Multi sensor universal alarm
Reviewed: 01/22/2019 by Alan Duval
These multi sensor alarms were exactly what I wanted to replace three older wired smoke only alarms from this company. All of their alarms have always performed without any issues for the 17 years that we have been in our home. The time is coming up this year 2019 to replace all of the rest of the smoke alarms. I will be ordering them once again from USI Electric. I highly recommend the alarms from USI.

Fire and CO2 and natural gas alarm. My house heading out dated CO2 fire alarms, this new version also includes natural gas! They help me choose the replacement model that was appropriate for my home system. Thank you for protecting me and my family!

We require condo owners to have the 3-in-1 detector, which has since been discontinued. We ordered the new 4-in-1 detectors and they work seamlessly with an additional feature! Ordering more soon.

Great Product that makes my family safe
Reviewed: 08/22/2018 by Roger Avery
I have been using this product for several years and this is the first one that failed and needed replacing. BUT this was after the time period guarantee expired. Others have lasted longer but that's just my good fortune. It was very easy to replace but I did have to replace the disc that holds it to the ceiling as the design has been changed to make it easier to lock the alarm to the ceiling. This was provided all I had to do was remove/replace two screws.

Extremely good value for this many functions. Works with many other USI alarms. Wanted one alarm with CO detection in room with ventless propane fireplace that would communicate with other non CO alarms in the rest of the house that I was replacing. Easy to install, simply wirenut the leads on harness to your boxes wires and all set

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 the Alarm is exposed to 400 ppm of CO, it must alarm between 4 and 15 minutes.
- If the Alarm is exposed to 150 ppm of CO, it must alarm between 10 and 50 minutes.
- If the Alarm is exposed to 70 ppm of CO, it must alarm between 60 and 240 minutes.
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.
