The First Alert SA511CN2-3ST is an effective way to protect sleepers against the types of slow, smoldering fires that are most likely to occur at night. It is also wirelessly interconnectable with other compatible First Alert alarms, making it easy to set up a network of smoke detectors that will all sound if any are triggered.
