  1. A fire alarm plan shows circuits labeled 'IDC-1' through 'IDC-4'. What does IDC stand for?

    Answer: Initiating Device Circuit

    IDC stands for Initiating Device Circuit, which is the NFPA 72 term for a circuit that connects initiating devices such as detectors and pull stations to the FACP.

  2. On a blueprint, a box symbol with 'FACP' inside it represents:

    Answer: Fire Alarm Control Panel

    FACP is the standard abbreviation for Fire Alarm Control Panel, the central brain of the fire alarm system.

  3. What is a 'keynote' on a construction drawing?

    Answer: A numbered or lettered reference that links a symbol on the drawing to a note or specification

    Keynotes use a number or letter on the drawing that cross-references to a note list, reducing clutter while providing detailed instructions.

  4. When a fire alarm drawing references 'SIM' next to a device symbol, what does it mean?

    Answer: Similar — install in the same manner as shown elsewhere

    'SIM' on drawings stands for 'Similar,' instructing the installer to replicate the same installation method shown for a referenced device or detail.

  5. A fire alarm blueprint shows the notation '(E)' before a device symbol. What does '(E)' indicate?

    Answer: Existing device to remain

    The prefix '(E)' on construction drawings denotes an existing condition—the device is already installed and is to remain in place.

  6. Which of the following best describes a 'one-line diagram' as used in fire alarm system documentation?

    Answer: A simplified schematic showing system components and their relationships using single lines for circuits

    A one-line diagram uses single lines to represent circuits and shows major system components and their interconnections without full wiring detail.

  7. On a fire alarm blueprint, what does the symbol 'EOL' with a resistance value (e.g., 4.7kΩ) indicate?

    Answer: The position and value of an end-of-line resistor on a supervised circuit

    EOL identifies where an end-of-line resistor is installed at the last device on a supervised initiating circuit to allow the panel to monitor circuit integrity.
