1 door sensor has different alam siren tone

When I open my one door when my system is armed, there is the normal alarm siren that goes off. When I open my other door when armed, it is a faint beeping sound. That is not helpful if I'm in another area of the house. I want it to have the full alarm siren. The firmware is up-to-date and my base, keypad, and extender are all connected.
