What is the minimum distance burglar alarm system wiring should be from electric power wire not in conduit?

The minimum distance that burglar alarm system wiring should be from electric power wire not in conduit is set to minimize the risk of interference and potential hazards. This distance, specified as 2 inches, helps to ensure that the alarm system wiring does not become affected by the electromagnetic fields generated by the flowing current in the power wires, which can lead to false alarms or improper functioning of the alarm system.

Maintaining this separation is crucial for both safety and performance reasons, as it reduces the likelihood of voltage "crosstalk" that could disrupt communication between alarm components. In doing so, it ensures that the alarm systems remain reliable and are less prone to errors due to interference from nearby electrical sources. This adherence to the specified distance is a fundamental practice in electrical installations to maintain the integrity of low voltage systems like burglar alarms.

The other distances offered in the choices are not compliant with the established safety codes that define this standard separation, highlighting the importance of understanding and applying the correct specifications in alarm system installations.
