Why Fire Alarm Systems (Art. 760) matters
Fire Alarm Systems (Art. 760) is a commonly tested topic on the Master Electrician License Exam because it covers fundamental knowledge required for competent professional practice.
Sample Practice Questions (5)
1. Where fire alarm cables are installed vertically through a floor penetration in a building (riser application), the minimum cable listing required is:
- FPLR (fire power-limited riser)
- FPL (general use fire power-limited)
- FPLP (fire power-limited plenum)
- CM (general communications cable)
2. An NPLFA circuit operating at 120V supplies power to a fire alarm control panel. This circuit must be supplied from a dedicated branch circuit that:
- Is identified at the panelboard as "FIRE ALARM" and has no other loads connected
- May share loads with general lighting on the same floor
- Must be on a ground-fault circuit interrupter (GFCI) breaker
- May be tapped from any available 120V circuit
3. A fire alarm designer wants to run PLFA cable and Class 2 (security system) cable in the same raceway. Per Article 760, this is:
- Permitted only if the PLFA and Class 2 cables are both listed and the fire alarm cable maintains its listing when installed together
- Always permitted without restriction since both are low-voltage
- Never permitted under any circumstances
- Permitted only if both cables are in rigid metal conduit

- The penetration must be firestopped with a listed through-penetration firestop system to maintain the wall's fire rating
- No special treatment is required for listed fire alarm cable
- The cable must be sleeved with standard EMT through the wall
- A metal plate must cover both sides of the penetration
5. Fire alarm cable installed in a plenum space (air-handling area) must be listed as which type?
- FPLP (fire power-limited plenum) cable
- FPLR (fire power-limited riser) cable
- FPL (fire power-limited) cable
- Standard THHN conductors in EMT
