ITFAS-Level-1 Exam Dumps : Inspection and Testing of Fire Alarm Systems Level I Exam

Signal priorities determine the order in which events are processed and displayed by the fire alarm system.

NFPA 72 (2022), Annex A.10.14.3 and system programming guidelines:

While not directly listed in a table, systems are programmed such that:

Alarm (including pre-alarm)has the highest priority

Followed bysupervisory, thentrouble, and finallyrestoral

Pre-alarm is part ofalarm initiation logicand is treated as high-priority due to its potential escalation.

Correct answer: A. Pre-alarm

===========

Control valve supervisory switches must be tested to verify that they send a signal when the valve position changes (e.g., valve is closed). NFPA 72 requires this to be doneannually.

NFPA 72 (2022), Table 14.4.3.2 — Testing Frequencies:

Control valve supervisory switch:

Frequency:Annually

Method:Operate valve control; verify signal annunciation.

Correct answer: D. Annually

===========

Ground-fault monitoring circuits are required on many fire alarm systems to detect when a wire has unintentionally contacted a grounded surface. During testing, the inspectorintentionally introduces a groundto verify that the panel can detect it.

NFPA 72 (2022), Section 10.17.1:

"Ground-fault conditions shall be annunciated in accordance with the requirements of this Code."

Testing method:

Thestandard functional testis tointentionally ground a circuit(typically using a known resistor) and verify the control panel indicates aground-fault supervisory signal.

Correct answer: D. Verify the ground-fault indication when circuits are grounded
