How Many Smoke Detectors Do I Need?

Fire doesn’t inform us before striking. More often that not, fire strikes in the least expected times. Statistics has shown fire fatalities are the highest during night and early morning.

Having smoke detectors in our home is the first and important step to preparedness. Smoke detectors give us early warning to fire threats. They also provide valuable time for us to escape to safety.

Then the question is how many smoke detectors do we need? What’s the least we should have? How many is enough? Is there a thing of too many?

SCDF’s Guidelines

Single storey homes (HDB, apartments, condominiums) requires at least 1 smoke detector.

Our Recommendation

While we agree with SCDF’s guidelines, we see that as a very basic guideline. We recommend the following as a minimum instead:

Single Storey

  • 1 smoke detector in the corridor leading to the bedrooms
  • 1 smoke detector in the living/dining room

Multi Storey

  • 1 smoke detector in the living room
  • 1 smoke detector in the dining room
  • 1 smoke detector in the stairwell of each storey

For More Protection

We further suggest that 1 smoke detector is also needed in each bedroom. This helps with early detection of fire threats that originated from bedrooms.

Where To Install Smoke Detectors?

Having smoke detectors is important. Equally important is installing them in a correct way. It isn’t going to be of much use if the detectors fail to detect fire threats.
This is a big topic to cover on its own as it depends a lot of your home layout. You may refer here for some of the watch-outs in installation of smoke detectors.
