Help required in "Microcontroller based home security system project"

Hello Sir,
I m making this project but there are some problems that i face during the project,that were as follows:
1. Relay specification
2. Connection of relay to equipment like indoor light ,siren etc.and siren specification
3. Vcc value
sir please response me as soon as possible so that i can complete my project before submission date.
you can reply on my mail id::[email protected]

1. Relay is a normal 12V relay. You can easily find in market.
2. Common goes to neutral wire and Connect NO to Bulb so that when you energize the relay common connect to NO pin.
3. VCC is 12V

Hello Sir thanks for the fast reply but i have also one problem that when i draw the schematics on the proteus isis then it does notwork.
also i want to know the specification of siren.

There are 12v DC siren available in market you can use them. Can you tell me what part is not working? How did you simulate external events? Can you share your proteus schematic?

Hello Sir i have added proteus simulation files that was made by me.This simulation file is of MCU1. Please check them as no lamp or siren was glowing/beeping.
