Generic Magnetic Sensor Alarm Door Window Security System RL-9805

Wireless home window and door security alarm system that uses a magnetic sensor to detect unauthorized entry. These devices are designed to be a simple and affordable way to enhance security in homes, offices, apartments, or garages.

Key Features

• Loud Alarm: When the door or window is opened and the two parts are separated by more than 10mm, a piercing alarm sounds to deter intruders. Decibel ratings for these devices typically range from 90dB to 120dB.
• Easy Installation: Most models feature a simple “peel and stick” installation using included double-sided adhesive tape, requiring no tools or screws.
• Battery Operated: The units are typically powered by LR44 button cell batteries (often three are required).
• On/Off Switch: A manual switch allows you to activate or deactivate the alarm as needed.
