Smoke and Heat Sensor

The Smoke and Heat Sensor is always monitoring for smoke or a rapid increase in temperature, even when your system is disarmed. Follow the instructions below to get protected in no time:

• Select a location on the ceiling or wall of a common hallway shared by multiple bedrooms or in a central room in the home

  • Avoid placing the sensor in any of the following areas:

    • in a kitchen or garage

    • near a ventilation source such as an exhaust fan

    • near a shower or another potentially humid area

    • near a furnace, space heater or hot water heater

• Make sure the surface is clean and dry. If you’re placing the sensor on a ceiling, mount it 4 inches away from the wall. If you're placing it on the wall, mount it 4 to 12 inches below the ceiling

• Once you’ve removed the wax backing from the adhesive, press the sensor firmly against the wall or ceiling for 30 seconds
