Monitored 24-7, whether your system is armed or not, the smoke detector senses the presence of smoke, using photoelectric smoke-sensing technology. It also detects the rapid rise in heat from a fire, even if there is no smoke. Because your system is always synced with the Alarm.com App, you receive text alerts if there are any problems.
