Why Do I have a Trouble Condition On My Honeywell Home PROSIXC2W?

You have a trouble condition on your Honeywell Home PROSIXC2W because there is an issue with the module that requires your attention. Possible trouble conditions for the Honeywell Home PROSIXC2W Wired to Wireless Converter include AC Loss, Low Battery, RF Supervision Loss, and Cover Tamper.


When a trouble condition occurs for a PROSIXC2W, all associated zones programmed on the PROA7PLUS System will show the corresponding trouble condition. Additionally, for an AC Loss trouble condition, LED light number 4 on the PROSIXC2W will be blinking Red every second to indicate that the module is running on battery power, and DC power from the unit's plug-in transformer is not present. Please note that if both AC Loss and Low Battery conditions occur simultaneously, then the PROSIXC2W will simply power OFF, and no LED lights will be illuminated. For all other trouble conditions, no LED light changes occur on the PROSIXC2W. This applies to Low Battery, RF Supervision Loss, and Cover Tamper.

Also note that it is possible to get a trouble condition for a single PROSIXC2W zone, without there necessarily being something wrong with the PROSIXC2W itself. For example, if a sensor on the PROSIXC2W is configured with a Response Type that causes a trouble condition (e.g. a Day/Night Zone), then it may be that a sensor faulted, and the PROSIXC2W is merely reporting the fault like it is supposed to. Consider the Response Types that have been configured with your PROSIXC2W zones, and determine if the trouble might just be the result of a faulted zone. It's also possible that trouble conditions may occur due to the module being calibrated improperly. Always make sure to perform a proper calibration with the PROSIXC2W during its setup process. This means having all zones properly wired with end of line resistors ranging in value from 1k to 10k, and having all zones in their restored positions (not faulted) at the time of the unit's calibration.

Here is a breakdown of the four (4) trouble conditions you may encounter with the PROSIXC2W if something is wrong with the unit itself, plus what you should check for if you notice one. The key thing to note here is that every zone configured through the PROSIXC2W will display the trouble condition, not just a single zone. If you are getting the same trouble condition across all your PROSIXC2W zones, then it is likely that one of the issues listed below is to blame.

AC Loss: This indicates that the PROSIXC2W is not receiving sufficient power from its plug-in 5VDC transformer. This could be because the transformer came unplugged, the wire connecting the transformer and the module has been cut or severed, an electrical outage occurred, or because insufficient electrical current is reaching the panel. This could be because the wire connecting the converter and the transformer is too long. If AC Loss occurs, and battery power is still present, then the fourth (4th) LED light on the PROSIXC2W will be blinking red. If battery voltage drops below 3.4VDC during an AC Loss condition, then the PROSIXC2W will shut down entirely. To prevent AC Loss, consider using the set screw with the transformer to prevent it from being unplugged accidentally. Also consider getting a backup generator for the building to prevent AC power loss when electrical outages occur. Make sure that the wire connecting the converter and the transformer is protected and that it never becomes cut, severed, or damaged in any manner. Lastly, always make sure to stay within the recommended maximum wire run limit for the transformer based on the wire gauge (AWG) you are using. For reference the maximum lengths are, 18 AWG - 16 Feet; 20 AWG - 10 Feet; 22 AWG - 6 Feet.


Low Battery: This indicates that the PROSIXC2W is detecting less than 3.6VDC of power from its connected battery, or that no battery power is being detected at all. Open up the unit to check and make sure the battery is properly connected. If it is, try giving the battery time to recharge with the unit running on AC power. If the battery has reached its end of useful life (about 3 to 5 years), then consider replacing it. The Battery Part Number is 300-10342. Please note that there is no visible warning indicator on the PROSIXC2W Converter itself for Low Battery, but you will get a Low Battery trouble condition for each associated zone on the PROA7PLUS System. Also note that if battery voltage drops below 3.4VDC and AC loss occurs, then the PROSIXC2W unit will power down entirely.

RF Supervision Loss: This indicates that the PROA7PLUS Panel did not receive a regularly scheduled check-in signal from the PROSIXC2W unit. No visible indication will be shown on the PROSIXC2W, but you will get an RF Supervision Loss trouble condition for each associated zone on the PROA7PLUS System. If this issue occurs, check and see if either the PROSIXC2W or the PROA7PLUS Panel has been moved since the last successful check-in. Moving the devices further apart could cause supervision issues. Also, consider if any new obstacles have been placed or installed between the two devices that may disrupt RF signals from reaching their intended destination. Examples of obstacles may include other electronic equipment and/or large metal objects.

Cover Tamper: This indicates the cover for the PROSIXC2W is loose or has been removed entirely, thereby causing the tamper switch on the unit to not be pressed down. It's possible that someone may have tried to open up the module. Check the PROSIXC2W and see if the cover is present and fitted properly. You will not get any visual notification on the PROSIXC2W Converter itself for a Cover Tamper, but you will get a Cover Tamper trouble condition for each associated zone on the PROA7PLUS System.
