Standards and guidelines
- Construction Products Regulation
- EN 15650 Ventilation for buildings – Fire dampers
- EN 1366-2 Fire resistance tests for service installations – Fire dampers
- EN 13501 Fire classification of construction products and building elements
- EN 1751 Ventilation for buildings – Air terminal devices
Supply package
If attachments and accessories are factory set with the fire dampers, they are already included in the order code. Installation situations may require supplementary materials for assembly and fixing, such as mortar, screws, mineral wool, etc., to ensure correct installation. Such materials are not included in the scope of delivery, unless they are expressly described as part of the delivery. The selection of supplementary attachments or accessories as well as the determination and provision of materials for assembly and fixing is the responsibility of the parties involved in the construction
and must be carried out taking into account the desired classification.
Maintenance
- The functional reliability of the fire damper must be tested at least every six months; this has to be arranged by the owner of the ventilation system; functional tests must be carried out in compliance with the basic maintenance principles stated in EN 13306 and DIN 31051. If two consecutive tests, one 6 months after the other, are successful, the next test can be conducted one year later. If 2 consecutive tests, one 6 months after the other, are successful, the next test can be conducted one year later
- A functional test involves closing the damper blade and opening it again; with a spring return actuator this can be done via remote control
- Fire dampers must be included in the regular cleaning schedule for the ventilation system
- For details on functional tests, maintenance and inspection refer to the installation and operating manual
Technical data
- Nominal sizes: 200 × 100 to 1500 × 800 mm
- Casing lengths: 305 and 500 mm
- Volume flow rate range: up to 14400 l/s / up to 51840 m³/h
- Differential pressure: up to 2000 Pa

Incorrect use:
- as a smoke control damper
- outdoors without sufficient protection against the effects of weather
- in atmospheres where chemical reactions, whether planned or unplanned, may cause damage to the fire damper or lead to corrosion
