PYRO - A 3000
PYRO - A 3000 (spontaneous ventilation equipment – spot equipment)
The fire damper PYRO - A 3000 is made from the dome rooflight with a reinforced construction and opening mechanism. Alternatively, as in the dome rooflights, a single, double or triple dome can be used and the sleeve heights are 300 and 500 mm.

PYRO A 3000/CO2 - PNEUMATICALLY CONTROLLED
The spontaneous venting equipment opens automatically by burning the thermal fuse if the temperature exceeds 68°C or 93°C, manually by striking a lever in the control room or by a signal from EPS. In the event of fire, the equipment opens by means of a pneumatic piston and CO2 cylinder. The opening and blocking angle in the end position is 165° or 105°. A 230 V electric motor can be added for the function of day ventilation that will be disconnected in the event of fire activation.
PYRO A 3000/EL - actuated electrically
The spontaneous venting equipment opens automatically by a pulse from the smoke or heat sensor, by manual opening by means of a fire button or by a signal from the EPS. The 24 V electric motor is used for opening the equipment in the case of fire. In the end position, the opening and blocking angle is 165° or 105°. A flap gate is used for venting with a minimum geometrical area of 2 m2 – staircase set. The main use is for venting staircases and protected escape routes.
