Door sensor is one of the most common alarms, used for door, window, drawer alarm, mainly composed of two parts, a small piece is a magnet, the function is to create a small magnetic field, the other large piece is a door sensor As with the transmitter, the magnetic door switch is a "magnetron". When the magnet is close to the door magnetic switch (less than 15mm), the "magnetron" is in a disconnected state; when the magnet is removed, the "magnetron" is closed because there is no attraction of the magnet, and an alarm signal is generated at this time. The indicator light is on and transmitted to the alarm panel for alarm.
Door Magnetic Sensor Magnet Installation and Matters Needing Attention
The induction magnet is an important part of the door magnet. Whether the installation method is correct or not will directly affect the induction sensitivity of the door magnet. The induction magnet should be installed on the door or on the side that can move. When the door and window are opened, the induction The magnet is far away from the sensor to alarm.
Use the included 3M glue to stick the induction magnet on the door opposite the sensor body, as shown below.

Note: The installation of the induction magnet, "on the opposite side of the school" must be the same as the installation position of the main body of the door magnet.
After installation;
After installation, open and close the door to test the installation performance. Each time when opening and closing the door, the action indicator will light up, indicating that the installation is successful.
If the action indicator does not light up or is always on when the door is opened and closed, it means that the installation is unreasonable, and the installation position needs to be re-adjusted and the distance between the two is adjusted.
The above is the introduction of the installation and precautions of the door magnetic switch magnet. Our company mainly provides door magnetic magnet production and sales. Welcome to tell us the size and quantity of the magnet you want to evaluate the price.
