Ideally smoke alarms and detectors should last anywhere from 8-10 years but given the importance of maintaining a working smoke detector, it is smart to check and make sure yours is working properly every six months or so. And remember that when you do replace your entire smoke detector unit, you should write the date of installation so that you’ll remember the exact date of purchase or installation. And whenever you are installing a new smoke detector, make sure to following the manufacturers instructions for installation and replacement.
It is incredible important to have a working smoke detector in every area of your home—did you know that every year 2,600 Americans die in home fires and over half of these die between the hours of 10pm and 7am. A smoke detector in these homes could have saved lives.
There are several types of smoke detectors available on the market today. These include ionization alarms that sense the heat from flaming fires. These alarms have a small bit of radioactive material between two electrically charged plates. When heat reaches the air around the alarm, this ionizes the air and causes it to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions and activates the alarm. Photo-electric alarms are more sensitive to smoke levels than flash, high-heat fires. These arms have a light source aimed at a sensing chamber. When smoke enters the chamber, the light is reflected onto the light sensor and the alarm trips. More and more, companies are offering combination alarm systems to customers. This means that one never needs to compromise on an alarm meant for high-heat fire or for smoldering and very-smoky fire. Here at Allied Fire and Security, we hope that you’ll do your research before installing anything.
And remember, there is nothing more important than your and your family’s safety.
