Questions & Answers

Can this be used to replace a USI CD-9795 without re-wiring? I cannot a fford an electrician to install a new one.

Asked by: Bjdial
I can't really answer your question, since I have never mixed different brands of smoke detectors. My assumption is that it would probably work, but you would have to test it. This unit does not require an electrician to install. These types of smoke detectors have 3 wires, a white, a black, and a red wire. You can match them up from the old unit yourself and install the unit yourself as I did. (always turn off the power before working on anything electrical) You may even try to see if taking the connector off of the back of the unit and simply replacing old unit with the new unit, the back connectors are usually universal. Try this first and see if it works. You should contact USI or the manufacturer of your old unit to verify that the units are compatible. Good luck.

Will this alarm detect propane?

Will this alarm detect propane?
Asked by: Dan
I don't think this model lists propane. I have seen another brand that offered both gases in one unit, so you might keep looking. Just FYI, if I remember correctly, propane gas is heavier than air, so you have to mount the detector low, not on a ceiling.

Can i wire a plug, and literally plug this in?

Asked by: Wilsonswoodworks
It comes with its own wiring harness. It doesn't plug into a standard receptacle. So you can bring an electrical feed to a standard switch box or ceiling fixture box, use wire nuts to connect the wiring harness to your electrical cable, attach the (included) mounting bracket to your wiring box, plug in the detector to the proprietary connector end of the wiring harness, and twist the unit onto the mounting bracket.

Customer Reviews

Universal Security Instruments AC Hardwired Iophic Smoke/Fire Carbon Monoxide and Natural Gas Alarm with Battery Backup is rated 3.7 out of 5 by 77.
Rated 1 out of 5 by from warning.....check the manufacture date of the alarm before purchase (on the back of the unit inside packaging) We recently purchased 2 of these alarms due to ours going off with warning beeps. After doing some research we learned these alarms are only good for 7 years, and they have a “limited warranty” of 5 years on the packaging. When after 1 month our alarm started to give warning beeps we took it down and discovered the manufacture date of the alarm was 2011. These were purchased less than 2 months ago. There is no manufacture date on the exterior of the package you have to open the box and look on the back of the actual unit. At almost 30$ each why is home depot recieving units manufactured in 2011. 8 year old unit which have an expected life of 7 years?

Rated 1 out of 5 by from I bought 3 of these less then 2 years ago, and 2 are already defective I put an addition on my house less than 2 years ago, and bought all new smokes/smoke CO detectors throughout my whole house. I bought these because they weren't cheap, and I figured id be getting what I paid for. Well, already 2 of the 3 CO detectors are defective and beeping all the time giving false alarms. Ive had my local fire department verify it because I didn't want to take a chance that they were actual real alarms. Ive tried contacting the manufacturer 4 different times now, and I haven't received one call back or an email. do your self a favor and DO NOT BUY THESE!!!!

Rated 1 out of 5 by from False alarms I bought two of these to replace my hard-wired smoke detectors; I installed one on each floor. Within a couple of weeks the upstairs one started to beep. This leads to the next problem.... You have to look through a 21 row table in the instructions to determine what it is trying to signal. Was it 3 beeps, 2 second pause, repeat or was it 4 beeps, 5 second pause, repeat? Also, you must check which LED is lit or off or blinking. So you look in the instructions for an illustration of the layout of the LEDs. Nope, there isn't any. I don't know about other people, but I cannot read the small plastic molded letters on the detector when it is mounted on the ceiling. So I get a ladder and climb up to determine which LED is which. After all that, I determined It was signaling a CO problem. However, the four other CO detectors in the house were silent - two CO detectors had a digital readouts of zero. I swapped the upstairs and downstairs detector, and within a few weeks, beeping again. Same procedure of looking through the instructions and getting out the ladder. This time it was signalling a GAS problem. I didn't smell the distinct odor of gas, so I swapped the detectors again. No beeping for either detector after the swap. Now, the problematic detector is upstairs again and within a few weeks it is beeping again. Same CO alarm and the other CO detectors in the house are silent. This detector is going in the trash. Two detectors, with one turning out to be problematic. 50% is not a good indicator of quality for me.

Rated 1 out of 5 by from Chirping noise will drive you crazy Thought I was being diligent & replaced all our 10 yr. old units with these new ones, 6 total. Within a week, one began chirping intermittently, waking the household. Replaced battery. Days later, same thing. Replaced the battery, & now two weeks later, the same chirping that never ceases! They are worthless & should be recalled! Will be removing all six & demanding a refund!

Rated 4 out of 5 by from Upgraded house fire detection system I bought this combo smoke/natural gas/CO detector along with several smoke detectors and a heat detector based on recommendations in an article in a consumer magazine. We had just bought a house where all of the smoke detector were about 10 years out of date. I added the heat detector and combo detector in the basement with the gas furnace and water heater. Everything was wired together so that all the alarms shriek at the same time. All of the smoke detectors are dual sensors - photo and ionized particle systems. A little more expensive, but well worth the peace of mind. It's been a month so far and no false alarms... The combo detector manufacturer claimed this unit was compatible with other wired systems. I checked it out after installation and found that it worked as advertised. I did a fair bit of research on home fire detection systems, I knew what I wanted & only HD had everything in stock at my local store.

Rated 1 out of 5 by from I would give zero stars if I could Worked for less than a year and constantly gave off false alarms for CO (always in the middle of the night!). Replaced batteries and continued to get false alarms. Contacted the company and they were less than helpful and charged me $11.00 for a replacement that I still have not received. While still waiting for a replacement another one of the alarms has also stopped working. Waste of money, just another worthless piece of garbage made in china.
