 If you purchased your smoke detector from the hardware store or your electrician, you likely have an ionization detector, while we recommend and install photoelectric smoke detectors.

Not all Smoke Detectors are Created Equal

In 2022 a fire broke out in a rowhouse in Philadelphia, killing at least 13 people. The deputy fire commissioner stated during a news conference that there were four smoke alarms but none of them worked during the fire.

Most people think of smoke alarms as those annoying devices that go off when you’re pan-searing those delicious steaks. But inside their plastic casing, there are fascinating technologies, making use of light sources and radioactive molecules, to alert us to the presence of smoke. Since their invention in the 1960s, smoke alarms have become integral parts of our homes, often mandated by law. There are two main types of residential smoke alarms, an important fact that is often not mentioned.

If you purchased your smoke detector from the hardware store or your electrician, you likely have an ionization detector, while we recommend and install photoelectric smoke detectors.

You may not know that most house fires are of the smoldering (rather than flaming) type, due to the abundance of flame retardant materials used in furniture upholstery and construction. Photoelectric smoke detectors detect smoldering fires better and faster.
