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.

Awesome Smoke & Fire Detectors

I purchased 6 USI Smoke and Fore detectors for my daughters home. Installation was a breeze. The hardest part was trying to find the correct circuit breaker to turn off prior to install. All work perfectly. She and I couldn't be more pleased. Thank you USI.
