You can also use the auxiliary relay options to connect it with other alarm systems. Remember to insert the Alkaline 9V Duracell® MN 1604 battery for backup power. When the alarm goes off, take immediate action to check for a fire. As for maintenance, test the detector regularly by pressing the test button. Keep it clean by gently wiping it with a dry cloth. Check the battery periodically and replace it when it's low. Also, make sure the detector is operating within the 40°F to 100°F temperature range for best performance.
