Smoke Alarms:

Smoke alarms use two types of technology.

Ionization technology is generally more sensitive than photoelectric technology at detecting small particles, which ten to be produced in greater amounts by flaming fires, which consume combustible materials rapidly and spread quickly. Sources of these fires may include paper burning in a wastebasket, or a grease fire in the kitchen.

Photoelectric technology is generally more sensitive than ionization technology at detecting large particles, which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.

For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home. Click here for more on the difference between ionization and photoelectric smoke alarms.

Signaling Systems Tip:

When using a lamp that plugs into a signaler or transmitter, there are several light bulb options to choose from.
  • Instant-on CFL (compact fluorescent light): The key here is the instant-on feature, available at Lowes and Home Depot, among other hardware stores and online. The good news is they have a life about 10 times longer life than incandescent type bulbs, and end up costing about 50% less than the incandescent type. They also use a lot less energy, saving even more. A 13-23 watt instant-on CFL compares to a 60-100 watt incandescent light bulb and sells for about $3 each. These
  • Halogen: Halogen bulbs also works well. They provide a warmer light than the CFL type, however the down side with this option is the cost. Halogen can cost up to 2 times more than the instant-on CFL type. The good news is as incandescent bulbs are phased out, the halogen bulb will begin to drop in price.
  • LED: LEDs also works well but can be quite expensive, averaging about $18 per bulb or more.
  • Incandescent: Stock up on these while still available. The average incandescent bulb can last up to 5 years or longer when used with our signaling products.
