The alarm features four distinct modes and adjustable delay settings.
3.1. Alarm Modes:
The WSDCAM alarm offers four modes to suit various needs:
- Time Delay Alarm: Sounds a "Di-Di-Di" alert, gradually increasing in volume (0dB to 108dB), if the door remains open for the set delay time (3, 15, 30, or 60 seconds). This is ideal for refrigerators and freezers.
- Báo động chung: Activates a loud alarm when the door opens and stops when the door is closed.
- Báo động liên tục: Triggers a continuous loud alarm even if the door is closed, until manually deactivated. This mode is suitable for security purposes.
- Door Open Chime: Emits a "DingDong" sound once when the door opens, acting as a notification.
