The Smoke and Heat Sensor triggers an alarm by the presence of a significant number of particles in the air or the temperature rising 15 degrees in 1 minute or the temperature exceeds 135 degrees Fahrenheit.
If the sensor is near a source of smoke or steam such as a kitchen or bathroom, you will need to move the Smoke and Heat Sensor. If the sensor is near anything that affects a change in the temperature, such as a heating or AC vent or a door or window to the outside of the home, the Smoke and Heat Sensor will need to be moved.
If these environmental factors do not apply, the Smoke and Heat Sensor does need to be cleaned of dust regularly as the buildup of dust on the internal filter will raise the sensitivity of the Smoke and Heat Sensor causing an alarm. Use compressed air or a vacuum cleaner to clean the inside of the Smoke and Heat Sensor. Note: do not remove the filter without first removing the batteries as it will cause the Sensor to trigger an alarm.
If the Smoke and Heat Sensor has been cleaned and it still triggers an alarm, reach out to Customer Support for more assistance.
