How do you turn on the door chime sound on security systems?

I use a Dynamark Secuirty system. I only turn the alarm at night but when I have in on during the day I turn it off, but when I open a door and windo the annoying door chime still makes noise. How do I turn that off also? I know my p code and everyting, I just need to know how to turn the chime noise off.
