in THE MAIN WALL
it does not auto zero and is very sensitive I like it better than the UEI.

I use the NSI low level alarms but also recommend when people have a monitored alarm system they install a monitored co alarm.

Yes they have two high a threshold but if no one is home or the battery is dead at least there is some backup and the alarm will call for help itself.

    Supposedly made for or with Honeywell?

    A home security company says they install hard-wired Demco CO alarms. I already have two NSI units on main and second floors. They propose installing DEMCO in basement. Fine with me; just have to see the specs.

    One good thing about these kind of alarms is that they are monitored. Anyone hear of these units?

    Thanks,

    Are they


    UL listed?

    Keep in mind that you will probably not hear a CO alarm in the basement if you are sleeping on the second floor.

    Why do you feel you need a CO alarm there?

    i'll check on UL listing but

    since I work alot in the basement office seems like a good place to have an alarm --especially since that's where CO is likely to emanate from --gas boiler, gas hwh, gas dryer....
    Also being that it's monitored, if I'm away it would be in the best location to detect the CO the quickest and I would get a call.

    Guy wants to put it right outside boiler room. I'm going to guess it's only for high levels of CO. Wonder if someday NSI or CO Experts could work with the security companies and put in really good monitored units. That would cover alot of homes.

    Thanks Mark,

    Turns out it's a GE ESL 240-COe Carbon Monoxide Alarm

    listed as '70ppm/60-240 min'; functional at 15-80% humidity. (interesting--never thought of humidity as a factor.)UL 2034

    While it's nice that it's hard-wired and monitored by a security company, it doesn't seem much better than ones at the big box stores. And if they're as unreliable as those, you could get stuck with false alarms or unresponsive alarms.

    As far as the superior NSI units (not monitored) and the potential for walking into a house already with high CO levels, I have one unit in plain view as I walk into the house and would see any problems.

    Thanks,

    David
