There was such an alarm. It failed.

In case you’re interested, there is an update on the story here:

The handler has been suspended. Preliminary investigation seems to indicate that he may not have activated the emergency sensor prior to leaving the dog in the car (for almost 4 hours). Human officer was on extra duty, which would by protocol require him to leave the dog at home in the kennel.
