NICET Level 2 Sprinkler Practice Test

The three general types of sprinkler heads are pendant, upright, and sidewall. Each type serves a specific purpose based on the installation environment and design requirements.

Pendant sprinkler heads are designed to hang from the ceiling and disperse water downwards. They are effective in areas where ceiling space is available, allowing for a wide area of coverage.

Upright sprinkler heads are positioned facing upwards, allowing water to spread in a downward pattern. These are often used in environments with obstructions or where mounting on the ceiling is not feasible.

Sidewall sprinkler heads are installed on walls and are designed to protect long and narrow spaces. Their unique placement allows them to effectively cover areas that might otherwise be challenging for pendant or upright heads to address.

Understanding these types allows for proper selection based on occupancy type, space geometry, and specific fire protection needs. The other options refer to different categories or attributes that do not align with the classification of sprinkler head types in a standard fire protection system.
