Three detection types in one ceiling position: heat, smoke and carbon monoxide. CO is the one people forget, and it is the one that kills quietly, so combining it with the fire detector means the coverage actually gets installed.
Built for the installer
The smoke sensor is a double-spectrum optical device that identifies smoke by particle size rather than simply reacting to anything in the chamber, and the chamber itself is a patented design that keeps dust, dirt and insects out. Those two things together are what stop a detector crying wolf in a dusty plant room or a kitchen.
The heat sensor adds a high-temperature alarm above 135F and low-temperature detection to UL 521, so it covers the fire signatures that produce heat before visible smoke. It reports to the hub over 905.0-926.5 MHz at up to 5,550 ft.
Key features
- Heat, smoke and carbon monoxide in a single ceiling position
- Replaceable batteries rather than a sealed unit discarded at end of life
- Double-spectrum optical smoke sensor with a patented dust-resistant chamber
- High-temperature alarm above 135F plus low-temperature detection to UL 521
- Up to 5,550 ft radio range to the hub or a range extender
System requirements
Requires an Ajax hub or range extender. Indoor use, IP20. Check local code for detector spacing and placement before installing.
