Learn About Security Doors and Windows
According to the police, a third of break-ins is through the windows. Hence in securing your home, it is important to look at ways to secure your doors and windows.
Strong, good locks and grilles should be your first line of defense, coupled with Home Security System that serves the function of deterrence, detection and alerting the relevant authorities. |
How the Sensor works?
The door or window sensor comprises two component: a reed switch (with the wires) and a magnet.
When the door is closed, the magnet pulls the metal switch closed so the circuit is complete. The current powers the relay's electromagnet, so the buzzer circuit stays open. When you move the magnet by opening the door, the spring snaps the switch back into the open position. This cuts off the current and closes the relay, sounding the alarm. |

Different Types of Sensors
There is a wide range of door and window sensors to cater for the different application and types of doors and windows. In general, they can be classified into:
- surface mount
- flush mount
- heavy duty
|
| Surface Mount Sensors
Surface Mounted sensors are mounted exposed on the surface of the doors and windows and are normally used where it is either not possible or too late to recess them into the door or window frames. |
 |
 |
| For mounting in center |
