1What's the difference between ionisation and optical smoke detectors?
Ionisation detectors respond faster to flaming fires with visible flames, while optical detectors are better at detecting slow-burning, smoky fires. Most homes benefit from having both types, or choosing a dual-sensor model like some EI Electronics options that combine both technologies.
2Do EI Electronics detectors need to be interconnected, and is wireless better than wired?
EI Electronics offers both wired interconnected models and wireless radio-linked versions. Wired interconnection is more reliable and doesn't need battery checks, but wireless is easier to install in existing homes and gives you flexibility in placement.
3How often do I need to replace the battery in an EI Electronics smoke detector?
Most EI Electronics battery-powered models use 9V batteries that last 12 months under normal conditions, though some newer models use lithium batteries lasting up to 10 years. Check the specific model's specifications, as battery life varies depending on the type and model you choose.
4What's the coverage area for one EI Electronics smoke detector?
A single detector typically covers up to 60 square metres in normal conditions, but you should install one on each level of your home and in hallways near bedrooms. For larger homes or complex layouts, interconnecting multiple detectors ensures you get comprehensive coverage.
5Should I buy EI Electronics detectors with a heat sensor included?
Heat sensors are useful additions in kitchens and garages where cooking smoke or steam might trigger false alarms from standard smoke detectors. If you have multiple alarm points in your home, combining smoke detectors in living areas with heat detectors in kitchens gives you better overall protection without nuisance alarms.
