Study Notes
Fire Protection Systems
- Fire protection systems are standard building features that help control damage and protect occupants in the event of a fire.
- They can be active or passive, with active systems including features like automatic fire sprinklers and fire alarm systems, and passive systems using building compartmentalization through fire-resistant walls, doors, and coatings.
Fire-Protection System Goals
- The primary goals of fire protection systems are to:
- Save lives
- Save property
- Preserve business continuity
Post Fire Smoke Purge
- The post-fire smoke purge involves a series of fans and shutters that help eliminate smoke from a building, preventing further damage.
- It can include automatic ventilation from windows and doors to flush smoke from a building.
Auxiliary Radio Communication Systems (ARCS)
- An ARCS provides clear, reliable communication for firefighters who may be separated by smoke, thick walls, or other standard radio interferences.
Smoke Control Systems
- Smoke control systems use physical barriers and mechanical systems to limit the spread of smoke through a building, minimizing damage to the building and occupants.
Fire Command Systems
- Fire command systems evaluate, maintain, and communicate vital aspects of a fire, providing updates in real-time.
- They are used in emergency services to communicate and understand different emergency situations outside of fire control.
Components of Fire-Protection Systems
- Automatic fire sprinklers are an important component, activated by heat from a fire once it reaches a certain temperature.
- Standpipes are built into the initial construction of a building, providing coverage on every floor.
- Fire alarm systems alert occupants in the event of a fire, and are highly regulated by fire safety laws.
Fire Department Connections
- Fire department connections are used by firefighters to supply water to standpipes or supplement the building's existing water supply.
- Additional water can be sourced from a fire truck or a hydrant that can tap into the building's standpipes.
Maintaining Safety
- Maintenance is critical to ensure the reliability of a fire protection system.
- An improperly maintained system lacks reliability and true protection.
Alarms and Notification Systems
- Alarms and notification systems can do more than just alert occupants of a fire; they can also direct responders to the location of the alarm.
- This can be achieved with AutoCAD floorplan integration.
Suppression Systems
- Sprinklers are the most widely specified suppression system in commercial facilities, cutting the chance of death and average property loss from a fire by one-half to two-thirds.
- Alternative fire-suppression systems, such as gaseous/chemical suppression, may be used in situations where sprinklers are not feasible.
Detection Systems
- Modern smoke detection systems are more sophisticated, able to sense smoke and trigger the alarm system while differentiating between different alarm thresholds.
- Heat detectors can trigger alarms and notification systems before smoke becomes an issue.
Basic Components of Fire Protection Systems
- The basic components of fire protection systems include:
- Detection
- Alarms and notification
- Suppression
- These components work together to detect, contain, control, and extinguish a fire.
Test your knowledge on fire protection systems, including active and passive systems, designed to control damage and protect occupants in the event of a fire.
