The IQ Smoke is connected to your IQ Panel and monitored 24-7, whether your system is armed or not. The IQ Smoke detects the presence of smoke using photoelectric smoke-sensing technology and conforms to UL 217. The IQ Smoke detects the presence of smoke particles as well as the rapid rise in heat that can come from a fire, even if there is no smoke. Because your system is always connected, you can receive a text or email alert if there are any problems, wherever you are.

• "Always on" technology ensures the sensor is monitored around the clock, whether your system is armed or not
• Ultra sensitive smoke sensor prevents false alarms while constantly monitoring
• Heat sensor detects the rapid rise in heat that comes from a fire - even when there is no smoke (like an electrical fire)
• Wall or ceiling mounted
• 3-5 year battery life
