home securty system
It is used
to unlock the system, as well as programming or erasing a regular user code. Theoretically it can also be used to bypass some sensors. The default password set during the design, which is also the installation code, is 1234. Most alarm companies use the same installer code for all of their installations, and the vast majority will never give their installer code to a customer, for obvious reasons. As soon as we connect the 5V power source the alarm greets us with a welcome message displayed on the LCD then asks us to provide the password. Once entered correctly the green LED flashes accepting the code. If the password entered was incorrect the red LED flashes and the system gives you two further chances to enter the correct password. If both remaining attempts failed the system will lock. The only way to unlock the system is by clicking the star key for more than five seconds. This feature should be kept a secret between the user and the company otherwise anyone who knows it can unlock the system and keep trying to hack into
it. The keypad should be installed next to the entry door because it is programmed with a time lag, to permit you to exit when leaving, and enter on arriving home, without activating the alarm.
