Nighthawk 120v hardwired carbon monoxide detector

new without the box. was purchased for our old home but never was installed our new house had them already installed..

note this is a hardwire unit it needs to be wired into the house mains, this does NOT plug into an outlet

I have 2 of these available.

*** UPDATE *** these are Kiddie Brand i dont know why someone asked me why i listed them as Kiddie but when i look i dont say they are.. they ARE in fact made by Kiddie they are Model KN-COP-HW

Again, my late father bought these for his home and they were taken out of the package but he was unaware that his monitored DSC alarm system already had both Carbon monoxide and Smoke detectors in one so there was no point having these wired in
