NICET ITFAS-Level-1 Exam With Confidence Using Practice Dumps

McCulloh transmitters are part of older fire alarm systems but are still maintained in some jurisdictions. Inspection focuses ongeneral condition,correct system status, andlocation verification.

NFPA 72 (2022), Table 14.3.1 — Inspection Frequencies:

UnderMcCulloh Transmitter:

“Inspect physical condition”

“Verify location”

“Confirm system normal condition”

“Distinct waterflow condition” refers to alarm testing and isnotpart of theinspectionphase.

Correct answers:

Physical condition

System normal condition

Verify location

===========

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

===========

When aDACTis the only method of off-premises signal transmission, itmustbe connected totwo separate telephone linesto ensure redundancy in case one line fails.

NFPA 72 (2022), Section 26.6.4.4.4.1:

“DACTs shall be connected to two separate phone lines (one primary, one secondary). Loss of the primary line shall result in a supervisory signal.”

This redundancy ensures system reliability when using traditional telephone-based communication.

Correct answer: D. Two separate phone lines are required
