COMPARTMENTING AND FIRE PROOFING SEALINGS

PRESSURIZATION SYSTEMS

FOR SMOKE PROOF FILTER AREAS

KM-QSLAVE-PLCMICRO

KM-QSLAVE-SF

DESCRIPTION

KM-QSLAVE PLC KM-QSLAVE PLCMICRO/KM-QSLAVE SF produce an over pressure to preserve the smoke proof filter areas. The system is made up of 4 units:

  • A. Control and management unit

  • B. Buffer battery board

  • C. Pressurizer (electric fan) with Brushless motor

  • D. Differential pressure gauge

 

USE

The system is used to save the safe areas in case of fire. It creates an overpressure in the smoke proof filter area, so that the fire and the smoke can’t spread from fire-risk zones to safe areas, when a fire proof door is opened.

 

FITTING

The control and management unit A is connected to the buffer battery board B. They are installed in the safe area. The differential pressure gauge is to be installed in the safe area at 6 ml of cable from the A unit. The C unit (pressurizer-electric fan) must be installed on the wall or on the ceiling with the impeller towards the safe area. An air-duct is to be connected to the C unit. Then duct, with D class joint, has to be protected against the fire and the air-intake has to be open-pit. The fire proofing of duct is guaranteed by                                 KM-FC120COVER, certified fire resistant according to UNI EN 1366-1. By aeraulic computation the dimension of duct is calculated according to DM of 13/11/1983 and European Standard UNI EN 12101-6:2005.
