Are Low Power Wireless Systems allowed for signal transmission in protected dwellings?

Low power wireless systems can indeed be used for signal transmission in protected dwellings. This option is correct because the National Fire Protection Association (NFPA) and local regulations have recognized that low power wireless systems can be utilized effectively in residential settings, particularly for fire alarm systems. These systems have been designed to reduce installation costs, minimize physical alterations to buildings, and facilitate network management.

Low power systems are typically sufficient to meet the communication and signaling needs without the complexities and constraints associated with wired systems. They can adequately provide coverage and ensure reliable transmission of signals in most residential environments, making them a viable choice for fire alarm installations, especially in retrofitting scenarios.

In contrast, the other choices suggest limitations or prohibitions that do not reflect current codes or standards. Some incorrectly specify that only wired systems are allowed or suggest that high power systems are required, which does not take into account the advancements and approved applications of low power wireless technology in fire safety.
