How Important Are Smoke Detectors?

During the course of the home inspection I will be checking for the presence of Smoke Detectors. I cannot stress enough the importance of a functioning Smoke Detector. Most people recognize and understand the importance of a functioning Smoke Detector.

 

HISTORY OF THE SMOKE DETECTOR

I remember when Smoke Detectors were first introduced in the 70’s. Professionally installed Smoke Detectors for a typical three bedroom was in the neighborhood of $1,000 . As with most technology, the cost has been reduced substantially. Today you could protect the same house for less than $100. Pretty cheap investment for the first line of defense for your home.

WHERE SHOULD YOU PUT THIS SMOKE DETECTOR?

You should install smoke detectors in every bedroom, in the hallways leading to the bedrooms, and on each level of your home, including the basement if you have one. Smoke detectors should be mounted on the ceiling 4” from the wall. Wall mounted Smoke Detectors should be 4-12” from the ceiling. Do not install near draft areas (windows, vents.). You should also have an escape plan for your family. Call your local fire department if you are unsure about placement.

TYPES OF SMOKE DETECTORS

There are several types of Smoke Detectors. I’m just going to mention the most common two. The basic battery operated smoke alarm will typically cost from $10-$20 each. They are usually installed using a screw driver, or sometimes just an adhesive pad. They operate with just a 9V battery, which should be renewed annually. They are “tested” by pushing a button which will sound a short audible “beep”. This does not “test” the smoke sensor, it just test the alarm. This is the “test” typically done during a home inspection.

HARD-WIRED SMOKE DETECTOR

The “hard-wired” smoke detector is actually connected to a 110 volt circuit in your home and may or may not have a battery back-up. I suggest that you purchase the model with the battery back-up. These will usually cost about $25-$30 each, and should be professionally installed by a licensed electrical contractor. These can be installed “in series”. This means that when one alarm sounds, they will all sound the alarm.

MAINTAINING YOUR SMOKE DETECTORS

– Clean regularly. Dust and debris will interfere with normal operation.
– Replace batteries at least once a year.
– Schedule regular maintenance and tests. Monthly is recommended.
– Never remove batteries to disable an alarm that sounds every time you cook. The alarm is      working fine, it’s your cooking habits that may need investigating or adjustment.

DO SMOKE DETECTORS LAST FOREVER?

No! The life expectancy of a Smoke Detector is 8-10 years. If yours are older than that, they should be replaced.  I usually recommend replacement if you don’t know the age of the Smoke Detector. A home inspection cannot determine the age of the Smoke Detector.

I HOPE YOU ENJOYED THIS LITTLE BIT OF INFORMATION. AS ALWAYS IF YOU FEEL UNCOMFORTABLE PERFORMING ANY OF THESE TASKS, PLEASE CONSULT A PROFESSIONAL.
