Honeywell Home PROSIXC2W ProSeries Hardwired-to-Six Wireless Converter: Installation Notes

Q: Why does my zone show trouble?

Most common: low battery, tamper open, out of range, or wrong sensor type for the panel receiver (5800 Series vs SiX wireless).

Q: Where is official documentation?

Q: How do I test after installation?

Use panel walk test, zone status, and (if monitored) central station test per dealer procedure.

Q: Can I mix 5800 and SiX sensors?

SiX sensors require ProSeries or Lyric; 5800 needs a 5800 receiver transceiver hardware — they do not enroll on the standard 345 MHz receiver alone.

Overview

SiX Series two-way encrypted sensor — ProSeries/Lyric wireless family with supervision, tamper, and encrypted RF (SiXCT, SiXPIR, SiXGB, SiXFOB, etc.).

On Honeywell systems, wireless devices are supervised zones on the panel — tamper, low battery, and missing signals appear as trouble conditions that may block arming depending on panel programming.

At a Glance

Specification	Details
Wireless	SiX 2-way encrypted to ProSeries/Lyric
Supervision	Enhanced status vs one-way 5800
Power	Battery per SKU
Enrollment	Panel SiX learn mode

What This Device Does Well

Provides reliable supervised status at the panel and Total Connect 2.0 when installed, enrolled, and range-tested correctly.

Before You Service or Replace One

Sensor SKU — 5800 Series one-way vs SiX two-way encrypted vs hardwired.
Panel online — resolve panel AC/cell trouble before blaming sensor.
Range — 5800RP repeater or move 5881EN/6160RF receiver path for distant zones.
Battery type — use listed cell; replace all batteries in multi-cell devices.
Tamper — cover fully closed before declaring hardware fault.

Official Sources

Use official Resideo install PDFs and install guides for exact wiring, enrollment, and firmware — specifications vary by SKU and region.

Compatible Peripherals

This page lists Honeywell Home ecosystem compatibility — panels, transceivers, repeaters, and monitoring platforms — not third-party panel brands unless using an approved takeover path.

Host compatibility

Host / ecosystem	How it connects
PROA7 / PROA7PLUS	SiX sensor enrollment
Lyric Controller	SiX devices per Lyric firmware

Not compatible / common mistakes

SiX sensors on VISTA without compatible host — use 5800 Series instead

Replacement guidance

Match SKU and encryption generation on product label before ordering.
Delete old zone/device in installer programming before enrolling replacement.
Document zone number and name for user and central station records.
Run walk test and communication test after swap on monitored accounts.

Installation Notes

Follow SiX sensor installation guide and the official resource links in this product folder for mounting, wiring, and enrollment.

Pre-install checklist

Confirm panel model (VISTA/Lynx/ProSeries/Lyric) and encryption requirements.
Verify dealer cell account and module SKU before cell install.
Document installer code and existing zone map for takeover jobs.
Plan antenna routing (ANT5XL) when panel location has poor cell RSSI.
Have listed batteries and tools for sensor mounts before enrollment.

Typical install sequence

Mount and power panel; apply firmware updates per dealer bulletin.
Install cell module and run communication test / Total Connect 2.0 activation.
Enroll wireless sensors via installer Learn mode; label zones.
Include Z-Wave devices after excluding from any prior hub.
Install 5800RP repeater or optimize receiver placement before fringe 5800 sensors.
Run walk test, user code training, and central station test if monitored.
