In wireless fire devices, the primary battery shall provide which signal?

• A. Provide a continuous alarm signal
• B. Provide a battery warning
• C. Provide a distinctive trouble signal
• D. Provide a tamper alert

Answer: (C)

The key idea is that power status from a wireless device should alert the system to a fault, not trigger an active fire alarm. The primary battery’s job is to signal a battery condition to the control panel, and it does this with a distinctive trouble signal. This lets the panel know there’s a power issue that could affect reliability, so maintenance can be prompted without confusing the panel with an actual fire alarm or tamper event. A continuous alarm signal is reserved for active fire events, and tamper alerts cover device removal or interference. A generic battery warning isn’t as reliable for system-wide conditioning and logging as a clearly identifiable trouble signal. So, the battery should provide a distinctive trouble signal.
