What is the purpose of a fire sprinkler system in a building?
Answer: To automatically detect and suppress a fire using water
Automatic sprinkler systems detect heat from a fire and discharge water directly over the fire to suppress or extinguish it.
What triggers the activation of a standard automatic sprinkler head?
Answer: The heat from a fire melting or breaking a fusible element
Standard sprinkler heads activate individually when a fusible link or glass bulb is heated to its rated temperature and breaks, releasing water.
In a wet pipe sprinkler system, what is present in the pipes at all times?
Answer: Pressurized water
Wet pipe systems maintain pressurized water in all supply pipes at all times, allowing immediate discharge when a sprinkler head activates.
What is a dry pipe sprinkler system typically used for?
Answer: Spaces subject to freezing temperatures such as unheated warehouses
Dry pipe systems use pressurized air or nitrogen instead of water in the pipes, making them suitable for areas where pipes could freeze if filled with water.
What should a fireguard do if a sprinkler head is accidentally activated and discharging water with no fire present?
Answer: Notify building management and the fire department, and locate the control valve to stop the flow
An unintentional discharge must be reported immediately; building personnel should close the system's main control valve and notify the fire department as required by code.
What color indicates a standard-response sprinkler head rated at 155°F (68°C)?
Answer: Red
Sprinkler head glass bulbs are color-coded by temperature rating; a red bulb indicates a standard 155°F (68°C) activation temperature.
