Customer Reviews For The USI Electric Hardwired 3-in-1 Smoke, CO and Natural Gas Alarm (MICN109)
Awesome company got my items needed in a expedient fashion!
Good product great service
On time and works. All you can ask for.
The customer service person that helped me was so kind as to help me find the replacement product that I needed and when I received it, it was correct and it already had batteries inserted. This is usually not the norm. Thank you for the great service on a simple order.
Replaced oem. Works well
Our old smoke alarm kept chirping, even after multiple fresh batteries. Ordered a replacement easy to install. No more birdies!
They are very easy to install. We have a small home but it is very important to us. We have four regular fire alarms that are connected for safety. We appreciate your help and speedy shipping of these items.
Was easy to install replacing our old unit that was no longer working.
Happy it worked although it was a little difficult to get it to fit in.
We had a smoke detector go bad, found this online, and got it delivered immediately, a perfect match!
Great product
My multi-sensor device had failed. I went online and ordered the replacement and received it within a week. The device replacement was easy and a great deal more economical than what my security monitoring service quoted me. Great product and even greater service.
Replaced two smoke detectors with these units to make our home CA compliant for CO and CO2 detection . Items were shipped quickly and function perfectly.
Delivered in a timely manner and was easy to install.
Very good. I am happy

Perfect match to the old model that I replaced. The service is excellent.
easy to install-working well so far
Excellent product, easy to install and reasonably priced.
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.
This alarm has additional automatic features including a self-diagnostics check and a sensitivity adjustment for changes in temperature or humidity. The 9-volt alkaline battery (included) continues protection in the event of a power outage. This alarm features a front-loading battery drawer for replacement without removing the alarm from the bracket. Mount the bracket to any standard wiring junction box and use the large mounting base to cover imperfections in drywall. The plastic dust cover protects the alarm and (2) tamper-resistant locks prevent unwanted alarm or battery removal. For maximum protection, install an alarm inside every bedroom, outside every sleeping area and on all levels of the dwelling. The USI Electric MICN109 Hardwired Ionization, Carbon Monoxide and Natural Gas Alarm comes with a 7 year limited warranty.
This USI Alarm replaces the now obsolete USI-7795 and CD-9795 Wired-In 120 Volt Combo Smoke & CO Alarm (this model also utilizes the same mounting bracket and wiring.)
