Fire Department Connections
Sprinkler systems may require additional water pressure during a fire. Fire department connections, also called Siamese connections, are located on the outside wall of the building or near the street. Such a connection allows the fire department to connect its pumper directly into the building’s sprinkler system to increase water pressure and add water to the system. In a larger fire with many sprinklers operating, that would help maintain higher pressure to the activated sprinklers.
The fire department connections must be:
- easily located and accessible for use by the fire department
- clear of debris
- properly connected to the sprinkler system
- maintained in working order at all times
