What is a mains powered smoke alarm
Anka’s mains-powered smoke alarm is hard-wired directly into your home’s electrical system (240V) for continuous power but includes a battery backup (9V or 10-year lithium) to function during power outages, offering reliable, uninterrupted protection, and often requires professional installation by an electrician. These alarms provide superior reliability as they don’t rely solely on batteries and can be interconnected (wired or wirelessly) so if one sounds, they all sound, giving early warning throughout the home. Anka Security shares the main features and application scenarios of AC-powered smoke detectors.
Key Features Of Mains Powered Smoke Alarm
Power Source: Directly connects to your home’s main electrical supply (240V).
Battery Backup: Contains a backup battery (usually a 9V or a 10-year non-replaceable lithium battery) for power failures, ensuring it still works during blackouts.
Professional Installation: Typically requires a licensed electrician for safe installation.
Interconnection: Can be wired or wirelessly linked to other alarms, so all units sound when one detects smoke, ideal for larger homes.
Reliability: More reliable than purely battery-operated units due to continuous power and constant charging of the backup.
Application Scenarios Of Mains Powered Smoke Alarm
Often installed in new homes or during major renovations as a primary choice for safety.
Required by law in some regions for homes built after certain dates (e.g., after August 1997 in some Australian states).
Types of Backup Batteries
9V Alkaline: Needs annual replacement, which can be inconvenient.
10-Year Lithium: Lasts the life of the alarm, eliminating frequent battery changes.
