Design points of Smoke alarm with 10Y sealed battery

Here are some design points for a smoke alarm with a 10-year sealed battery:
Power source: The smoke alarm should have a 10-year sealed battery that does not require replacement during the life of the alarm.
Sensor: The smoke alarm should be equipped with a photoelectric sensor that can detect smoldering fires as well as flames.
Interconnectivity: The smoke alarm should be capable of being interconnected with other smoke alarms in the home so that all alarms sound when one alarm detects smoke.

Alarm sound: The alarm sound should be loud and distinct, capable of waking up occupants in the event of a fire.
Test button: The smoke alarm should have a test button that allows homeowners to ensure that the alarm is functioning correctly.
Low battery warning: The smoke alarm should have a low battery warning that alerts homeowners when the battery needs to be replaced.
Hush button: The smoke alarm should have a hush button that allows homeowners to silence the alarm temporarily in the event of a false alarm.
Tamper-resistant: The smoke alarm should be designed to be tamper-resistant so that it cannot be easily removed or disabled.
Installation: The smoke alarm should be easy to install, with clear instructions and all necessary hardware included.
Compliance: The smoke alarm should comply with all relevant safety standards and regulations.
