You can set up monthly, semi-annual, or annual sound test reminders through the app to check the siren functionality. These detectors operate as standalone units without the need for an expensive smart home system. Made from durable white plastic, each unit measures approximately 10.5 cm in diameter and 4.5 cm in height, weighing 180 g per detector. The system is designed for reliable performance in residential environments, providing consistent smoke detection with minimal maintenance requirements.
