How to Test Heat Detectors

Heat detectors are designed to work in conjunction with smoke detectors to warn you and your family of a fire in your house. Heat detectors sound when the temperature reaches a certain high level, for example, 135 degrees Fahrenheit. Heat detectors do not detect smoke, gas or carbon monoxide. Test your heat detector once a week, or when you return home after being away for a few days.

Instructions

- 1
  Look on the face of all the heat detectors in your home for an LED light. The light confirms the heat detectors connect to and receive the house electrical current.
- 2
  Climb a stepladder and push the test button on the heat detector. The tester will sound for several seconds. If connected together, all the heat detectors should sound within two or three seconds after you press the test button on one detector.

  While you're standing on the stepladder, aim a heat lamp, blow-dryer, or heat gun at the heat detector. The detector alarms should sound within three or four seconds after you apply the heat source.
