Does this work on all door types?

Works best on: Smooth, clean surfaces like wood, metal, and painted doors/windows
Why can’t I enter Arming mode?
If doors or windows are left open prior to arming (causing the alarm unit and magnetic contact to separate), the system cannot be successfully armed. The alarm unit will flash once and emit a continuous, rapid beeping sound as a warning.
Why can’t I switch alarm modes?
Mode switching is not possible while the system is armed; you must first disarm the system to cycle through the three modes using the mode switch button.
Why won’t my alarm pair?
Please check if your battery has sufficient power. Pairing cannot be performed when the battery is low.
I have multiple alarms; how do I pair them with the remote control?
1. Press and hold the Volume+ button for 5 seconds. The alarm LED light flashes; when the indicator light remains constantly on, it enters pairing mode.
2. Press any button on the remote control. The alarm will beep to indicate successful pairing.
4 Modes, 1 Remote: This door alarm offers four modes—Doorbell Alert, Anti-theft Alarm, Everyday Reminder (for forgotten items), and Emergency Call—all easily controlled with the included remote. This single device flexibly covers multiple daily and security scenarios, including visitor alerts, home security, forgotten-item reminders, and emergency assistance. All functions are triggered by a high-sensitivity door sensor, providing smarter, more comprehensive protection and ensuring a timely, reliable response.
130dB Loud Alarm: The alarm triggers instantly when the door sensor and magnetic strip are separated by more than 1 cm. It emits a powerful 130dB security siren with a rapidly flashing red LED, effectively warning of potential intrusions and deterring intruders. Whether at home or away, this door alarm delivers a reliable audible warning when the door is opened, helping to protect your family and property.
5-Level Volume Control: Adjust the alarm alert volume precisely via the “+/-” buttons on the side of the door sensor. You can set a gentle level for daily alert, or a higher level for a loud, clear alarm that is impossible to ignore when the sensor is triggered. Customize the appropriate alert volume for different environments, such as nighttime rest or noisy daytime conditions, to avoid unnecessary disturbances and ensure important alerts are never missed.
Easy Setup, Wide Use: This wireless door sensor comes with strong adhesive backing for quick installation on doors, windows, cabinets, drawers, and more—no drilling or wiring required. One-minute setup saves time and effort. The door open alarm is suitable for homes, apartments, offices, garages, hotel rooms, and more, providing reliable security across multiple scenarios. Compact and portable, this door alarm is also an ideal on-the-go security solution, easily protecting doors and windows in temporary residences while traveling.Note: The installation location must be cleaned before installation.
