5-Pack Window Alarms for Home Security, 120dB Door and Window Open Sensor Chime
1. Introduction
Thank you for choosing the AKOYU D12*5 Pack-US Window Alarms. This 5-pack of magnetic sensor alarms is designed to enhance the security of your home, garage, or apartment by providing immediate alerts when windows or doors are opened. With a loud 120dB siren, these alarms are effective in deterring intruders and notifying occupants. They are also ideal for monitoring child safety around doors and windows, and can be used for pool safety (though please note important safety information regarding pool compliance).
2. Safety Information
- Loud Alarm: The 120dB siren is extremely loud. Avoid prolonged exposure to the sound, especially during setup or testing, to prevent hearing discomfort.
- Battery Safety: Use only the specified battery type (2 AAA batteries per unit, not included). Do not mix old and new batteries, or different types of batteries. Dispose of used batteries responsibly.
- Installation Surface: Ensure the installation surface is clean, dry, and smooth for optimal adhesive performance.
- Child Safety: While these alarms can aid in child safety, they are not a substitute for adult supervision. Keep alarms out of reach of small children.
- Pool Safety Note: This alarm does not meet the UL 2017 standard and will not pass pool inspections. It is intended as an additional alert system, not a primary pool safety device.
