What causes false Alarms in hardwired smoke detectors?

Last night around 2am, all three of the hard-wired (not battery powered) smoke detectors in our apartment went off. We were unable to use the reset buttons and had to physically disconnect them to get the alarm to go off.
There was no smoke or other sign of a real threat that could have set them off. I suppose it could have been low levels of carbon monoxide and that will be the first thing we'll try to rule out tonight.
Any other ideas as to what could have caused this and what we should do? I've had smoke alarms go off when they run out of batteries before, but never anything like this.
