The alarm can be armed and disarmed with a standard four digit user code in our case. The master code is a step above a regular user code. 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.
