Frequently Asked Questions
How many smoke detectors does a home need?
Guidance summarized by First Alert and the NFPA puts smoke alarms on every level, inside every bedroom, and outside each sleeping area, with carbon monoxide alarms on every level and near attached garages. Most homes need several units, not one.
Do I need a monitored security system?
Monitoring helps when nobody is home to hear an alarm or check a phone alert. Self-monitored systems can still work for smaller homes, but professional monitoring adds 24/7 response.
How often should I test safety devices?
Test smoke and carbon monoxide detectors at least once a month, and follow the manufacturer’s guidance for batteries and replacement. Monthly testing catches dead batteries before they matter.
