Review title: Not compliant with my current code
Product review: Just failed an inspection by the fire chief because these detectors do not make a voice announcement explaining the source of the alarm. Quoting from the Massachusetts requirements for combination detectors:"Acceptable combination smoke detectors and carbon monoxide alarms must have simulated voice and tone alarms that clearly distinguish between the two types of emergencies."3 vs 4 beeps is not considered a clear distinction.Do not get these detectors if you need to be up to code. On top of all this hassle, my return window expired and I sank $150 into 4 of these detectors that I can now throw away. The model that complies with Mass code is SC7010BV.
