1 | SPECIAL THANKS
The Halo+ Smoke and Carbon Monoxide alarm with Weather Alerts was born after the 2011 EF-5
tornado in Joplin, Missouri, hit close to home for one of our co-founders. Today, Halo Smart Labs
is a dedicated team working to achieve our mission of making the environment in, and around,
every home in the world safer. Thank you for bringing that mission a step closer to reality with your
purchase of this Halo alarm.
2 | INTRODUCTION TO HALO
Halo combines industry-leading dual sensor technology (ionization and photoelectric sensors) to
detect both smoldering and flaming fires. It can also detect carbon monoxide (CO). Smart sensors
help differentiate between a false alarm and a real fire. In addition to detecting emergencies, Halo
can also send you mobile notifications when you are away from home*. Halo+ is the only smoke
alarm to deliver weather and disaster alerts, including tornadoes, floods, and hurricanes.
*not real-time
Halo detects products of combustion using the ionization technique. It contains a maximum of 1.0
micro curie (37kBq) of Americium 241, a radioactive material, distributed under U.S. NRC License
No. 32-35253-01E. The purchaser is exempt from any regulatory requirements.
Do not try to repair the smoke alarm yourself. If you have any questions about the operation or
installation of your alarm, please contact Halo customer service at (888) 434-HALO (4256).
This user guide covers the installation, testing, maintenance, operation and use of Halo and Halo+.
