My CO detector reached its end of life and needs to be replaced. Its a

Does any home center sell these or do I have to order online?
Get the Nighthawk with digital readout and battery backup, at WalMart
or HD. *You may need to install an electrical outlet high on the wall.
I use one in the utility room, kitchen and wall way. *My smoke
detectors are hard wired and work independently of the CO detectors.
I understand I can buy a standalone unit, but the one I have now works
off the 12V supplied by the alarm panel and plus it is linked to my
alarm panel with the NO/NC contacts with a supervisory resistor.

Try Macurco, but all the ones I've used have been 24V. *they might
have a 12V version though.

I'm not at work anymore, so I had a chance to DAGS and expand on my
answer...

a) looks like Macurco has been bought by 3M

b) looks like the CM-15a will work on 12/24V AC or DC and includes a
Form C alarm relay and a NC trouble relay (so if you are using a panel
that has a supervised alarm circuit it can correctly report a trouble
condition with the detector)

Thanks for the input, but I might as well get the same CO sensor as
before to cover the mounting holes and the hole where the wire comes
through on my wallpapered wall.
