Standards and guidelines

DIN 4102-6, standard fire resistance test
EN 1751 Ventilation for buildings – Air terminal devices

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

Construction with fusible link

Functional description

Fire dampers for self supporting F30 suspended ceilings shut automatically in the event of a fire and prevent the propagation of fire and smoke through ductwork to adjacent designated fire compartments. In the event of a fire, the damper is triggered at 72 °C or at 95 °C (use in warm air ventilation systems) by a fusible link inside the damper. The release mechanism is accessible and can be tested from the outside (i.e. from the room).

Construction with spring return actuator

Functional description

The spring return actuator enables the motorised opening and closing of the damper blade; it can be activated by the central BMS.

In the event of a fire, the damper is triggered thermoelectrically at 72 °C or 95 °C (use in warm air ventilation systems).

As long as power is supplied to the actuator, the damper blade remains open.

If the supply voltage fails, the damper closes (power off to close).

Motorised fire dampers can be used to shut off ducts.

The torque of each actuator is sufficient to open and close the damper blade even while the fan is running.

The spring return actuator is fitted with limit switches that can be used for capturing the damper blade position.

Nominal sizes – fire damper	300, 400, 500, 600, 625 mm
Nominal sizes – spigot	160, 200, 250, 315 mm
Differential pressure range	Depends on the spigot and diffuser
Operating temperature	At least 0 – 50 °C **
Release temperature	72 °C or 95 °C (for warm air ventilation systems)
Upstream velocity	Depends on the spigot and diffuser, usually about 3 – 5 m/s

** Temperatures may differ for units with attachments

Square fire damper for the isolation of ducts in self supporting fire-resistant suspended ceilings. Satisfies high ventilation requirements when combined with a non-combustible ceiling diffuser or swirl diffuser. Suitable for supply and extract air

Ready-for-operation unit, which includes a fire-resistant damper blade and a release mechanism. Fire resistance class: K30-U

For installation in self supporting F30 fire-resistant suspended ceilings: tile ceilings (screw-fixed or primed), metal ceilings, and gypsum friezes of metal ceilings.

Thermal or thermoelectric release at 72 °C or 95 °C (warm air ventilation systems).

Constructions with spring return actuator for opening and closing the fire damper independent of the nominal size and even while the ventilation system is running, e.g. for a functional test.
