Final answer:
Deluge sprinkler systems feature non-heat activated and non-automatic sprinkler heads, which provide immediate and widespread water distribution during a fire.
Step-by-step explanation:
The deluge sprinkler system is designed for special applications where rapid fire spread is a concern, and it floods an area with water in the event of a fire. This type of system is characterized by the following features:
- Non-heat activated sprinkler heads: All the sprinkler heads are open and will not operate individually in response to heat. This is beneficial when immediate and abundant water application is necessary.
- Non-automatic sprinkler heads: These systems require manual activation, often from a fire alarm or smoke detection system, rather than being triggered by heat from a fire.
These characteristics allow for the system to promptly drench the entire protected area when activated, providing a swift and strong defense against fire spread.
