  • Biggest technical problem in smoke detectors -- old battery

    Biggest share of standalone smoke detectors' technical failures happens because of non-functioning batteries. Detectors alarms about battery going bad by voice signal. It is clear, that signalling about low battery power using battery power is inconsistent and often leads to unnoticed empty batteries.
