Wireless flood sensors are used to detect the presence of water such as flooding. They are a good idea to have in areas of the home or workplace where flooding might occur as a result of taps accidentally being left on. This could be useful in a laundry or bathroom location.

Wireless door/window sensors are used to detect when a door or window is opened. These are called Reed switches. They consist of the Reed switch sensor and a small magnet. The Reed switch is placed on either the frame of the door/window and the magnet on the opening part of the door/window. When they are separated the sensor sends a signal to the alarm control panel, if the alarm system is armed it will be triggered. Designed to work perfectly with the Chuango H4 Alarm System.
