How Many Zones are Available on a Honeywell Home PROSIXC2W?

Eight (8) zones are available on a Honeywell Home PROSIXC2W. Each zone in use must be set up with an end-of-line resistor (EOLR). Calibration allows for resistor values from 1k to 10k. Up to two (2) powered sensors can be powered from the module, and no life-safety sensors can be used.


The Honeywell Home PROSIXC2W is a wired to wireless converter used with the Honeywell Home PROA7PLUS System or the Resideo PROA7PLUSC. Wired sensors connect with the PROSIXC2W so that they can then be successfully integrated with the PROA7PLUS. Each wired zone set up with the PROSIXC2W will use one of its eight (8) on-board inputs. This is down one zone from the popular Honeywell 5800C2W, which has nine (9) available zones. Any wired sensor used with the PROSIXC2W will be seen by the PROA7PLUS System as a wireless PROSIX Series Sensor and it will be assigned one of the corresponding wireless zones on the system.

There are some important things to keep in mind regarding the PROSIXC2W. First, any zone in use on the module must be set up with an EOLR that is wired in either Series or Parallel depending on the sensors being used. The PROSIXC2W supports EOLR learning, and you can use resistors ranging in value from 1k to 10k. The unit comes with 2.2k resistors color-coded red-red-red-gold for those situations where a panel that did not require the use of EOLRs is being replaced. You should complete the full wiring process for the PROSIXC2W, the sensors, and the EOLRs before calibrating the unit for EOLR learning. All zones in use must be in their normal, non-faulted state at the time of calibration. Any zone that is open, or otherwise faulted at the time of calibration will be treated by the module as if it does not exist. The calibration process will need to be reperformed if you change or replace any of the sensors or EOLRs used with the unit.

There is also a big restriction regarding the types of sensors that you can use with the PROSIXC2W. No life-safety sensors can be used with the PROSIXC2W Converter. This means that you cannot use any wired smoke detectors or carbon monoxide (CO) detectors with the PROSIXC2W and expect them to interface with the PROA7PLUS System. Additionally, each PROSIXC2W unit is only able to support up to two (2) powered sensors that use 4-wire connections. Examples of wired sensors that typically draw power and require a 4-wire connection include most motion sensors and glass break detectors. If you need to use additional powered sensors, then you should consider getting an auxiliary power supply or an additional PROSIXC2W Converter. The PROSIXC2W is capable of providing up to 12VDC and 100mA of power for the allotted connected devices. Also keep in mind that each zone used with the PROSIXC2W must be assigned to the same partition on the PROA7PLUS System.
