Honeywell 5800COMBO vs 5808W3

The Honeywell 5800COMBO and the Honeywell 5808W3 are two similar life-safety devices. They both provide smoke and heat detection, and they are both designed to function with the same alarm systems. However, the 5800COMBO offers carbon monoxide detection while the 5808W3 does not.

In terms of overall function and capability, the two devices are actually quite similar. Both are used to detect smoke and high temperatures caused by a fire. Both devices are part of the Honeywell 5800 Series of wireless sensors. As 5800 Series Sensors, both the Honeywell 5800COMBO and the Honeywell 5808W3 communicate at a wireless frequency of 345 MHz. This means that both devices can function with any Honeywell or 2GIG Panel that has an active wireless receiver.

That said, there is one key difference between the Honeywell 5800COMBO and the Honeywell 5808W3. That is the fact that the 5800COMBO includes carbon monoxide detection, while the 5808W3 does not. Because of that, the 5800COMBO serves as a dual-purpose device for detecting both fires and carbon monoxide outbreaks. It can be considered an "all-in-one" life-safety device. On the other hand, the 5808W3 is strictly for detecting fires. If you are using a 5808W3, then you will want to have a separate device for detecting carbon monoxide. One possible device to use for this purpose is the Honeywell 5800CO Carbon Monoxide Detector.

The 5800COMBO and the 5808W3 also differ in some other ways. For one, the 5800COMBO is considerably larger than the 5808W3. While both devices use CR123A lithium batteries, the 5800COMBO requires four batteries, while the 5808W3 only needs one. Both devices have an average battery life of three to five years. After that, the old batteries will need to be replaced with new ones. This will ensure the proper working order of the device in the event of a serious emergency.
