Fire & Smoke Actuators

Key Takeaways

2

Fire and smoke- Protecting people and tangible assets in case of a fire.

Goal: Create awareness that users can retrofit failed fire and smoke actuators without replacing

the entire damper assembly.

1. UL does not regulate replacements, the Authority Having Jurisdiction (AHJ) does.

2. Actuators must be replaced with one that is UL555 (fire) and/or UL555S (smokes) Listed.

3. Belimo offers training materials with the conformance test checklist for service technicians.

To a certain degree safety and quality are sides of the same coin.

C F&S dampers can be used for balancing – comfort and IAQ

E Our FS actuators consume low power

S Belimo provides safety by protecting life and tangible assets and

preventing financial harm in case of fire

I Direct couple mounting installation takes a fraction of the time of old linkage motors

M Belimo promotes adherence to code required testing and has retrofit instructions that help

maintenance

Toxicity ofSmoke

Smoke Control

NFPA reports that near 80% of deaths

in fires are due to smoke inhalation.

Toxicity of Smoke

Both fire & smoke are killers, but smoke

inhalation leads to unconsciousness & burns

Benefits of Smoke Control

10CESIM Talk 2019

Cools the fire compartment and delays the

flash-over by exhausting the hot gases

Supports the evacuation of people and

animals (smoke free escape routes)

Supports the rescue and fire fighting work

Protects asset values and the infrastructure

Damper Applications

CESIM Training - Americas 16

1. To maintain compartmentation, duct smoke detectors

will close dampers preventing the spread of smoke; 85%

containment.

2. As part of an engineered smoke control system,

dampers can be re-opened and controlled by the 15%

Fire Fighter Smoke Control System.

.

Applications

17CESIM Training - Americas

Compartmentation

Shafts – up to 50% of dampers

Regardless if HVAC fans are shutdown, without smoke

dampers, smoke will travel throughout the building via

both the supply and return damper shafts.

SMOKE WILL PASS OUT OF FIRE ZONE

INTO UNPROTECTED ZONES.

18CESIM Training - Americas

Containment Fire & Smoke Dampers

Barrier Walls

85% of installed fire & smoke dampers

are for containment.

Dampers in walls & ducts stop fire

and smoke.

COMPARTMENTATION IS INTACT.

19CESIM Training - Americas

Engineered Smoke Control Systems

Stairwells, underground buildings, exit corridors,

stages and auditoriums, elevator shafts, atria,

large spaces

15% of installed fire& smoke dampers are in

smoke control systems.
