What type of smoke alarm is described as being battery operated?

A single-station smoke alarm is typically battery-operated, designed for individual use within a single room or space. This type of smoke alarm functions independently and can be installed without requiring extensive wiring, making it a practical choice for residential environments or locations where hard-wired systems are not feasible.

In contrast, smoke detectors and central station alarms usually involve more complex setups. Smoke detectors may be hardwired into a system that connects to multiple units or a central monitoring location, while central station alarms are designed for comprehensive monitoring across a facility, often involving a direct connection to emergency services and requiring a more sophisticated power source. Multi-station alarms can also integrate several units into a circuit that communicates with each other, often necessitating electrical wiring.

The self-sufficient design of a single-station smoke alarm, powered by batteries, offers ease of installation and maintenance for homeowners and ensures that smoke detection is available even during power outages.
