Condominiums, single family and two-family residences sold in MA must be inspected by the fire department to confirm the proper installation of smoke detectors and carbon monoxide detectors. They then issue a smoke certificate required for the closing. It is important for property owners to understand the MA smoke detector rules and different kinds of smoke detectors in order to comply (regardless of whether they are selling their property).
Different Kinds Of Smoke Detectors
There are two different kinds of smoke detectors, ionization and photoelectric. Each one has different pros and cons relating to recognizing smoke and flames.
Ionization detectors contain two electrodes and a constant current that runs between them. The presence of smoke interferes with this current which causes the alarm to sound. Ionization detectors are good at detecting flaming fires but does not discriminate between smoke and steam. Therefore, they are likely to issue false alarms if placed near kitchens and baths.
Photoelectric smoke detectors have a beam of light. The presence of smoke or fire can break up this beam and activate the alarm. It is very effective at detecting smoldering fire and is less sensitive to false alarms from cooking or shower steam.
