Questions & Answers

Does this ever need to be replaced?

It won't stop beeping like every 30 seconds.
Asked by: Michele
Yes, if the display says end. That means that the unit has reached the end of its life.

When this is plugged in, can you use the other plug for something else?

The other outlet can be used while the detector is in use. Follow safety rules as indicated for the additional appliance.

Does the battery need to be changed it is plug into wall.

Yes, because if you have power failure, your carbon monoxide detector will still be operational.

I don't know but it have to to be 0. That's normal?

Asked by: Adina
Read the owners manual. You can download a manual here: https://www.utcccs-cdn.com/hvac/docs/2001/Public/0B/900-0076.pdf.pdf (.pdf is duplicated, this is correct) The unit should read '0' under normal circumstances. It may read 30-50, considered low level, but should be of short duration. Read the manual for possible contamination scenarios. Any reading above '0' should be taken seriously, call a HVAC technician, vent the room as much as possible.

Plug-in Carbon Monoxide Detector with 9V Battery Backup and Digital Display is rated 4.7 out of 5 by 351.

I read that there is an internal clock that limits the unit to seven years of service and just pulled mine because I'm getting a chirp and low battery indication. It was manufactured 8/13/98 and had been displaying 0 ppm CO and flashing the decimal point to indicate operation. If the expiration clock feature is true, it must have been added after I purchased mine. The model number is 900-0076-00 and there are no expiration instructions on the unit. Other than battery replacement, the unit requires no special attention and hasn't even collected dust. Speaking of battery replacement, that is a weak point. Applying pressure to the access panel and sliding in the direction of the arrows may not work as well as prying it loose with a screwdriver. There is a remote, wired mounting option but I chose to plug the unit directly into an outlet. Very easy installation - plug and play. My old unit looks exactly like the one pictured but with a bit of yellowing on the front face at the power transformer location. I guess it's time for a replacement and unfortunately, electronics go to the landfill.

What I really liked about the old unit and this unit, is the display. One day it started beeping, I looked at the display and it said "end" or something to that effect. I looked that up in the tech sheet and it said that the unit is done. Time for a new one. Very helpful. Plus this is plugged in with battery backup so you don't get the nuisance low battery beeping.

I respond to literally hundreds of calls each year for "Carbon Monoxide Alarm Sounding". In a very small percentage of these calls we find CO, verified by very accurate monitors that we carry. The remainder of the calls are caused by, in order of frequency, dead batteries, expired detectors, or malfuncioning detectors. Please don't misunderstand me; CO is deadly and every time your CO detector goes off it should be taken as a true finding. Get out of the home and call 911. With that said, replace your batteries twice a year, replace your detector when the manufacturer says, and buy this detector. I can't remember the last time I found a Nighthawk that was wrong about CO. It's what I have in my house.

Easy to unpack, to understand the info, to set it up and simply plug it in. I like to see the CO reading displayed, and to be able to see it in the dark, and across the room. Very nice.
