When connected via Smart Interconnect and a CO is alerted will only KN-COSM-ib give a vocal gas warning & the other smoke only units say nothing?

If installed correctly, when one unit is activated then all units will alarm. The value of this is that you will be fully warned when a distant hazard is detected. I'm sure that you'd want to know (while sleeping in the master bedroom), that there's a problem brewing in a bedroom on the far end of your home. For this may be the bedroom of your sleeping child. When I installed my new smoke/CO units one-at-a-time, I tested after each install. When I pressed the center test button, my new and old (smoke only) detectors all fired.

It seems like I recall that when testing the units, if one alarmed they all would. They worked fine. Mine just ate through batteries ridiculously fast even though they are hardwired to an AC power source

The unit has a pilot light and thermocouple. If the gas supply is interrupted, the pilot light will go out, which will inhibit the gas flow.

model #CO400 (carbon monoxide) conforms to ANSI/UL standard 2034 and model #SA303 (smoke alarm) conforms to ANSI/UL standard 217

That's worth a call to BRK/1st Alert. Since the interconnect I've wire runs from unit to unit, the battery-powered units should be able to send the signal, but I don't know for sure.

it does not set off the smoke alarm,the Oxy or C dioxide or mono alarms.There does is an aroma with it, which I have found is not that bothersome when I burn a candle.This is I guess that 1% that is note, it does say "I think" 99% ventless, I do love mine as using it does reduce the overall heating cost, on med it heats most of the 3 bedroom house.The blower works good and I am happy with it.....

You need a z-wave hub for it to work doesn't have to be smart things. It will need a hub to tell it's been triggered

Yes. This model "acknowledges" the EOM (end-of-message) data burst signal that sounds after the voice message concludes - the radio will go silent afterwards and return to "standby mode" until the next alert is received (based on user-programmed settings). If the unit is programmed to function in "voice" alert mode, it will respond this way every time. For me, when purchasing a S.A.M.E. WX alert radio, this feature is a "must have"! All S.A.M.E./E.A.S. alerts in the U.S.A. are formatted using the following protocol: [header codes][attention signal tone(s)][voice message][EOM codes]. Yes.

These are designed to connect to each other not to other brands and types of alarms. We have other existing units which will be triggered their own by smoke but will not chain react with the kiddes. The units are bought of same brand and set up to trigger each other from a different part of house or close houses , garages or sheds...So a garage unit could alarm in your home to notify you if as soon as a fire was causing smoke and before your car burned up.

The display is blank but you can see the 2 buttons under the display panel - the one on the left side is a test button and the one on the right shows the level in the display panel when pressed. So yes, when you press the right button and no carbon monoxide is detected it will display 0 in the display panel.

Item 4 in my instructions say: " 1) Alert - Beeps when a sensor is activated, corresponding zone LED will also flash.2) Alarm - Sounds an alarm when a sensor is activated, corresponding zone LED will also flash.3) Off - No audio sound will be emitted when sensor is activated. Zone LED will flash to indicate the activated sensor."As far as I see, there is no adjustment, not even a speaker grille to cover.

fire always brings Carbon monoxide. So if there is fire this will always go off. Can it replace a smoke detector > no just like smoke detectors can not detect CO.

I don't have a manual, however, I can say that mine ran several months without incident of CO, and I was venting the exhaust indoors. It was an unoccupied indoor garden, but it did have a CO monitor to make sure there were no dangers during watering times and such. I would use a CO monitor around any burning appliance now. We have the technology and it's fairly inexpensive. But in any case mine burned Clean if that helps your decision. I wouldn't vent it against manufacturer specs like I did,however mine performed fine.

Well it works with the 2 gig zwave control panel, but specifically I believe it communicates via 900 mgh tot he panel. Zwave is when you are turning thing on/off up down like a light switch or thermostat. Those zwave control instructions travel on a different wavelegnth than the smoke and co2 detectors.

this only detects smoke/steam; it does not detect carbon monoxide. It would be useful anywhere that you can hear it.

the 2 old units I replaced were Lifesaver Model 1255 - I think most units are standardized to communicate over the 3rd wire so all alarms connected together sound when any one goes off. If you don't require that feature, I think any standard 2 wire unit can replace any other. See this link to help in deciding if you want photo or ion (or the combo unit I bought) https://www.nfpa.org/safety-information/for-consumers/fire-and-safety-equipment/smoke-alarms/ionization-vs-photoelectric

I unplugged mine and threw it away because it gave many false alarms. The unit, and others like it according to comments on the Internet, are too sensitive. Hair spray, perfume, etc. may set off the alarm. Many pressurized cans use propane as the propellant, so it's not actually a true false alarm because propane is in the air but all that beeping was too much to deal with.

The short answer is "Yes". However, the unit may be too sensitive and sound the alarm because of the carbon monoxide gas emitted by your vehicles. I use mine in the kitchen area of a park model mobile home to detect any propane leakage. Any inconvenience caused by a false alarm is insignificant when compared with the alternative.
