Pre-paired out of the box — just mount and arm.

Key Features

• 108dB Loud Siren: An ear-catching alarm that immediately draws attention when a door or window is opened without disarming first — audible to nearby rooms and neighbors.
• 4 Operating Modes: Arm, Disarm, Emergency, and Doorbell modes — all switchable via the included wireless remote control.
• 49-Foot Wireless Range: Control the alarm from across the room or from another area of your home with ease (433MHz frequency for reduced interference).
• High-Sensitivity Magnetic Sensor: Triggers instantly when the door or window opens just ~1cm — ideal for doors, windows, cabinets, garage doors, and side/back entries.
• Versatile Use: Works as a standard entry alert, doorbell, pool gate monitor, or an entry notification for caregivers monitoring children, elderly family members, or visitors.
• Low-Battery Indicator: LED flashes on the host unit and the remote control dims or shortens in range when batteries are running low — so you're never caught off guard.
• No-Drill Installation: Mounts easily with the included adhesive tape — no tools or wiring required.
• Pre-Paired: Host unit and remote control are factory-paired — ready to use straight from the box.

Frequently Asked Questions

Q: Does the wireless door and window alarm need to be wired or hardwired during installation?

A: No — this alarm is completely wireless and requires no drilling or wiring. Simply attach the host unit and magnetic sensor to your door or window frame using the included adhesive tape strips. It runs on standard AAA batteries (not included) for the host and comes with a 12V 27A battery for the remote.

Q: Can I use this alarm on multiple doors and windows?

A: Each kit includes one alarm host, one magnet sensor, and one remote control — covering one entry point. For whole-home coverage, you can purchase multiple units. The 433MHz wireless frequency is designed to minimize interference between units, making multi-unit setups practical.

Q: What are the four remote control modes and how do they work?

A: The remote control offers four modes: Arm (activates the sensor so any door/window opening triggers the 108dB alarm), Disarm (deactivates the sensor for normal entry and exit), Emergency (manually triggers the alarm immediately), and Doorbell (plays a doorbell chime instead of the alarm, useful for front door notifications). All modes are accessible from up to 49 feet away.

Q: How sensitive is the magnetic sensor — will it false-trigger in windy conditions?

A: The sensor activates when the door or window is opened approximately 1cm or more, separating the host unit from the magnet strip. Normal vibrations from wind should not trigger the alarm as long as the door or window remains physically closed and the gap stays under 1cm. Proper installation alignment is key to reliable performance.
