October 19, 2021Smoke alarms from USI electric
I had 6 smoke alarms in my house that were 14 years old and they all connect with each other. I had one that did not quit chirping once I put a new battery in it. I did online research and found out if the alarms are too old you would have to replace them. After more research, and worrying about finding new alarms that would be compatible with my existing alarm base, I found USI Electric. They had a new alarm that would hook up with my old bases perfectly. Changed all the alarms in about 15 minutes! Very satisfied!!!

I looked for one at Lowes & Home Depot, neither had the one I needed, they actually told me I would have to replace all of them with another brand. I got online, found the exact one I needed. Ordered it, it arrived in 3 days!!! Perfect!!!

August 10, 2021SMOKE DETECTOR REPLACEMENT
This was an exact replacement for detectors that were 18 years old. Just unplugged the old and then plugged in new. No rewiring needed. Didn't know smoke detectors need to be replaced after 10 years. Started going off same time every day I guess as warning going bad. Hear about yearly battery replacement, but not about smoke detector needing to be replaced. Had Fire Dept here to check out and they didn't ask about age of detectors. Maybe they don't know. Ordering and receiving merchandise was prompt.

August 9, 2021Good products but deceiving shipping offer
The alarms fit our existing installations so they are easy to replace. The free shipping offer was not clear that it didn't apply to some locations and I was disappointed to find that it was not applied to my order.

August 7, 2021A replacement for an older model. Worked well
I had a couple of these that failed. This model was the exact replacement and it fit well with the older mounting system. Everything was explained in the instructions and I was able to replace the older units without any problem. So far these replacement units are working great!

AC powered smoke alarms with battery backup will chirp indefinitely assuming AC power is present; if battery power is low, or battery is removed; until a fresh battery is installed. Approved replacement batteries are listed on the back of each smoke alarm and in the user's manual.
Certain model smoke alarms with a silence button (designed to silence the alarm during a nuisance alarm) may chirp to indicate the smoke alarm is in the silence mode. The chirp will stop after approximately 8 minutes and the smoke alarm will return to its normal operation.
If battery backup alarms and non-battery backup alarms and accessories are mixed in an interconnect system, all devices without battery backup WILL NOT operate during an AC power failure.
CAUTION: USI alarms and accessories should only be interconnected with other USI alarms and accessories. Connecting devices from another manufacturer to USI devices may result in nuisance alarms, failure to alarm, or damage to one or all of the devices in the interconnect system. All interconnected USI alarms should be powered by the same fuse or circuit breaker. Smoke alarms shall not receive their power from a circuit that is protected by a ground fault circuit interrupter. Improper connection will result in damage to the alarm, failure to operate, or a shock hazard.
