Where are interior circuit conductors and interconnections between fire alarm transmission equipment and alarm receiving equipment located?

• A. Inside the building
• B. Outside the building
• C. In a separate enclosure outdoors
• D. In the attic

Answer: (A)

Interior wiring for fire alarm systems includes the conductors that run inside the building between the fire alarm transmission equipment and the alarm receiving equipment. Keeping these interconnections inside protects them from weather, tampering, and physical damage, and makes maintenance and inspection easier, which is why this path is chosen. Routes outside the building would require additional weatherproofing and protection and aren’t the standard for these internal interconnections. Attic routing is possible in some cases, but the intended placement for these interior links is within the building’s interior spaces.
