I am getting a false alarm from my fire alarm every time it is a cold morning and the heater kicks on.
My heater is a heat pump that has electric strip heaters which kick when the outdoor temp drops below 30 degrees.
My smoke detectors are System Sensor 4WTA-B sensors.
The alarm system has been in place for 5 years, with no false alarms. This year, I have had 3.
This morning I woke up to a fire alarm. The outside temp was 27 degrees, and there was a very light haze in the house.
It seems that there might be a little bit of dust that has accumulated in my heater over the summer, and it burns off when the electric strip heaters come on. I have experienced this burn-off in the past but it has never triggered an alarm.
I cleaned the smoke detector that alarmed, but could not see any visible dust on it.
Has anyone experienced this? Could the sensor be over-sensitive and need replacing? Or should I call a HVAC guy to vacuum the dust out of my unit?
