How Do I Setup Low-temp & Freeze Detection On a 5800COMBO?

You can setup low-temp and freeze detection on a 5800COMBO by setting the device to loop number 3 within zone programming. The loop number of 3 tells the 5800COMBO to function as device for sensing dangerously low-temperatures. Each loop number on the device provides a different function.

On a 5800COMBO, loop number 1 is set for smoke and heat detection. Loop number 2 is set for device maintenance. Loop number 3 is set for low-temperature sensing. Each loop number will require its own unique wireless zone in order for that function to go into effect on the sensor. Additionally, the 5800COMBO can also utilize a wireless zone with a separate serial number in order to be used for carbon monoxide detection. This means that up to four different wireless zones can be taken up by one single 5800COMBO device.

The purpose of these four zones is as follows:

1. Smoke and Heat Detection
2. Carbon Monoxide Detection
3. Low-Temperature and Freeze Detection
4. Maintenance

With the 5800COMBO set to perform low-temperature and freeze detection, the device will activate once the detected temperature falls below 41°F. However, the panel will not acknowledge this until it receives a check-in signal from the 5800COMBO sensor. This could potentially take up to 90 minutes after the low temperature has been detected. Once the sensor detects higher temperatures, the issue will clear on its own.

Complete the following steps to program a 5800COMBO for low-temperature and freeze detection on a Lynx Touch or Lyric Controller:

1. Access zone programming. From the home screen of the panel, go to Security > More (if using Lynx Touch) > Tools > enter installer code (4112) > Program > Zones. This will take you into zone programming.

2. Choose a wireless zone. Find an available wireless zone, and click on it to highlight it. Then click edit at the bottom of the screen. This will take you into programming for that zone.

3. Choose loop number 3. Locate the field of "Loop Number". Click on that field to toggle between different loop numbers. Keep clicking until it is assigned a loop number of 3.

4. Finish programming. Go through each field to configure the settings for the device. This will include learning in the sensor.

Then keep pressing the return arrow in the upper-right corner of the screen until you return to the main menu. Make sure that you select "Yes" when asked if you want to allow the installer to re-enter programming.
