Smoke & Heat Detectors Frequently Asked Questions

What is a Smoke/Heat Combination Detector Called?
A sensor that features both smoke and heat detection capabilities is simply called a "smoke and heat detector". Learn about smoke and heat detectors.

How Do I Reset the Fire Alarm on My Security System?
In most cases, disarming the system twice will reset the fire alarm and clear the display. The smoke detector must be free of smoke when doing this. Learn to reset the fire alarm.

2GIG SMKT3-345 vs Honeywell 5800COMBO
Two of the most popular life-safety sensors we offer are the 2GIG SMKT3-345 and the Honeywell 5800COMBO. These devices both offer smoke, heat and low-temp freeze detection. But only the 5800COMBO provides detection for potentially deadly carbon monoxide gas. Learn more about these sensors.
Added:

Honeywell 5809 vs 2GIG SMKT2-345
The 5809 and the SMKT2-345 are both life-safety devices designed to alert people to the presence of a fire. The SMKT2-345 can sense smoke and high temperatures, while the 5809 can only sense high temperatures. They are also manufactured by different companies. Learn more about these two devices.

When Is It Better to Use a Heat Detector Instead of a Smoke Detector?
There are a few situations in which it is better to use a heat detector instead of a smoke detector. This most includes rooms where smoke may be occasionally present. Heat detectors are also used in dusty areas where fine particles may prevent a smoke detector from function properly. Learn more about heat detectors.

Honeywell 5809 vs 2GIG SMKT3-345
The Honeywell 5809 and the 2GIG SMKT3-345 are two different life-safety devices. They are manufactured by different companies, and their system compatibilities are slightly different. Also the 5809 is only a heat sensor, while the SMKT3-345 offers multiple uses. Learn more about these two sensors.
Added:

How Does a Fire Detector Work?
There are two primary methods for detecting a fire. These are through either smoke detection and heat detection. For that reason, a "fire detector" is more commonly referred to as a "smoke detector" or a "heat detector". There are also combo smoke and heat sensors. Learn more about these devices.
Added:

What's the Best Place to Install a Smoke Detector?
When choosing a location for a smoke detector, there are some things to remember. For example, it should be placed away from any vents or ducts that might affect its performance. It should also be at least 10 feet away from any kitchen appliances. Learn more about where to place a smoke detector.
Added:

Honeywell 5800COMBO vs Honeywell 5809
The 5800COMBO and the 5809 are both wireless fire sensors from Honeywell. The 5809 is for heat detection only, while the 5800COMBO is used for heat, smoke and carbon monoxide detection. Both sensors will interface with the same alarm systems. Learn more about these life-safety sensors.
