How to find your model number.
For Fire Extinguishers:
The model number will be located on the label in the bottom right or left hand corner. It will say MODEL before it and give you a list of models.
For Smoke and CO Alarms: The model number is located on the back label on your alarm. To find it you'll need to remove your alarm from the ceiling or wall. Most alarms are attached to a mounting plate and can be removed by turning the alarm counterclockwise. See the alarm removal instructions for details. The number will be labeled MODEL.
Kidde Alarms: If you look at the back of the alarm, you will see the name of the product and the model number in bold text below the logo.
Firex Alarms: If you look at the back of the alarm, you will see where the text is split into two columns, with text on the left and text on the right. The model is the text on the top of the left hand column after "Model."
