Name three examples of nationally recognized testing laboratories.
- Underwriters Laboratories Inc. (UL)
- FM Global
- Intertek (ETL Listed Mark)
These laboratories are known for their testing and certification services.
True or False: Testing by a nationally recognized laboratory is optional for ensuring operational reliability.
False
Testing by such laboratories is essential for guaranteeing the reliability of system components.
Fill in the blank: A _______ is responsible for testing components of a system to ensure operational reliability.
[nationally recognized testing laboratory]
Examples include UL, FM Global, and Intertek.
What codes should the installation of the system conform to?
The installation should conform to NFPA® 70, National Electrical Code®; NFPA® 72, National Fire Alarm and Signaling Code, and local codes and ordinances.
What are some basic components found in fire detection and alarm systems?
Basic components include fire alarm control units (FACUs), primary and secondary power supplies, initiating devices, and notification appliances.
What is the fire alarm control unit (FACU)?
The FACU contains the electronics that supervise and monitor the integrity of the wiring and components of the fire alarm system.
What was the former name of the fire alarm control unit?
The FACU was formerly called the fire alarm control panel (FACP).
What is the primary function of the FACU?
The FACU serves as the brain for the alarm system, receiving and processing signals from alarm initiating devices.
What does the FACU do with the processed signals?
It produces output signals that activate audible and visual appliances and transmit signals to an off-site monitoring station when provided.
How are power and fire alarm circuits connected in the system?
Power and fire alarm circuits are connected directly into the FACU.
What other components are considered part of the fire alarm system?
Remote auxiliary fire control units and notification appliance panels are also part of the fire alarm system and are connected and controlled by the FACU.
