Smoke and Heat Extraction Skylight Domes

According to the European standard EN 12101-2, where heat and smoke extraction systems are required, 24V / 48V electric sunroof openings can be used together with SOLIDOME skylights. The principle of opening the smoke extraction mechanisms is that the drive housing is attached to the base of the sunroof and the traverse to the flap. The drive piston, which is inserted into the crossbar, opens or closes the flap by moving to one side or the other. The size of the mounting hole depends on the size of the drive housing and the power of the motor.

Electric drives are supplied with 24V or 48V DC, depending on the number of smoke extraction skylights, often combined into one group together with other drives into a common circuit and connected to the control panel. An opening / closing switch is installed where provided in the fire safety part of the project. According to the applicable requirements, the skylight is considered to be fully open in the smoke extraction position when the opening angle reaches 140 °.

SOLIDOME skylights can be fitted with pneumatic smoke extraction drives. The system is tested and complies with the European standard EN 12101-2. Pneumatic actuators are installed in the skylight in the same way as electric drives - the body is attached to the base and the traverse to the flap.

Opening after start-up - when a fire starts in a building, when the room temperature rises to a certain temperature, the thermal capsule in the actuator explodes and pierces the CO2 cylinder, which fills the system with gas and the piston opens the flap. The explosion temperature of the thermal capsules can optionally be 68 ° C, 90 ° C or 110 ° C.
