What does F.P.L.R stand for?

  1. Fire Panel Low Resistance

  2. Fire Limited Power Riser

  3. Power Limited Fire Alarm Riser

  4. Fire Protection Limited Riser

The correct answer is: Power Limited Fire Alarm Riser

F.P.L.R stands for Power Limited Fire Alarm Riser. This term is significant in the field of fire protection and alarm system installation. The acronym denotes a type of riser cable that is specifically designed for fire alarm systems, which limits the amount of energy that can be transmitted through the cable. This limitation is critical for safety reasons, as it reduces the risk of fire and electrical hazards that could arise from short circuits or other malfunctions within the system. By using Power Limited cables, installers ensure compliance with fire codes and standards, which is essential for the safety and reliability of fire alarm systems. The use of such cabling is crucial, especially in multi-story buildings where cables run vertically from floor to floor, as it helps in maintaining proper functioning during emergencies and also meets regulatory requirements for fire alarms.
