Double Leaf Smoke Vents

AWAK double-leaf smoke vent is designed for large roof openings with both leaves opening together to provide a large effective smoke exhaust area. This allows the required performance to be achieved with fewer roof penetrations, which can mean a simpler and faster installation. During normal operation the same opening brings natural daylight into the building and can also be used for everyday ventilation. It is particularly well suited to large warehouses, production facilities and distribution centres.

Product Characteristics

Fewer openings in the same roof

More exhaust area from a single point means a shorter installation and fewer joints to seal.

Two independent actuators

Each leaf has its own actuator, electric or pneumatic, controlled as part of the smoke control system.

Lower lighting costs

The same roof opening that helps remove smoke in a fire also brings natural daylight into the building all year round.

Smoke vent upstand

The upstand is made of galvanised steel sheet with a minimum thickness of 1,25 mm and consists of four sections. Its height can be adapted to the roof structure and project requirements, ranging from 300 to 1000 mm. Standard heights are 350, 500, and 750 mm. A supporting structure is required around the perimeter of the upstand.

Upstand configurations:

Cover

Multi-wall polycarbonate (PC) – available in thickness of 10, 16, 20 and 25 mm. The outer surface is protected by a UV-filter coating.
KERA Fire Protect Panels – fire-retardant panels with BROOF(t1) classification, available in thicknesses of 21, 27 and 33 mm.
Domes – single or multilayer versions, made of acrylic or solid polycarbonate.
Light transmission – clear or opal finishes are available. Opal covers are standard for KERA Fire Protect panels.
Solar Control – multi-wall polycarbonate with a special coating that helps control solar radiation and reduce excessive heat gain during summer.

Actuators

Two types of actuators are available for opening the smoke vent:

Electric – 24 V DC actuator with a current consumption of 2.0 - 8.0 A.
Pneumatic – one- or two-way actuators powered by CO₂ cartridges.

Double-leaf versions require two actuators, one for each leaf.

Selected configurations can also provide daily natural ventilation.

Smoke deflector

An optional component made of galvanised steel sheet, designed to improve the aerodynamic performance of the smoke vent and increase its effective smoke extraction area.

Directional nozzle

An optional sheet-metal component designed to improve smoke flow and support effective smoke extraction.

Smoke extraction performance

The declared performance classes are specified in the Declaration of Performance (DoP), under CE marking reference 1488-CPR-0042/W, in accordance with EN 12101-2:2003.

Re 1000 – reliable operation during 1,000 opening and closing cycles, with the smoke vent reaching the fire position each time. This means 1000 times activation of the trigger system without loss of efficiency.
SL 250 / SL 550 / SL 650 / SL 900 – reliable operation under loads of 250, 550, 650 or 900 N/m² respectively, with an opening time of less than 60 seconds.
T (00) – products in this class are suitable for installation in buildings where the ambient temperature is above 0 °C.
WL 1500 – resistance to wind load of 1,500 Pa, with an opening time of less than 60 seconds.
B 300 / B 600 – classification for operation at temperatures of 300 °C and 600 °C, respectively.

Additional options

Ventilation – a dual function system can be fitted to the smoke vents to provide natural ventilation during everyday operation. For electrically operated smoke vents, the same 24 V DC actuator can operate both the smoke exhaust and ventilation functions. For pneumatically operated versions, daily ventilation can be provided by an additional 230 V AC electric actuator or a bidirectional pneumatic actuator. As standard, for double-leaf smoke vents, one actuator is used for the ventilation function, opening one leaf.
Anti-drop grille – an optional safety feature designed to help prevent falls through the roof opening.
Upstand colour – the inner surface of the upstand can be painted in a selected RAL colour. Standard colours are: RAL 9010, RAL 9002 and RAL 9003.
Smoke control system integration – the smoke vent can be integrated with a smoke control and ventilation system, including a control unit (e.g. Actulux or AFG), smoke detectors and manual alarm buttons.
