security alarms for homes
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. We have set a profile that gives you 20 seconds before leaving the house and the alarm starting. By clicking the A button on the keypad the counter starts giving you the amount of time to leave the house. If the magnets of the magnetic switch get separated, by the opening of a door or a window depending on where it is installed, the internal invisible counter gives the user 15 seconds or 3 trials to set the password correctly or the alarm will go off. The alarm will remain firing until the password is set correctly.
