A solenoid valve connected to the control panel can activate the irrigation system with a delay of 3 minutes for standard. As an option, the solenoid valve can be dependent on a thermal sensor in order to avoid water spray in false alarm conditions, so even if there is a fire alarm the irrigation system doesn´t work until the sensor reaches 77ºC. In this case and for safety reasons, the irrigation system will not be activated until the following conditions meet together:
01 Fire alarm;
02 3 minutes delay;
03 Thermal sensor above 77ºC.
The number of sprinklers depends on the area of each system. The water conditions are the following:
– Water flow: >= 5,5 L/min/m²
