Pretty much once a day, now, sometimes twice, my CO detector goes offline. Last night it went offline in the night and then came back online about 15 minutes later; when it goes offline during the day the beeping from the panel doesn’t encourage me to see if the same will happen. For a while I thought it was that the battery wasn’t seated properly, because opening it up and pushing the battery in a bit more would seem to restore it immediately, but it doesn’t really seem that loose. Also about a third of the time I do that I get a tamper alert anyway, which is also annoying to deal with. What could the issue here be?
It looks like you have a tamper issue. The tamper on the back of the sensor isn’t being pressed in correctly or it may be a bad tamper switch.
On the back of the CO, you should see the part that pushes down the tamper. If you press it with your thumb, do you feel a click and does it clear the tamper from the panel? Can you double check you’re twisting it on all the way when installing it?
It seems to be twisted on all the way. And would that cause it to go offline and (sometimes) come back online?
would that cause it to go offline and (sometimes) come back online?
No, but cause and effect can go the other way around for those two statuses.
A tamper will not cause an offline status. Offline is an interpreted status, it isn’t something the sensor sends.
Offline means the panel has not received the heartbeat supervision signals it expects from that sensor lately, so it interprets that as the sensor cannot communicate.
If you tamper a device that is having trouble getting signals to the panel, the tamper signal may reach the panel but the panel may not get the signal when the tamper is restored, leaving that status in place even though the sensor is closed up.
How far away is that sensor from the panel?
Would you mind posting a photo of the inside of the panel showing the sensor daughter cards? There may be an issue with the antenna
Thank you. The white sensor RF antenna looks like it is running underneath the PowerG card in the panel. Pull that out and route it out the back of the panel, into the wall if wall mounted.
Does that resolve the issue with the CO signaling? Also just be sure the antenna is plugged firmly into the rf card antenna port.
done hopefully this will resolve it all, thanks
