I'm going to be replacing a couple of smoke alarms here shortly and a debate

Yesterday our hard wired smoke detector in the basement went off, it didn't cause the one up[stairs to sound an alarm, so that has me thinking it is defective. Aren't the two of them supposed to alarm at the same time??? We replaced the battery and it didn't help stop the alarm. Tried calling the company's 1-800 number but was on hold for almost an hour. Eventually got it shut off by disconnecting it. Now worried the other one might not work.. Also, thinking maybe some battery only ones should be installed as well. Can't hurt! Any comments or suggestions are welcomed!
