Question about Bosch D1255-05 Security Alarm Keypad
Here is your manual for your alarm keypad. "CLICK HERE"
After reading I think its a "trouble buzzer"
When a trouble event occurs, such as a service alert, it will emit a two tone warble until you enter "command 4"
If this helps just click the thumbs up.
Sincerely, Peter N.
