evening, tried the manual and i cant see where or even if its a thing. when the alarm is on part set B, which is upstairs off and downstairs on, when i come down in the morning the countdown beeper is quite loud, I get up quite early for work and kids are always saying i wake them up when the countdown is triggered when i get to the bottom of the stairs. I dont want silent but just a very light beep to know the alarm is set. anyway to do this?
