Electrical systems consist of devices that automatically trigger alarms in the event of a fire. These devices utilize sensors installed at various locations, all connected to a central control unit.
When a sensor detects signs of fire, such as smoke or high temperature, it transmits the information to the central control unit. The unit then alerts personnel by sounding an alarm and displaying the cause of the alarm. Water systems, in areas with high traffic and goods, draw water through pipes. Under high water pressure, the outlets for firefighting water are blocked with sprinkler heads.
The glass tubes of the sprinklers automatically burst under high temperature, allowing the sprinkler heads to evenly spray water to extinguish the fire.
