This is for a vacation house. Can I unplug the detector when I am gone for 2-3 months as no one will be ther to hear the alarm?
Asked by: Rob
Yes, this may be unplugged without it sounding alarm. During our summer months, since not running our furnace, both our detectors are unplugged. Plugged them back this autumn and they are working fine.

Does this unit chirp for the entire length of time when the power goes off? The power goes off in the neighborhood occasionally so I need a battery backup that would sound the alarm in the event of CO detection, but not chirping when we're dealing with a power outage.
Asked by: CrTex
I've never heard ours chirp. It used to be my mother's and I'm sure she would have called me if it chirped for her. Did you try putting in a new battery? Maybe the battery is weak and causes chirping, similar to a smoke detector. Also, I hope you test it on a regular basis to make sure it is working properly.

I've seen recommendations to have CO detectors at eye level to read the display. For plug in versions, how can you do this since most wall outlets are close to the floor? Is it acceptable from a safety and fucntional standpoint to use outlets that are about a foot from the floor? And this model in cany case doesn't have a display.
Asked by: AWA
I have not seen any contradictory info regarding placing the detectors along a regular floor outlet. These do not have any display except the indicator light which is easy to see. I found they actually make a fair night light when I get up in the middle of the night, but not bright enough to keep me awake.
