- Weather conditions, controlled by rain detector, anemometer, thermostat sensor.
- Daily ventilation by push button or key switch.
- Obviously the emergency command has priority over ventilation. (Manual opening and closing are disabled.)
- The actuators are fed directly by a power supply unit. The batteries are use in case of power supply failure only.

Technical Data

The Voltage supply: 230VAC
Output : 24VDC
Nominal Current: 8A/16A
Expansion model GM-104 SU provided with booster batteries and controlled directly by the GM-104 control panel, allows to improve the number of actuators.

The GM-104 electric system for smoke and heat extraction are extremely versatile:
allows multi windows control or the smoke and heat extraction in case of fire, always enabling daily ventilation. A wide range of control panels detectors, electric chain actuators, rack actuators. Electric multi-locking actuators or any other accessory is available for the system installation.
