Perfect replacement for FireX FADC 230
Moved house. Had 2 old expired FireX FADC 230’s. Perfect replacement. Simply disconnected plugs and plugged in new devices, even fitted the original base plate. Saved me the cost of getting an electrician out. Great value arrived fast, very happy.

It was a straight easy fit from old to new!
Took 4 mins to install, connections are the same! Good price! Loved it! Works a treat!

ideal replacement
Direct plug in replacement for the obsolete mains / battery back-up Firex FADC230. No need for any adaptor or rewiring. Haven't smoke tested it yet, but the test button proves it has a loud, piercing alarm. A good quality product. Same size as the defunct unit, battery life yet to be tested. Battery is now located on the underside which might make replacement easier than the fiddly door on the FADC230.
