Replacement for 20 year old USI detectors

Didn't know I had to ever replace these but upon changing the battery on an original one that came with the house, it said 2004 and replace every 10 years. I ordered these as the new replacement for the old part number. Came as promised. I had to rewire the connection to fit the new plug design. Came with 9 volt batteries. 9 of the 10 went in smooth but the 10th one set off the other 9 after rewiring twice. I swapped it with the 9th one and it solved the problem. Not much else to say. I tested them and they beep. Hopefully good for another 10 years.

Easy install but harness has to be changed

The fire alarms were very easy to install but the harness changed slightly between the 5204 and 5304 models. The mounting bracket also had to be replaced as they were slightly different. If everything was same, it would have been just unhook and plug-in.

The little suckers were tricky to twist-snap together once up on the ceiling. Sure would have been nice if the screws were included as well. Otherwise they units arrived timely and weren't very expensive for replacements.

Model 5304

Purchased this item to replace two units previously installed by the builder of our home and that had reached their lifes end. The units were extremely easy to install. Only had to change out the mounting plate.

Hardwired alarm

The product arrived quickly and was simple to install. It was used to replace an alarm that had gone bad, due to age.

Direct replacement for an older model

Although the old model was over ten years old, the new model used the same electrical connections, which made that part of the installation easy. I did have to replace the mounting plate, but that was easy too. A big thanks to our local fire department for replacing the unit on a vaulted ceiling.
