Free FACP Installation and Wiring Practices Questions and Answers

Question 1

What type of cable is typically used in fire alarm system installations?

Accepted Answer

FPL cable

Answer

FPL cable (Fire Power Limited) is specifically designed and listed for use in fire alarm system installations. It is engineered to meet specific fire resistance and low-smoke production requirements, ensuring it can maintain circuit integrity during a fire event. Using FPL cable is a critical safety measure and a requirement by codes like NFPA 70 (National Electrical Code) for fire alarm applications.

Question 2

Which method is used to prevent electromagnetic interference in fire alarm wiring?

Accepted Answer

Twisting and shielding wires

Answer

Twisting and shielding wires are effective methods used to prevent electromagnetic interference (EMI) in fire alarm wiring. Twisting conductors helps cancel out induced noise, while shielding creates a barrier against external electromagnetic fields. This ensures the integrity of the fire alarm signals, preventing false alarms or communication failures caused by electrical noise.

Question 3

Where should wiring for fire alarm circuits NOT be installed?

Accepted Answer

In elevator shafts

Answer

Wiring for fire alarm circuits should generally not be installed in elevator shafts due to the specific hazards and code requirements associated with these areas. Elevator shafts are often considered hazardous locations, and installing non-elevator-related wiring there can interfere with elevator operations, complicate maintenance, or be subject to damage. NFPA 70 (NEC) and other codes specify strict rules for wiring in such locations.

Question 4

What is the purpose of color coding in fire alarm system wiring?

Accepted Answer

Conductor identification

Answer

Color coding in fire alarm system wiring serves the crucial purpose of conductor identification. It allows installers and technicians to easily distinguish between different circuits, functions (e.g., power, signaling, notification), and polarities. This standardization improves installation accuracy, simplifies troubleshooting, and enhances safety during maintenance and repairs.

Question 5

What does the term 'supervised circuit' mean in fire alarm installations?

Accepted Answer

It monitors for faults

Answer

A 'supervised circuit' in fire alarm installations refers to a circuit that is continuously monitored by the fire alarm control panel for faults, such as open circuits, shorts, or ground faults. If a fault occurs, the panel will generate a trouble signal, alerting personnel to a problem that could compromise the system's ability to detect or report a fire. This supervision ensures the system's operational integrity at all times.
