Fire Prevention Part V – 4/2007 Differential pressure systems Smoke and heat control of escape routes in accordance with DIN EN 12101-6

DIN EN 12101-6:2005 Smoke and heat control Part 6: Provisions for differential pressure systems – kits DIN EN 12101-6 is a mandated harmonized standard. Announcement in the Official Journal of the EC: 2005-12-14 / Publication in the Federal Official Gazette / Gazette of Coexistence phase until Thus as from 1st April 2007 DIN EN 12101-6 will be established law and applicable to differential pressure systems. This means: Differential pressure systems shall meet the following requirements on principle: Door opening force: Differential pressure systems shall be designed such that the door...

Differential pressure systems Smoke control pressure device with an integral automatical control valve Type: DV-RK1 Discharge fan with an integral automatical control valve Type: DV-RK2-EV Smoke control pressure device Type: DV1 Automatical control valve Type: RK2 Automatical discharge unit Type: RK2-JZI-DS-AH

The permissible pressure difference Ap in Pa (diagram 1) is determined by the appropriate door surface. The pressure difference supplies the energy for the flow through the open The achieved velocity does not allow smoke to flow into the staircase at certain temperatures (diagram 2). Velocity through the door in m/s

Differential pressure systems System example: Mechanical air supply with DV-RK1 Mechanical air exhaust with DS-RK2-EV RK1 pressure control valves open, staircase door closed RK2 pressure control valves open, exhaust fan DV in the by-pass mode Components: 1. DV-RK1 supply air device with an integral control valve 2. DS-RK2-EV exhaust ventilator with a roof base and control valve. For a secure discharge independent from the weather factors. 3. Multi-blade damper with SLC drive and weather protection grille for the wake 4. RKI-90 SLC smoke control damper 5. Appropriate number of ST-P-DA-STB...
