Choosing To Invest In Security

When you own a business, you have two choices. You can either decide to invest money in replacing stolen goods, or to invest money in a nice security system. When I first started my business, I decided to ignore security measures altogether, which caused me to net a loss for the year. However, after a suggestion from my mentor, I decided that it might be wise to install a nice security system. You wouldn't believe how much better things got. Within a few weeks, theft was almost completely eliminated. My blog is all about helping you to tighten up security measures.

Choosing Between Photoelectric And Ionization Smoke Detectors

by Victoria George

Before you head out to your local hardware store to purchase smoke detectors for your new home, it is important that you understand that difference between the two types of smoke detectors that you can choose from:

  1. photoelectric smoke detectors
  2. ionization smoke detectors

Here is some information on each type of smoke detector to assist you with making this vital choice:

How Photoelectric Smoke Detectors Work

Photoelectric smoke detectors utilize a small beam of light that is contained within a small chamber that is filled with air. When smoke from a house fire enters into the chamber of air, the light beam is diffracted through the smoke and reflects on a small photoelectric cell. When the beam of light comes into contact with the photoelectric cell, then it activates the audio signal of the smoke detector that signals you that there is a fire.

Photoelectric smoke detectors respond very quickly to the light smoke produced by fires that start with a long, slow smolder. An example of this type of fire is an electrical fire that starts in a wall from an outlet short or from rodent damage. Rodents chewing on electrical wires can cause small holes in the wires that can spark and cause surrounding building materials to catch on fire.

How Ionization Smoke Detectors Work

Ionization smoke detectors contain a tiny amount of radioactive material that is placed between two ionizing plates. When smoke is produced by a fire, it enters the smoke detector and disrupts the flow of radioactive ions between the plates. This interruption causes the smoke detector to sound an alarm and let you know that there is a fire.

Ionization smoke detectors work more quickly when there is a fire with large flames and are less responsive to those that smart by smoldering for a long time, such as an electrical fire contained within a wall. This type of smoke detector works well with kitchen fires.

How To Pick The Type Of Smoke Detectors To Install

Since each type of smoke detector works better in certain situations than the other, to provide the best protection for your home, you should install both types of smoke detectors. Install the ionization type near the kitchen and garage where open-flame fires are the most common, and install photoelectric in the other areas of your home to protect against electrical fires.

How To Keep Smoke Detector Batteries Working

Finally, both photoelectric and ionization smoke detectors utilize batteries to complete the circuits that make them work. For this reason, it is very important that you chance the batteries in your smoke detectors twice each year to ensure that your home and family are always protected. The easiest way to remember to change your smoke detector batteries is to do it when you chance your clocks forward for daylight savings time and back to standard time.
