What Is a Honeywell Home PROSIXC2W?

A Honeywell Home PROSIXC2W is a wired to wireless converter unit for a Honeywell Home PROA7PLUS or a Resideo PROA7PLUSC. The converter is used for integrating hardwired sensors with the PROA7PLUS that would otherwise be incompatible. Up to eight (8) wired zones are supported on a PROSIXC2W.

If you are familiar with other wired to wireless converter modules, such as the Honeywell 5800C2W, the Qolsys IQ Hardwire 16-F, and the DSC PG9WLSHW8, then you should already have a good understanding of how the Honeywell Home PROSIXC2W works. Hardwired sensors connect to the zone terminals on the PROSIXC2W. From there, the PROSIXC2W communicates with the PROA7PLUS System wirelessly. The PROA7PLUS will recognize the connected hardwired sensors as wireless sensors. The system will treat these devices as PROSIX Series Sensors, and they will be able to enroll with the corresponding wireless zones on the the PROA7PLUS System. All wireless communication between the PROSIXC2W and the PROA7PLUS is protected using 128-bit AES encryption. This is the same type of wireless encryption protection used with any PROSIX Sensors for the system. Please note that each zone used with the PROSIXC2W must be assigned to the same partition on the PROA7PLUS.

The PROSIXC2W supports EOLR learning and calibration so that resistors ranging in value from 1k to 10k can be used. The PROSIXC2W comes with 2.2k resistors, color-coded red-red-red-gold, for cases where the original panel being replaced did not use resistors for one or more zones. Resistors can be wired in Series for normally closed sensors or Parallel with normally open sensors. The unit and all the sensors and resistors should be wired properly before performing the calibration process for the device. Any spare zones on the PROSIXC2W should remain open, with no resistor connected. All devices connected to the converter should be in their normal position, meaning without faults, when calibration takes place. Any faulted zone at the time of calibration will not be seen by the PROSIXC2W. The calibration process will need to be reperformed whenever a change is made to a connected sensor and/or the EOLRs used with the PROSIXC2W.

There are some other miscellaneous details to keep in mind regarding the PROSIXC2W. If you are using 4-wired sensors that draw power from the PROSIXC2W, then only two (2) wired sensors can be used in this manner. If you have additional powered sensors beyond the allotted two, then you will need an additional PROSIXC2W unit or an external power supply. The PROSIXC2W is capable of provided a maximum of 12VDC and 100mA of current for the two allotted devices. The PROSIXC2W gets primary power from a plug-in 5VDC transformer that comes included with the unit. You must supply your own wiring. The best size of wire to use is 18 AWG to 22 AWG 2-conductor wiring, or you can use a Honeywell LT-Cable. Polarity must be observed, so remember that red is for positive (+), and black is for negative (-). The PROSIXC2W also comes with a lithium ion backup battery rated at 3.6VDC, 2480mAh. Also, no life-safety sensors should be used with the converter. This includes any wired smoke detectors and carbon monoxide (CO) detectors.

Please note that the user will not be able to complete enrollment themselves, unless the PROA7PLUS System supports local end-user programming. Without end-user programming, all zone programming will need to be completed remotely by the user's alarm monitoring company. This includes any wired sensor for the PROA7PLUS that is set up through the PROSIXC2W. Resideo says that local programming will be made available for the PROA7PLUS in a future firmware update. But as of January, 2021, no PROA7PLUS System supports local end-user programming.
