What do smoke detectors and smoke alarms have in common?

• A. Both can be interconnected
• B. Both are used for temperature control
• C. Both operate on battery power only
• D. Both are required in commercial buildings only

Answer: (A)

Smoke detectors and smoke alarms share the characteristic of being able to interconnect with one another, which enhances their functionality in fire safety systems. When interconnected, if one smoke detector detects smoke and alarms, it can trigger all interconnected units to do the same. This feature is critical for ensuring that the alert system operates cohesively throughout an area, providing warnings to occupants regardless of where the smoke is detected.

In contrast, while some smoke alarms and detectors can be powered by batteries, not all operate solely on battery power; many are hardwired into the electrical system of a building. Additionally, temperature control is not a function of smoke detectors or alarms; their primary purpose is detecting smoke and signaling the presence of fire. Furthermore, the requirement for these devices extends beyond commercial buildings; they are also mandated in residential settings to ensure safety for all occupants.
