D. A pressure switch is an initiating device, and it must be connected to a supervised circuit (IDC or via an addressable module). Any circuit using a contact closure must have an end-of-line resistor to supervise for opens. The SLC module provides supervision, but if connected as a dry contact to the SLC, the wiring must still be supervised unless listed otherwise. Question 3 (Battery Calculation – Math Section) A fire alarm system has a standby current draw of 0.250 amps for 24 hours and an alarm current draw of 4.0 amps for 15 minutes. Using NFPA 72 requirements (standby plus 5 minutes of alarm), what is the minimum required battery capacity in ampere-hours (Ah) before derating?
A) Approve the submittal because 16 VDC is within the listed range. B) Reject the submittal and require a redesign because the design margin is insufficient. C) Issue a field change order to replace the power supply. D) Ignore it because voltage drop calculations are often inaccurate. nicet level 3 fire alarm practice test
However, the jump from Level 2 to Level 3 is notoriously difficult. The questions are no longer about “which wire goes where” but about “how does this code section apply to a high-rise building with voice evacuation?” This is where a becomes your most valuable study tool. The SLC module provides supervision, but if connected
A) 6.5 Ah B) 7.0 Ah C) 7.5 Ah D) 8.0 Ah

A) An abort switch must be provided with a 30-second delay. B) The alarm can sound immediately, but agent release must have a predetermined delay (e.g., 30 seconds) unless waived by the AHJ. C) There must be a manual pull station in the protected area. D) Voice evacuation must announce the countdown.
B. NFPA 72 18.4.2.1 requires that emergency voice alarm communications systems be designed to achieve acceptable intelligibility, and the designer must specify testing to verify intelligibility in all occupied spaces. Non-essential spaces may be exempted, but the standard does not limit testing to auditoriums. Question 2 (Codes & Standards) You are designing a fire alarm system for a warehouse that uses a deluge sprinkler system with a pressure switch to initiate the alarm. The pressure switch contacts are rated at 24 VDC, 50 mA. The fire alarm control panel (FACP) SLC loop provides 24 VDC, 100 mA. According to NFPA 72, what is the primary requirement for this connection?
