Which statement is TRUE about residential fire alarm communicators?

1. Requires only one communication path

2. Can only function with phone lines

3. Must have two communication paths

4. Requires continuous monitoring

The correct answer is: Requires only one communication path

The statement that a residential fire alarm communicator requires only one communication path is true because these systems can operate effectively with a single communication method, whether that be a landline, cellular network, or internet connection. Many modern residential fire alarm communicators are designed to transmit signals about alarms or system status via a single channel, as long as it is reliable and meets the necessary regulatory requirements. It is important to note that while having more than one communication path (like both cellular and landline) can enhance the reliability of the alarm systems, it is not a strict requirement for functionality. This flexibility allows homeowners to choose the communication solution that best fits their needs and circumstances without being constrained to multiple paths. Thus, the correct answer highlights the adaptable nature of these residential fire alarm communicators in terms of connectivity.
