EMB145 transition from taxi to take-off

Love flying in the EMB145 as SLF. I have a question about the transition from taxi to take-off.

My understanding is that @>25kts ground speed, the spoilers are deployed automatically (high speed taxi). So how does the aircraft know not to deploy them during the take off acceleration? I presume it's software coded to reconqise full power as apposed to taxi power? Just curious.

You re correct, the spoilers deploy only at low thrust levers angle.

Signal from the engine FADECs

To operate the spoilers with no engines running there is a test switch on the Maintenance panel which kids the a/c allowing the control handle to operate the spoiler panels
