Smoke & Heat Detectors Frequently Asked Questions

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.

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.

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.

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.
Added:

Will a Smoke Detector Detect Heat?
Not all smoke detectors are designed to detect the presence of high heat. These sensors will only detect high heat if that is a specific function of the device. Otherwise, a smoke detector will only detect smoke, and nothing more. Learn more about smoke detectors and their functionality.
Added:

Conventional vs Monitored Smoke Detectors
Both conventional smoke detectors and monitored smoke detectors are life-safety devices that activate upon detecting smoke. But only a monitored smoke detector can contact a central station for help. A conventional smoke detector is just a noise-making device. Learn more about smoke detectors.

Honeywell 5800COMBO vs 5808W3
The 5800COMBO and the 5808W3 are both life-safety devices from Honeywell. They communicate at the same frequency, and they are compatible with the same alarm systems. However, the 5800COMBO offers carbon monoxide detection, while the 5808W3 does not. Learn more about these two devices.
Added:

Honeywell 5800COMBO vs 5806W3
The 5800COMBO and the 5806W3 are two life-safety devices. Both are from the Honeywell 5800 Series, and both communicate at a frequency of 345 MHz. However, the 5800COMBO provides smoke, heat and CO detection, while the 5806W3 only provides smoke detection. Learn more about these two sensors.
Added:

How Do I Change the Battery in the 5800COMBO?
The 5800COMBO is powered by four CR123A lithium batteries. To change these batteries, start by removing the device from its back plate. Then replace the old batteries with four new ones. Then reapply the device to the back plate. Learn more about replacing the batteries in a Honeywell 5800COMBO.

Can I Monitor My Existing Smoke Detectors Remotely?
Smoke detectors for a security system can be monitored through Total Connect or Alarm.com. The platform that is used will depend on the type of panel you have.
