alarm in the direction of the “ON” arrow on the cover until
the alarm ratchets into place (this ratcheting function allows

should be lit when the alarm is operating from AC power.

information on what to do in case of an alarm. Add the
phone number of your emergency service provider (Fire
Department or 911) in the space provided. Place one label
next to the alarm after it is mounted, and one label near a
fresh air source such as a door or window.
