Hear me out here. I got my hands on a tiny "First Alert" CO detector. I removed the circuit from plastic case which includes a LED indicator and a piezo annunciator. The unit could easily be panel mounted with a test and alarm acknowledge button. After silencing the alarm the LED keeps blinking till the CO is removed.
Runs on a pair of 1 1/2 volt AA batteries. Any of you electrical guys know of a source for a very small 12 to 3 volt step down transformer to hard wire it? Would a few resistors in series be acceptable to lower the voltage? This thing is very sensitive.
