General introduction for how it works:

    This product normally installs near door if work together with our alarm host, you can armdisarm

alarm host by this keypad (through user’s code), and this keypad would show alarm host’s real

armdisarm status; If you armdisarm alarm host by remote controller or by alarm host’s keypad,

after that, the alarm host will send a wireless signal to this keypad to show its (alarm host) real
