6 Pack of USI 2-in-1 Hardwired Smoke and Fire Smart Alarms with 10 year Sealed Battery

I just received my second order of dual smoke/ fire detectors from US Electric. My first batch (7) lasted all of ten years problem free. My recent replacements arrived within a week of ordering on line. US Electric has never disappointed for my electrical issues. They are reliable, trusted and great quality.

I have used this detector in a wired circuit with the MIC1509S CO model detector. They have shown themselves to work well over time. Even Consumer Reports rated the MI106S better than many other brands and models. The customer support and purchasing ability is also helpful.

Changing out the whole building to update current smokes

This is a great alarm. We have used these for 3 years now. No false alarms. No battery maintenance.

This was my second purchase from Universal Security Instruments, Inc. The items were received quickly and were in perfect condition. Their pricing was the best I found. I'm currently working on my third order. Great job. Thanks,

Full residence old Kidde smokes eliminated and replaced with Hardwired/10 yr battery USI with expanded features. Smokes have been in 2 days. Smooth change out and no false reads as of yet.

Easy to replace my 10 year old units. I called in and someone helped me to ensure that I purchased the correct units. Thank you!

Ordered 4 smoke detectors w/10 year battery. Process was simple delivery was quick and installation went without an issue. My second time dealing with Universal and I will continue to purchase from them.

Just what I needed

I installed two of these as replacements. The installation was simple and we haven't had any false alarms.
