You want the probe outside the cage so it can not be moved or flooded. I put my probes between the mat and cage floor.
If the snake moves it up or off the floor the tstat will register low temps and ramp up the power there by causing the tstat to run away and get to hot putting your snake at risk.
Also if the snake flips its water or urinates on the probe the tstat will again register low temps and ramp up like above.
Snakes do not have ears. That's why they never come when called. So the alarm should not be a problem. Your Herpstat also has alarms you can set to let you know if the temp gets to hot or cold. I use mine, they are handy. I'll let you google how they detect things.
