Can Honeywell 5800COMBOs be Interlinked?
An unfortunate downside of the Honeywell 5800COMBO is that multiple units of these devices cannot be interlinked. This means that there is no way to set-up a "one go, all go" function with 5800COMBO devices. However, this can be done on Honeywell SiXSmokes. Learn more about the 5800COMBO.

How Do I Setup Low-temp & Freeze Detection On a 5800COMBO?
In order to setup a Honeywell 5800COMBO for low-temperature and freeze detection, you must set the device to loop number 3 within zone programming. This is the loop number that tells the device to function as a low-temperature sensor. Learn more about the Honeywell 5800COMBO and its functions.

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.

How Do I Turn Off Sensor Supervision for a Honeywell 5800 Series Motion Sensor?
Sensor supervision on a 5800 Series Motion Sensor is used by an alarm system to check-in with the sensor and make sure that it is within range and communicating properly. Turning this off will have the panel not look out for any check-in signals from the sensor. Learn more about sensor supervision.
