Your fire safety plan may include a family plan for exits, knowledge of fire extinguisher locations, keeping fresh batteries in your smoke detectors, and more.  But does it include heat detectors?

We’ve written about heat detectors previously, more so in a comparison with smoke detectors.  Today, we wanted to drill down a bit more on heat detectors themselves.

Heat detectors are an additional component to your fire safety system; they do not replace smoke detectors.  They are often neglected when systems are installed, but it’s never too late to add them to your home or business.

So you realize you don’t have heat detectors and would like to add them to complement your smoke detectors, but what types are there?  Where should they go?

First of all, there are two types of heat detectors, so you want to make sure you purchase the correct type for the correct location of your house or business.

The two heat detector classifications are fixed temperature (the most common type) and rate of rise.

Fixed temperature heat detectors activate when the detector’s sensor reaches a fixed temperature, at a range beginning at 120 degrees F.

Rate of rise heat detectors measure the rise in temperature over a period of time and the alarm will sound if it deems the temperature rose too fast.  It can activate at a lower temperature than fixed sensors because it’s the rate, not the absolute temperature that is the factor.  They are not ideal for slowly developing fires.

To take the guessing out of which one to install, talk to your security or fire expert about combination heat detectors.

Heat detectors are most often found in attics (where dust particles would disrupt the operation of a smoke detector), utility rooms, kitchens (which produce smoke) and the like.

Fixed temperature models are a good choice for the kitchen not only due the presence of cooking smoke, but also since a fast heating oven can cause the rate of rise type to alarm unnecessarily.

A rate of rise detector might be better in places where a rapidly combustible fire can quickly begin, such as a garage with fuels and chemicals present, or a utility closet.

So the key is to find the areas in your home or business that aren’t covered by smoke detectors, then determine which of the two types of heat detectors would be appropriate for those areas.

Don’t leave anything to chance.  Be sure to speak with a security integrator, a fire official or other fire safety professional.
