About this item
- Instant Loud Alarm: When the door alarm and sensor are separated by more than 1.5CM, a powerful 100dB alarm instantly sounds, deterring children from sneaking out or alerting you to intruders. Pressing the SOS button triggers a continuous alarm, boosting security for homes, offices, shops, and garages.
- Versatile Modes: The door sensor alarm offers 4 modes: "SOS mode" (continuous alarm until disarmed), "Chime mode" (a "ding-dong" sound when opened), "Alarm mode 1" (alarm sounds upon opening and stops when closed), and "Alarm mode 2" (a 30-second alarm that continues even if the door/window is immediately closed). Adjust the volume easily using the volume button.
- Remote Security Control: The door alarms for your home include 2 wireless remote controls with a 50-meter range, allowing you to turn the alarm on/off or switch modes from a distance. In case of emergencies, such as an elderly person or child falling near your home or encountering danger, pressing the SOS button will trigger an immediate alarm for quick assistance.
- Simple Installation: The compact magnetic window alarms are easy to install in various locations using the provided stickers. (Note: Clean the installation area and place the sensor within 1.5cm of the alarm's arrow side.) The door sensor alarm requires 2 AAA batteries (not included), with an LED flashing every 3 seconds to indicate low battery.
- 36 Months Warranty: If the wireless alarm system isn’t working, check the battery and ensure it’s armed. If you encounter any problems in using the door alarm sensor, please feel free to contact our professional customer service team, enjoying TECKNET 36 Months Warranty (Registered Only).

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
