2. Existing high-rise structures
When were Life Safety high-rise structures built?
Since 1975
When were Existing high-rise structures built?
Before 1975
What is the characteristic of Life Safety high-rise buildings?
They generally have the most modern fire protection facilities available.
All Life Safety high-rise buildings have the following components (7)
- A Building Control Station or fire control room;
- Standby power and light for emergency operation of the life safety system;
- A fire department communication system;
- A public address system;
- Elevator safety provisions;
- A combined standpipe system;
- A central station alarm system.
What is the significance of the Building Control Station or fire control room?
It is the focal point in the Life Safety buildings for fire department operations.
The Building Control Station or fire control room usually contains what components? (7)
- A voice communications panel for fire department communications;

- A standard hard-wired telephone;
- Controls for the building’s HVAC system;
- Fail-safe stairway door release controls;
- Displays which indicate the status of the building’s fire alarm, HVAC, elevators and stairway door release system;
- Building emergency operations manual.
In Existing high-rise structures, what might they have instead of a Building Control Station?
They may have a lobby console staffed by building security personnel which contains some of the features found in Building Control Stations.
What must all Existing high-rise structures have? (6)
- Two means of exit from each floor;
- Keys to locked stairwell doors;
- A means of ventilation the structure (operable windows, fixed tempered glass, or mechanical ventilation);
- Elevator safety provisions which allows fire personnel access to each floor at all times;
- A Class I and Class II standpipe system, a Class III standpipe system, or a Combined system;
- An approved warning system or public address system.
What is required in buildings of more than 150 feet in height?
A public address system.
A public address system is required in buildings more than what height?
More than 150 feet in height.
What is each high-rise building required to have?
An Emergency Operations Manual.
Where is the Emergency Operations Manual generally located? (3)
In the
- Building Control Station;
- Security console; or
- The building engineer’s office.
What information should the Emergency Operations Manual contain? (3)
- Pertinent phone numbers;
- Floor plans of the building;
- Other useful information that could be useful to the fire department.
What is a standpipe system?
A wet or dry system of piping and related equipment designed to provide water exclusively for fire fighting.
What are they classifications of standpipe systems? (4)
- Class I - dry
- Class 2 - wet
- Class 3 - combination
- Combined Sprinkler-Standpipe systems
In what buildings are Class I standpipe systems found?
Older high-rise structures four or more stories tall.
What are the characteristics of a Class I standpipe system?
It is a dry system with water supply and water pressure delivered by a fire department pumper through inlet connections.
What is the minimum requirement for the FDC of a Class I standpipe system?
Two 2-1/2 inch inlets.
What is the required reach of a Class I standpipe system?
All portions of the high-rise structure must be able to be reached by a 30 foot stream from a nozzle attached to 100 feet of hose.
