Kidde acquired the manufacturer of Firex branded products in 2009. Invensys Controls no longer manufactures or supports these products. This website may contain some historical support documents, such as product user guides that may reference the Invensys Controls name or mailing address for product support.
If you own any of these products, they should be replaced with a current Kidde model.
If you are replacing AC hardwired Firex brand alarms manufactured prior to 2009, there is no current model that will fit the same wiring harness or mounting bracket.
Replacing alarms will require first changing the mounting bracket, and then either changing the wiring harness, or for certain Firex models, you can use the KA-F2 Adapter to avoid having to rewire to the new wiring harness.
When you change one of these older alarms, you will need to replace ALL devices attached to the interconnect line for compatibility. Follow the steps below along with your new user guide (included).
For more information about your specific alarm, refer to your user guide.
