2 2 I B e n e fi t s Stirwys Pressure Differentil Systems Systemir is the leding compny in combining differentil pressure nd smoke extrcting in one system with EC technology. Ten benefits of electronic overpressure systems 1. Fster self rescue: Fire escpe stirwys re recommended even if other rrngements re permitted for escpe nd rescue routes. People evcution is fster through smoke-free stirwys or stirwys with less smoke the pnic risk cn be reduced. 2. Fster rescue by others: On electronic overpressure systems, the ir supply of the fns cn be switched to the mximum ir volume by firefighter's switch. This enbles pushing bck nd leding smoke wy, even t high fire tempertures. The pressure in the stirwy exceeds the stndrds limittion, nd time-consuming instlltion of mobile fns, llowing cler view, in mny cses is unnecessry. 3. More flexibility during fire-fighting opertions: Mobile fns plced in the building entry cn become "tripping hzrd" for emergency tsk forces, prticulrly with regrd to connections such s cbles nd hydrulic hoses. The overpressure ventiltion technology is not new. It ws invented during the eighties s n pproprite element within fire protection concepts for skyscrpers. The mnufcturer Systemir ws instrumentl in pushing the development of n importnt improvement: the electronic control for pressuristion ventiltion fns. This system provides higher security for self-rescue nd especilly for the fire brigde.

3 B e n e fi t s I 3 Nowdys, n ir-tight building with few lekges demnds higher requirements for the plnning nd instlltion of smoke extrction concepts. Not only re influences from outside, such s temperture nd wind, relevnt for the design of pressure differentil systems but lso smoke extrction fns which crete negtive pressure inside the building in cse of fire. This negtive pressure inside modern buildings cn no longer be neglected nd hs significnt influence on the pressure distribution in the building nd consequently on the pressure differentil systems. The ltest development of Systemir combines both systems into n overll concept with energy optimised EC technology. 4. Higher security for emergency tsk forces: High ir velocities combined with electroniclly controlled ventiltion reduces the concentrtion of flmmble gses nd hot ir in the zone on fire. This reduces the risk of bckdrfts nd delys flshover. 5. Higher building protection: With the possibility of overriding the set pressure with the electronic overpressure system fster ccess for the firefighters is enbled. This reduces fire dmges which cn be honoured by the ssurnce in certin cses. 6. Relibility: Electronic overpressure systems re not ffected by wind lods, snow coverings or pressure chnges due to cold or wrm supply ir. 7. Reduction of construction costs: Openings for ir outlets re not required. Control dmpers nd dditionl wether protection equipment re usully not necessry. 8. Reduction of operting costs: No complex djusting or clening of mechnicl control dmpers. 9. Stedy precision during life cycle: Electronic overpressure systems utomticlly compenste potentil lekges due to norml wer nd ter of the building. 10. Architecturl freedom: Huge ir terminl devices or high roof fns re not required. In cse of fire, smoke gses re dngerous thret to escping people nd cn lso endnger nd obstruct rescuers. Therefore, electroniclly controlled positive pressure units re the next step in fire protection. The firefighters cn use n ordinry switch to increse the supply ir fn volume to mximum ir volume nd therefore less mobile fns re necessry or even none t ll. Electronic pressure differentil systems re gret help for self rescue. They lso give n dditionl protection from smoke gses for the fire fighters during high fire tempertures, provide cler view nd llow fster pproch to the source of fire.

4 4 I Pressure Differentil Systems The stirwys pressure differentil system with EC/AC driven motors The pressure differentil system MUB-EC by Systemir nd its AC version needs no pressure relief unit due to its control chrcteristics. It offers complete solution with fewer components nd ctutors for the pressure differentil ventiltion in stirwys nd escpe tunnels s conventionl systems. The system is lso vilble with smoke extrction function* in EC nd AC design. The complete system s well s its components meets the requirements ccording to EN (Smoke nd het control systems prt 6: specifiction for pressure differentil systems). The djusted EC motor/ac motor regultion unit gurntees stndrdised regultion performnce plus very low energy consumption during the ventiltion process. Design Exmple: Our MUB-EC centrifugl fn unit is used for residentil buildings up to eight floors. The cpcity cn be incresed by prllel opertion of two or more units. Higher buildings normlly require severl supply ir units instlled t different positions in the stirwy. The self-regulting EC control pnel is connected to the fn unit vi 0-10V-signl. There is just one stndrd 230 V cble necessry for the control unit. The optionl on/ off switch of the MUB-EC ventiltion unit cn be directly wired to the 400 V power supply. Systemir's complete solution includes periferic controls like, connections for smoke detectors, mnul cll points nd fire indictor pnel. Systemir designs individul solutions for your ppliction. *Smoke extrction Optionl smoke extrct fn certified to EN (Smoke- nd het control systems prt 3: Specifiction for powered smoke nd het exhust fns).
