Photoelectric Smoke Sensor with Built-In Heat Sensor

Receive fire detection alerts by installing the Qolsys IQ Wireless Smoke & Heat Detector (AKA the IQ Smoke). Used with any compatible control panel/receiver (319.5 MHz wireless frequency), such as a GE/Interlogix Panel (NetworX, Simon, etc.) or a Qolsys IQ Panel, this wireless, battery-powered Qolsys smoke detector uses a photoelectric sensor to detect smoke particles, while an integrated heat sensor detects the rapid rise in heat that can come from a fire, ensuring an alarm when a fie is present even if smoke does not reach the wireless heat detector. "Always on" technology ensures the wireless heat detector is monitored around the clock, whether your system is armed or not. The Qolsys smoke detector easily mounts with the included screws.

  • Photoelectric sensor detects smoke particles
  • High temperature detection alerts panel if temp exceeds 135°F
  • Designed to provide protection for up to 70-foot area
  • Compatible with 319.5 MHz wireless panels, such as GE/Interlogix or Qolsys IQ
  • Wireless range up to 600 feet from panel
  • Battery-powered, no wiring required

What Happens When Smoke or Heat is Detected

When smoke or a rapid rise in heat is detected, the wireless heat detector sounds a loud built-in siren (the ANSI S3.41 temporal 3 pattern) and sends a notification to the control panel. Using Alarm.com (requires optional subscription), you can also get a text alert. Additionally, a tricolored LED (red, yellow, green) on the detector provides visual indication of the detector's status. During an alarm condition, pressing the detector's hush button will silence the sounder.

Additional Features:

  • Using Alarm.com (requires optional subscription), you can get a text if smoke is detected or the temperature threshold is breached
  • Triggers alerts for tamper, tamper restore, alarm, alarm restore, low battery
