Customer Reviews For The USI Hardwired Ionization Smoke Alarm with Long Life Battery Backup 5304L

Good replacement smoke alarm

House was built with USI interconnected smoke alarms installed. Time to replace them, so I chose the 5304Ls with the ten-year battery for convenience.

Longer life

Longer life batteries make maintenance easier.

Easy Installation

These were easy to install as replacements to Model 5204 Smoke & Fire Alarms, because of using existing wires & plug-in.

No problems

Installed without any issues. No apparent defects. Would buy again.

smoke alarm 5304L

Very simple to install. The alarm replaced model 1204 and the base fits easily into the old ceiling fitting. USI has taken care to make sure the upgraded new devices can be used in the same location as the previous models.

Detectors were ordered to replace expired units. Installation was straightforward.

Great Customer Service

I ordered online, based on reviews and comments, the model I thought would replace my smoke alarms since they all went off at one time-my experience told me they had reached the end! Come to find out, I picked the wrong one! I called the company and they immediately advised the correct unit, placed the order for me and sent me RMA paperwork for return! All in just a few minutes! Wonderful customer service! I highly recommend this company!

VERY NICE PRODUCT AND VERY PLEASED WITH ENCLOSED WIRING TO MATCH AND MOUNTING PLATE YOU REQUIRE FOR INSTALLATION.LONG LIFE BATTERY IS SUPER VALUABLE TO ENHANCE PRODUCT !

7 5304Ls

Shipped promptly, easy installation, works as advertised.

At 70 I don't want to be climbing ladder to change batteries. Good idea making them last longer

This is the second time I have ordered replacement smoke detectors for our home. The replacement items have worked very well. No failures nor problems of any sort. Great products from a great company!

Easy to install. Arrived in a timely fashion.

smoke detector

It's a smoke detector with integrated charger and a rechargeable battery promised to last the life of the detector, which makes changing batteries obsolete. If it will last the 10 years as promised, it will be a great device!

Fire alarm model 5304L

Excellent replacement for older alarm model 1204 to retain inter-connectivity with a 10-year battery life.

Alarm replacements ii

Time to replace the 5-year-old alarms. These were perfect, brand-for-brand, with the added convenience of fitting the existing brackets!

Excellent Product with Excellent Service

Very pleased with our recent purchase of smoke detectors. Order was processed quickly and provided in record time.
