used for smoke channeling. It is often desirable to direct smoke into certain zones for extraction. This is formed using small, rapid drop and often zone controlled banks of curtains. The major requirement for this type of curtain is fast deployment, minimum deflection and high degree of tolerance to hot smoke.

The DSI-D1HR Automatic Smoke Curtain System is totally gravity fail safe, resets automatically, and incorporates the latest in electronic technology. As a result, it is one of the most advanced, yet cost effective systems on the market.

The DSI Automatic Draft Curtain Model DSI-D1HRS single barrel configuration for widths under 16ft and Model DSI-D1HRM multi barrel configurations for widths over 16ft create a one hour opening protective smoke and fire barrier.

There are also buildings and departments stores that have open atria designs spanning many floors and to prevent the spread of smoke and fire from one floor to another and to facilitate the rapid extraction of smoke, many of these buildings use a roof level access system complemented by an inlet make up air facility and the deployment of Automatic Draft Curtains around the perimeter edge. Sophisticated control systems allow for the draft curtains to facilitate these strategies by employing staged and separate deployments, level by level or even curtain by curtain, with multiple alarm inputs being reacted to.

DSI Static Draft Curtains are an effective product designed to provide protection against smoke in commercial and industrial structures. Secured to structured steel, draft curtains ensure the smoke and hot gases arising from fire to remain buoyant within the smoke zone consistent to the smoke management strategies.

Used in both sprinklered and non-sprinklered buildings for automatic smoke removal. While there are various warehouse fortification options, draft curtains provide an affordable yet highly effective solution for improving fire and smoke control.

Conventional doors only account for about one and a half percent of construction dollars. But they are responsible for a full 20 percent of owner problems. This is because conventional doors contain parts from as many as 15 different manufacturers. Each part is sourced separately, then put together in the field. The Syntégra™ Door system offers a better way.

We custom-tailor a complete door system for each opening. Each system uses components designed to work together and assembled by experts in our factory. The result? Fewer moving parts, lower maintenance costs, unparalleled reliability and longer life. And because each door arrives at the job site assembled and ready to install, construction is faster and more cost-effective.

Once installed, the Syntégra™ Door System is guaranteed to perform flawlessly through millions of cycles. They have been proving themselves in some of the most demanding and diverse applications imaginable. And should a Syntégra™ Door System ever need service, it will be handled by our factory-trained installers here at Door Systems.

All Temperature rise doors exceed the fire code limits by using special construction that allows us to achieve a 450 degree for 30 minutes maximum temperature rise rating on our Syntégra™ Door System.

As with all our doors, the Stairwell Temperature Rise door has the lowest smoke leakage rating in the industry, comes in a variety of low profile hardware, and installs in a matter of minutes.

Temperature Rise Doors come with either 90-minute or 180-minute positive pressure fire labels. Built-in electronic locking functions for security purposes are optional as well.

DSI-C3HR Fire Protective Smoke Curtains are totally gravity fail safe and incorporate the latest in electronic technology. As a result DSI-C3HR UL 10D Smoke Curtain is one of the most advanced, yet cost effective systems on the market.

The DSI Smoke and Fire Curtain Model DSI-C3HRSS single barrel configuration for widths under 16ft and Model DSI-C3HRSM multi barrel configurations for widths over 16ft create a three hour opening protective smoke and fire barrier.

The assembly comprises a fire rated fiberglass fabric wound around a roller which encases a compact head box that is typically installed above the ceiling with side guides that are buried in the wall. This makes the system virtually invisible until activated.

Limit switch control has been replaced with current-limiting systems to determine the upper position of the curtain. The 24v motor will retract the curtain until the bottom bar pulls against the underside of the head box. The current drawn by the motor will begin to rise, this will be detected by the motor control circuit and the supply will be stepped back to a holding voltage of approximately 4 volts.

Upon receipt of a fire or test signal the holding voltage will be removed to the motor. The weight of the bottom bar will force the motor windings to return generating a back EMF. This facility ensures a controlled descent of the curtain even in the event of total power failure.

This method of operation should be used to deploy the system at all times. A curtain that is powered down under normal test conditions from either mains power or the battery supply is only proving that it can deploy when powered. This does not confirm the ability to fail safe.
