Maintenance

Smoke control dampers must be operational at all times and must be maintained regularly so that they meet the performance requirements.

Maintenance is required at least every 6 months

A maintenance report must be created; documents must be kept for reference

The owner of the smoke extract system must arrange for a functional check of the smoke control damper every six months. This must be carried out taking the basic maintenance measures according to EN 13306 in conjunction with DIN 31051 into account. If 2 consecutive tests, one 6 months after the other, are successful, the next test on the fire damper can be conducted one year later.

Depending on where dampers are installed, country-specific regulations may apply.

For details on maintenance and inspection refer to the installation and operating manual.

Smoke control dampers are used in mechanical smoke extract systems. They are used for extracting smoke gases and for providing additional supply air to one or more fire compartments. The dampers are made of calcium silicate panels and are opened by an encased actuator; when smoke is detected, the actuator is triggered by a signal either from a duct smoke detector or from a fire alarm system. Smoke control dampers have two safe positions: open and closed.

In the case of fire-resistant smoke control dampers for multiple compartments, the safe position is either "open" or "closed", depending on the fire site and the path of the smoke to be extracted. If the safe position is 'open', the free area must be maintained even in the event of a fire. The blade of EK2-EU moves to the defined safe position upon receiving an automatically or manually triggered control signal. According to the specified time-temperature curve, the EK2-EU can still fully open or close after 25 minutes (MA, manual release). Type EK2-EU smoke control dampers are also approved for modulation applications (Cmod) – the damper blade can take any intermediate position, which allows for pneumatic balancing._{Regular maintenance of the smoke control damper is required to ensure its functional reliability.}

Installation type A, in a duct

Ducted on both sides, any airflow direction

Installation type B, additional supply air

The installation types A, B and C lead to differences in the pressure loss values and must be taken into account in the sizing.
Precise values based on project-specific data can be determined with our Easy Product Finder design program.
You will find the Easy Product Finder on our website

Sizing example:

Sizing for smoke extract (installation type "C") based on given volume flow rate and limited installation opening

Volume flow rate: q_v ≥ 15000 m³/h
Maximum height of the opening: H (installation opening) = 1.2 m
Inspection access panel, wall connectors and cover grille in RAL 9022 requested
Determination of nominal height (H) EK2-EU: Wall opening (H = 1200 mm) - casing thickness (100 mm) - perimeter gap (top 50 mm, bottom 50 mm) = 1000 mm

Rectangular or square smoke control dampers to product standard EN 12101-8, tested to EN 1366-10 and EN 1366-2, for use in smoke extract systems. Smoke control dampers not only prevent the spreading of smoke and combustion products between fire compartments, they also prevent the leakage of emitted, dangerous and poisonous fire suppression gases from the affected area, and they maintain positive pressure in pressure differential systems. The EK2-EU is suitable as a pressure relief damper for gas fire extinguishing systems. For extracting smoke gases and for providing additional supply air to one or more fire compartments. The EK2-EU can be used in smoke extract systems which have been approved for ventilation. The fire-resistant smoke control damper for multiple compartments is suitable for installation in solid walls and shafts, lightweight partition walls and ceiling slabs, as well as in and on fire-resistant smoke extract ducts. Open/Close actuator, with fully wired and ready-to-operate control module in a temperature resistant encasing as an option.
