Not sure if I understand your question. If you mean the display (if yours has one) that should read 0, unless you are testing it with the test button. My NightHawk model 900-0014-04 reads 163 when the test button is pressed then sounds the alarm. Check the manual for your unit or look on the back of it for test instructions.
Most are calibrated for 200 PPM in less than 35 minutes and have an alarm response time of less than 90 minutes for a 100 PPM concentration of CO.

Why are my smoke detectors making so much noise?

I was at home, and all of a sudden all the smoke detectors started beeping at the same time, and when they stopped, they all stopped at the same time.

I am guessing that your alarms are all hard wired into your electrical wiring?? that would be the only reason they would all go off if there was no smoke. Do they also detect carbon monoxide? Perhaps you should find your manual or call the manufacturer
I am no electrician, but it sounds like it could be an electrical problem!!!
