What is an ES fire damper?
Actionair – Actionair ES Rated Automatic Fire Damper CE Marked ‘ES’ Rated Fire dampers used to prevent spread of fire and smoke maintaining compartmentation.
Can smoke dampers and fire dampers be combined?
Upon detection of smoke, the actuator will automatically close the damper components. A combination fire/smoke damper will close upon detection of EITHER fire or smoke. This means that they can be interlocked with the building fire alarm system such that they close after receiving a signal from the fire alarm system.
How does a combination fire smoke damper work?
Fire dampers respond to heat, when the temperature reaches a set point the damper slams shut. Smoke dampers respond to the detection of smoke, and close automatically. They resist the passage of smoke, toxic gases and air through a fire barrier.
Do you need a fire damper in a 30 minute fire wall?
Where a duct passes through a fire hazard room, but does not serve it, fire dampers are not required but the duct must have fire resistance of 30 minutes in respect to integrity and insulation.
Where are fire smoke dampers required?
Generally, fire dampers are required where air ducts penetrate walls that are rated for 2-hours or more. They are needed in all air transfer openings (non-ducted) in rated walls, regardless of the rating. And they are required at some, but not all penetrations of rated floor assemblies and shaft enclosures.
How many types of fire dampers are there?
There are two types of fire damper closing system: those with a fuse mechanism and those with an actuator, which is motorised, and to which you can connect a smoke detection system.
What NFPA 105?
NFPA 105, Standard for Smoke Door Assemblies and Other Opening Protectives, offers designers, engineers, installers, and contractors the most comprehensive requirements for the performance of required smoke door assemblies, smoke dampers, and other opening protectives that are intended to limit the spread of smoke.
How do you test a fire smoke damper?
The essential test is that the damper will open and close and no obstructions are present. NFPA 729 is referenced when any smoke detection is present. The operation must be under the airflow conditions that the system will encounter.
Is fire damper testing statutory?
Under the Regulatory Reform (Fire Safety) Order it is a legal requirement to test fire dampers at regular intervals in accordance with fire safety in the design, management and use of buildings code of practice (BS:9999 2017), using a method known as ‘drop testing’.
What is the torque of BELIMO fire damper actuators?
Belimo fire and smoke damper actuators are designed for operation in smoke and combination fire and smoke dampers in ventilation and air-conditioning systems with a torque range from 18 in-lbs to 180 in-lbs @ 350°F.
What classifications do smoke control dampers have?
Smoke control dampers; and classified to BS EN 13501-4:2016 Fire classification of construction products and building elements. Smoke control dampers for ducts are categorised as single-compartment smoke control dampers for use in single-compartment areas, and multi-compartment smoke control dampers for use in multi-compartment areas.
Are smoke dampers required for ducted ventilation services?
So, where ducted ventilation services could compromise the integrity of that compartmentation, fire dampers and smoke dampers can provide a controllable solution. The principal testing standard is BS EN 1366 Fire resistance tests for service installations.
What is the failsafe position for smoke control dampers?
There is no particular failsafe position for smoke dampers. Smoke control dampers (including fire-resisting types as discussed below) should be CE marked to BS EN 12101-8:2011 Smoke and heat control systems. Smoke control dampers; tested to BS EN 1366-10 Fire resistance tests for service installations.
