Arduino Infrared Alarm System With Remote Button 1 and 2 Simulating Home Automation

I build a home security system using arduino, infrared and a remote. The aim of the project is to have a security system including some home automation features by pressing a simple button. In this case button 1 is simulating switching on/ off a light and button 2 is to switch on/ off a fan, While "A" will arm the system and the pin code will disarm the system. The red led simulating the siren for 5 seconds then the system arms itself again.
