  1. A heat alarm ✔
  2. A standard smoke alarm
  3. A carbon monoxide alarm

Why: Smoke alarms are not required or designed for garages. Temperature changes, humidity, dust, fumes and insects can set them off. Heat alarms are made not to be affected by these conditions.

Huh, didn't know that: Many heat alarms can interconnect so the home's smoke alarms also sound when the heat alarm does.
