My Safe-T-Alert CO/LP detector started false alarming about the same time that the allergy season hit in southern Arizona.
I ordered up a new co/lp detector (manufacture date: Dec 2015) and got it installed yesterday afternoon.
At 1:11 am the alarm goes off (just like the previous detector).
The weather is warm and the windows have been open all day and night. I'm on shore power and no propane or other combustion products are used.
I reset the alarm, back to bed. . .2.5 hours later and it alarms again.
I reset it. 3 hours later, alarms again.
So I put a soft pillow over it and it works fine.
There's no odor of propane, and all the windows open.
I'm wondering if there might be a correlation between pollen detection and temperature.
I question temperature because the detector alarms at night, when the temperature drops 20 degrees.
There's a Mesquite tree right outside the window and several other Mesquite trees on the property - just now going to flower.
Any thoughts?
