Tools and Hardware Reviews of Kidde KN-COB-LCB-A Tamper Resistant Plug-In Carbon Monoxide Alarm with Battery Backup
Customer Review: poorly conceived "tamper alarm"; failed after a year
Summary: 1 Stars
This unit has a "tamper resistant" feature that you most likely don't want, at least if you're buying a CO detector for your own family's use. Our unit broke in conjunction with this "feature", after barely one year of ownership.
The "tamper-resistant" feature is more like a theft detector -- it triggers an ear-piercing alarm if somebody tries to unplug the unit or even bumps it, and it's difficult to turn off. We learned this the hard way last night at 2am when my young son accidentally bumped our unit on his way to the bathroom, triggering the alarm and waking up everyone in our building for no good reason.
The instructions on the back of the unit don't explain what to do when this happens. So you don't know if you should evacuate the building or smash the thing with a sledgehammer and go back to bed. I ended up finding a screwdriver and removing the battery to shut it up, then using a different carbon monoxide detector to confirm there was no hazard in the room. That won't work for a lot of people.
Even today with the manual I couldn't figure out how to shut it up. It looks like when I reinsert the battery I should have two minutes to plug in the unit before the alarm sounds again, but that doesn't work - the alarm sounds as soon as I put the battery back in. Did I press reset too hard last night and break it? I don't know. I just know that my unit is essentially useless now. Not good.
For anybody who's wondering "why'd you buy a unit with a tamper alarm if you don't like it?", here are some points to consider:
1) When you buy it, it's not even clear it *has* such an alarm. The description on Amazon just says "tamper resistant feature"; that could mean anything. Who knows, maybe it's resistant to having bubblegum stuck in the air vent or something. The alarm is not prominent on the packaging or in the manual.
2) The alarm is not suitable for home use. You're not going to steal your own unit, right? A short chirp every minute might be nice to let you know it's accidentally been unplugged, but there's no way you need a continuous 85 decibel alarm to tell you that at 2am!
3) Even in a hotel or other setting where a loud anti-theft alarm might be valuable, it's still messed up. An honest hotel guest who accidentally bumps it won't know what the alarm means. A thief won't know to plug it back in and will probably just smash it to shut it up.
4) An 85 decibel alarm feels like it's coming from everywhere. In a home with several smoke and carbon monoxide detectors it's hard to tell which unit is activated. Yet the whole time this unit is blaring away none of the lights flash to indicate this is the one that's activated. This is lame.
5) You're not supposed to unplug the unit from the wall, yet the instructions are on the back of the unit. Doh!
On the plus side it successfully monitored the air in my kids' room for a year (I think, anyway). On the minus side, my kids now think a carbon monoxide detector is something to be distrusted.

AC-powered carbon monoxide alarm with
battery backup.
battery backup.
Features
It easily installs in any AC wall outlets, and it includes a battery backup (9-volt battery included) that provides protection even during power outages, when many CO incidences occur. The KN-COB-LCB-A uses advanced electrochemical sensing technology to monitor for carbon monoxide levels in your home. A tamper-resistant feature deters tampering or theft of the unit, alerting you if the unit has been unplugged or if it has come loose from the wall outlet.
Offering a clean, low-profile design, it features two color LEDs for at-a-glance status updates. The green LED shows that AC power is present and that the alarm is working properly. The red LED will illuminate when the alarm detects carbon monoxide and indicates that you and your family should move to fresh air. When the unit detects carbon monoxide, the alarm sounds four short beeps (rated at 85 decibels at 10 feet), followed by five seconds of silence, and then followed by another set of four short beeps. Additionally, when the battery runs low a chirp warning will sound for up to 12 hours to remind you to replace the battery. This carbon monoxide alarm is UL Listed and offers a five-year limited warranty.
