A very effective trigger device for the MHA2000 home security system.
Magnetic door/window triggers provide security when attached to doors, windows or ranch sliders and are designed to trigger the alarm when these are opened. If the 'door chime' function in the control panel is enabled, you hear a 'ding-dong' when say the front door is opened when the system is disarmed. You can install as many as you wish to give your home the maximum protection.
You will need one sensor per door or window. They transmit up to 20~60 metres to the control panel depending on building materials.
