CBC news reported on July 24th that humid weather is causing smoke detectors to go off all over the Halifax Regional Municipality, including three false alarms at the Halifax infirmary. Halifax Regional Fire and Emergency said on Monday alone it had to respond to 52 calls across the city. Of those, more than half of them were because a smoke alarm was triggered by humidity.

"When humidity is high, we respond to a lot of calls," said Kevin Reade, a division commander for Halifax Regional Fire and Emergency. Reade said a certain type of smoke detector — called an ionization detector — often mistakes humidity or steam for smoke.

Troy has a line of photoelectric smoke detectors that compensate for environmental change. Download the brochure below to learn more.
