Smoke removal and ventilation system

Smoke extraction systems divert smoke from the building so that escape and rescue routes remain usable and people can get out into the open. Passive smoke management does not require mechanical systems to support them. Instead, flexible fire and smoke curtains have been successfully used for fire and smoke protection for some time in elevators, but their application for atrium design is relatively new in the united states. A passive smoke management system, or smoke containment system, incorporates smoke and fire-rated curtains to compartmentalize fire and smoke keeping it out of the paths of egress. This must be proved on a case-by-case basis, with the use of mechanical systems being referred to as an ‘engineered’ rather than ‘code-compliant’ solution. Supply of fresh air to the lower area of the building optimises smoke and heat exhaust ventilation efficiency.

For this reason, the terms smoke extraction and smoke/heat extraction (rwa) are often used synonymously. Our supply may comprise design and implementation of a ventilation and smoke removal system or a complete fire-fighting system. Apart from the ventilation and smoke removal system, the complete solution may comprise fixed fire-fighting systems, voice alarm systems, emergency and escape route lighting, as well as flammable gases detection systems. An electric smoke and heat extraction system has a central control system with an jumta logi integrated backup power supply to ensure operation even in the event of a power failure. The exhaust air openings (skylight dome or window) are opened by a motorised drive, which is triggered by connected smoke detectors and manual switches (also push-button detectors). Supermarkets and commercial centres may have several storeys connected by way of lifts and/or staircases.

Every building administrator is obliged to maintain fire protection systems. Maintenance of fire protection systems should take place as often as indicated by the manufacturers of these systems, with a minimum of once a year [1]. Once every five years, internal hydrant components should be maintained. For example, a fire valve installed in a partition wall with a ventilation duct attached on one side has a fire tightness, insulation and smoke tightness of not less than 180 min. Fire valves are most commonly found in sizes dn 100, dn 125, dn 160 and dn 200.

You'll enjoy a smoke-free, healthier, fresher environment with little maintenance required. Just keep your magnetic cells clean in electronic smoke eaters or replace the filters in  your media smoke eater on a regular basis. Concealed or ducted smoke eaters offer an unobtrusive way to remove smoke discreetly.

A multi-sensor, addressable detector connects the functions of a smoke detector and a temperature detector. The device operates in an active manner, which means that a growth of temperature results in increasing the sensitivity of the smoke detector. This solution ensures fast reaction of the fire alarm system independently.
