The ZST series standard response sprinkler is the key unit in sprinkle system. It is consist of sprinkler, heat sensitive component (a glass bulb) and seal. It is installed in protection zone. The temperature of surroundings reaches the motion level when fire breaks up, the liquid in the glass bulb swells and then the glass bulb blasts. Thus, the seal drops and the sprinkler start to work.
The sprinkler can detect fire and spray automatically. It is widely used to protect the restaurants, hotels, hospitals, theatre, shops, buildings, warehouses, underground garages and garment factories.
