Product Reviews
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!!!
Arrived quickly and was very easy to install.
Reliable and effective!
This only took five minutes per unit to install. I was so worried they would not fit.. I'm VERY PLEASED
Absolute Excellent Service. Thank-You
Ordered 7 smoke and fire alarms to replace old ones that were out of date. USI had a great price and the product in stock. Shipped quickly and arrived earlier than expected. Would recommend them to anyone and will use again.
We have been very satisfied with the quality and dependability of this product for over 10 years.

The quality of smoke and fire alarm USI-1204HA is very good.
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!!!
Fast shipping and happy with product. Would definitely return for additional detectors and recommend to others
Came in as expected in a timely manner!
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.
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.
all good
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!
From delivery on time to installation, there were no surprises. The product is exactly as advertised. Very happy with this whole ordering thru installation experience.
I ordered 3 replacement alarms for my new home. They worked perfectly and were easy to replace! They also arrived very quickly. Thank you
Product FAQs
The smoke alarm chirps to indicate a "low battery" condition, meaning the battery needs to be replaced. Battery powered smoke alarms will chirp a minimum of 30 days before the battery completely loses power.
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.
The flashing red light gives a visual indication that the smoke detector is functioning properly. It also indicates a working battery is connected to the smoke alarm.
When a green light is present on your smoke detector, it means that AC power is currently operating the alarm.
If the green light on your smoke detector is not on, it means the AC power has been interrupted to the alarm. Check the circuit breaker and AC wiring to make sure power is still reaching the smoke alarm.
When interconnected alarms are alarming, the smoke alarm which initiated the alarm, either by test button or sensing smoke, will flash the red LED light approximately once per second. The red LED light on the other non-initiated interconnected smoke detectors will not be lit but will sound the alarm.
The NFPA 72 standard states the interconnect limit is 12 smoke alarms and up to 6 other alarms (heat alarms or carbon monoxide detectors) for a total of 18 total alarms. With 18 alarms interconnected, up to an additional 6 relay modules may be interconnected (for a maximum of 24 devices).
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.
