SECTION 1: CODE REQUIREMENTS AND STANDARDS (30 Questions)
Q1: According to NFPA 72 (2026 edition), what is the maximum allowable spacing for spot-type
smoke detectors installed on a smooth ceiling in a corridor that is 12 feet wide?
• A. 30 feet between detectors, 15 feet from walls
• B. 41 feet between detectors, 20.5 feet from walls [CORRECT]
• C. 50 feet between detectors, 25 feet from walls
• D. 60 feet between detectors, 30 feet from walls
Rationale: NFPA 72 Section 17.7.3.2.1 requires spot-type smoke detectors on smooth ceilings
be spaced at a maximum of 41 feet between detectors and 20.5 feet from walls (half the spacing).
[CORRECT] Option B is correct. Option A (30/15) applies to heat detectors per NFPA 72
Section 17.6.3.1.1. Options C and D exceed maximum allowable spacing, creating dangerous
coverage gaps that could delay fire detection.
Q2: Under Texas Fire Marshal amendments to NFPA 72, what is the maximum time allowed for
fire alarm system transmission to a supervising station after the alarm initiating device activates?
• A. 30 seconds
• B. 60 seconds
• C. 90 seconds [CORRECT]
• D. 120 seconds
Rationale: Texas amendments require maximum 90-second transmission time to supervising
station. [CORRECT] Option C is correct. Option A (30 sec) is impractical for most systems.
Option B (60 sec) is NFPA 72 base requirement, but Texas TFM requires stricter 90-second
maximum. Option D (120 sec) exceeds both NFPA 72 and Texas requirements, creating
unacceptable life safety delays.

Q3: According to NFPA 72 (2026), what is the minimum audibility level required for fire alarm
notification appliances in commercial occupancies?
• A. 65 dBA at 10 feet
• B. 75 dBA at 10 feet
• C. 15 dBA above ambient noise level or 75 dBA, whichever is greater [CORRECT]
• D. 85 dBA throughout the space
Rationale: NFPA 72 Section 18.4.1.1 requires notification appliances produce 15 dBA above
average ambient sound level or 75 dBA, whichever is greater, measured at 10 feet. [CORRECT]
Option C is correct. Options A and B are incomplete specifications. Option D (85 dBA) exceeds
requirements and could cause hearing damage while violating OSHA exposure limits.
Q4: What is the maximum voltage drop permitted on notification appliance circuits (NAC) under
NFPA 72?
• A. 5% of nominal system voltage
• B. 10% of nominal system voltage
• C. 15% of nominal system voltage [CORRECT]
• D. 20% of nominal system voltage
Rationale: NFPA 72 Section 23.8.4.1 limits voltage drop to 15% of nominal system voltage
under maximum load conditions. [CORRECT] Option C is correct. Option A (5%) is
unnecessarily restrictive. Option B (10%) is common industry practice but exceeds code
maximum. Option D (20%) would result in insufficient voltage at remote appliances, causing
failure to activate during emergencies.
Q5: For fire alarm systems in Texas, what is the required battery backup duration for emergency
voice/alarm communication systems (EVACS)?
• A. 12 hours
• B. 24 hours in standby plus 15 minutes of alarm [CORRECT]
• C. 48 hours in standby plus 5 minutes of alarm
• D. 72 hours in standby
,3
Rationale: NFPA 72 Section 10.6.7.2.1 requires 24 hours standby plus 15 minutes alarm
operation for EVACS. [CORRECT] Option B is correct. Option A (12 hours) is insufficient for
extended outages. Option C (48 hours) applies to certain remote supervising stations, not
EVACS. Option D lacks required alarm operation time and exceeds typical requirements
unnecessarily.
Q6: According to NFPA 72, what is the maximum height for mounting manual fire alarm boxes
(pull stations)?
• A. 36 inches to center of handle
• B. 42 inches to center of handle
• C. 48 inches to center of handle [CORRECT]
• D. 60 inches to center of handle
Rationale: NFPA 72 Section 17.15.3 requires manual fire alarm boxes mounted with operable
part 42-48 inches above floor level, with 48 inches maximum. [CORRECT] Option C
represents the maximum allowable height. Options A and B are within range but not the
maximum. Option D exceeds ADA accessibility requirements and NFPA 72 maximums, making
stations inaccessible to wheelchair users and children.
Q7: Under Texas amendments, how often must fire alarm system sensitivity testing be
performed for smoke detectors?
• A. Monthly
• B. Quarterly
• C. Annually [CORRECT]
• D. Every 2 years
Rationale: NFPA 72 Table 14.4.5 requires sensitivity testing annually unless otherwise specified
by manufacturer or AHJ. [CORRECT] Option C is correct. Option A (monthly) applies to visual
inspections only. Option B (quarterly) applies to certain functional tests. Option D (2 years)
exceeds maximum interval and could allow detectors to operate outside calibrated sensitivity
ranges, risking nuisance alarms or failure to detect.
Q8: What is the required candela rating for visible notification appliances in sleeping areas per
NFPA 72 (2026)?
, 4
• A. 15 cd minimum
• B. 75 cd minimum
• C. 110 cd minimum [CORRECT]
• D. 177 cd minimum
Rationale: NFPA 72 Section 18.5.5.7 requires minimum 110 candela in sleeping areas to ensure
awakening effectiveness. [CORRECT] Option C is correct. Option A (15 cd) is general area
minimum. Option B (75 cd) is corridor requirement. Option D (177 cd) is required for hotel
sleeping areas with high ambient light or hearing-impaired accommodations, not standard
sleeping areas.
Q9: According to NFPA 72, Class A wiring for initiating device circuits (IDC) requires what
specific configuration?
• A. Single path wiring with end-of-line resistor
• B. Double path wiring with return loop to panel [CORRECT]
• C. Wireless mesh network topology
• D. T-tap configuration allowed throughout
Rationale: NFPA 72 Section 23.6.1 defines Class A as having return loop to panel, providing
redundant path. [CORRECT] Option B is correct. Option A describes Class B wiring. Option C
describes wireless systems, not Class A. Option D violates Class A requirements—T-taps are
prohibited in Class A IDC wiring as they create single points of failure.
Q10: For Texas healthcare facilities, what is the maximum allowable response time for smoke
detectors in patient sleeping areas?
• A. 15 seconds
• B. 30 seconds [CORRECT]
• C. 60 seconds
• D. 90 seconds
Rationale: Texas healthcare facility amendments require maximum 30-second detector response
time in patient sleeping areas for life safety. [CORRECT] Option B is correct. Option A is
impractical for most detector technologies. Option C and D exceed requirements for vulnerable
populations who may have limited mobility or consciousness.
